I have moved a little away from the original topic, namely, data recovery in the event of a file system failure. This case refers to “logical data recovery” and is applicable in such cases as data deletion (erroneous and intentional) and drive formatting (with or without data overwriting).
Steps to recover files from a failed flash drive:
1) Connect the drive to the USB connector of the PC;
2) Launched the PC 3000 Flash software and created a new task by selecting the required drive from the list of connected ones;
3) Created full image(not compressed) drive, so that all further work is carried out not with a live drive, but with its sector-by-sector copy, which is a more reliable method, because if a physical flash drive is used for a long time, it may fail or some other incident may occur;
4) After the disk image is created, the task in which the image was created is closed, the failed flash drive is correctly disconnected and removed from the PC;
5) A new task is created in the complex, but the image of our flash drive, which was created in the previous paragraph, is specified as the drive;
6) To assess the state of the file system, the "Disk Analysis" method is launched, after which all file systems and metadata are searched.
In this case, the analysis showed that it is not possible to restore the files as they are while preserving the entire structure and hierarchy, since there is no way to collect file system. This is not a problem, because in this case the data is also recoverable, with one exception - this will be a “draft data recovery method” - files are restored not by folder structure, but by file type. For example: all *.jpg files will be in one folder, text with text, and so on, which will be much better than not restoring the client’s data at all. Considering that the client mainly needed photographs from this flash drive, this was not critical for him.
In such cases, as described here, it is very difficult to recover data on your own and can only make things worse. This is why we recommend turning to specialists, since data recovery after formatting is best left to experts in their field.
If we talk about the big picture, then if the error “The disk must be formatted before using in drive F:*” occurs, the data can be successfully recovered using professional tools and knowledge of the matter. That's all for me, and a little later I'll do short video on the topic of logical recovery and the draft method in general.
For normal operation of the hard drive, it is necessary that it have a partition table (sometimes called partition although strictly speaking partition- these are the disk partitions themselves). If it is absent, the operating system does not have access to the hard drive (“does not see” the hard drive). The partition table contains information about the physical characteristics of the disk: the number of sides, the number of tracks and sectors per track, as well as information about partitions and logical drives.
Disk partitions
When working under MS-DOS, each hard drive can have the following partitions:
- Primary DOS partition: required. In this section, a single system logical drive is formed (usually named C:)
- Extended DOS partition: present only when the hard drive has two or more logical drives.
- Non-DOS partition: formed if you work with two or more operating systems. This partition is given to other operating systems for use and is invisible to MS-DOS.
FDISK Team
To execute this command, you must have a boot floppy disk made in Windows 98SE, preferably in Russian. Although the operating system comes with an external command FDISK, but in English.
After booting the computer from the floppy disk, enter the command
The main menu will appear on the screen:
FDISK Options
( FDISK options)
Current fixed disk drive: 1
(Current hard drive disk: 1)
Choose one of the following:
( Choose one of the options :)
1.Create DOS partition or Logical DOS Drive
( 1. Create a DOS partition or DOS logical disk.)
2.Set active partition
( 2. Set the active partition.)
3.Delete partition or Logical DOS Drive
( 3. Delete a DOS partition or logical drive.)
4.Display partition information
( 4. View partition information.)
5.Change current fixed disk drive
(5. Change current drive hard drive.)
Enter choice:
(Enter your choice:)
Press Esc to exit FDISK
(Press Esc to exit)
Note: If there is only one hard drive installed in the computer, then option 5 is not issued.
Hard drive partitioning
To partition a hard drive, you must perform the following operations:
- Make the reconfigurable drive active (if necessary)
- Delete all existing partitions on the hard drive.
- Create new sections you need.
- If necessary, create logical drives.
- If necessary, assign an active partition (it will boot from)
- Format the resulting logical drives.
Removing existing partitions
If your disk has already been configured, you will first have to remove the previous partition. To do this, select item 3 of the main menu. The following will appear on the screen:
Delete DOS Partition or Logical DOS Drive
(Removing DOS partitions or logical drives)
Current fixed disk drive: 1
(Current drive: 1)
Choose one of the following:
(Choose one of the options:)
1. Delete Primary DOS Partition
(1. Delete primary DOS partition)
2. Delete Extended DOS Partition
(2. Delete extended DOS partition)
3. Delete Logical DOS Drive(s) in the Extended DOS
(3. Remove logical drives from extended DOS partition)
4. Delete Non-DOS Partition
(4. Delete non-DOS partition)
The order of your actions:
- Delete the non-DOS partition (if it exists)
- Remove logical drives from the extended DOS partition (if this partition exists), and when deleting you will need to confirm your intentions several times and enter the drive label.
- Delete the extended DOS partition itself (if you had one), and when deleting you will need to confirm your intentions several times.
- Delete the primary DOS partition, and when deleting you will need to confirm your intentions several times and enter the disk label.
Now the previous split is deleted and you can create a new one.
Create a new split
After deleting the previous partition, you need to create a new one. To do this, select option 1 from the main menu.
Create DOS partition or Logical DOS Drive
(Creating DOS partitions or logical drives)
Current fixed disk drive: 1
(Current drive: 1)
Choose one of the following:
(Choose one of the options:)
1. Create Primary DOS Partition
(1. Create a primary DOS partition)
2. Create Extended DOS Partition
(2. Create an extended DOS partition)
3. Create Logical DOS Drive(s) in Extended DOS Partition
(3. Create logical drives in the extended DOS partition)
First you need to create a primary DOS partition. Select option 1. You will be asked the question:
Do you wish to use the maximum available size for a Primary DOS Partition and make the partition active
(Y/N...............?
(Do you want to use all disk space for the primary DOS partition and make this partition active?)
If you answer yes, then one logical disk will be created on your entire hard drive, from which the operating system will be loaded.
In this case, the hard drive partitioning is complete. If you want to split your hard drive into several logical ones, then you must answer in the negative. The following request will be displayed on the screen:
Enter partition size in Mbytes or percent of disk space (%) to create a Primary DOS Partition.................:
(Enter the size of the primary DOS partition in MB or as a percentage of disk space.)
After you create the primary partition, you will need to create an extended DOS partition.( Create Extended DOS Partition)
A message will appear on the screen:
Enter partition size in Mbytes or percent of disk space (%) to create an Extended DOS Partition.........:
(Enter the size of the extended DOS partition in MB or as a percentage of disk space.)
If you do not need to leave space for working with another operating system (not MS-DOS), then you must specify all the disk space remaining free, which is what is suggested by default.
After you have created an extended DOS partition, you need to split it into logical drives.( Create Logical DOS Drive(s) in Extended DOS Partition)
Enter Logical drive size in Mbytes or percent of disk space (%)...
(Enter the logical disk size in MB or percentage of disk space.)
If you want to create two logical ones (one is the primary DOS partition, the other is the full size of the extended DOS partition), then you need to accept the default maximum size suggested. Otherwise, enter your size and repeat this operation for the next logical drive.
After dividing the hard drive into partitions and logical drives, you need to install the active partition (the computer will boot from it).
Setting the active partition
To boot from a hard drive, the primary DOS partition must be active. Select option 2 from the main menu and enter the partition number from which you will boot:
Enter the number of the partition you want to make active......:
(Enter the partition number you want to make active)
When partition information is displayed, the active partition is marked with the letter A.
After completing these steps, partitioning the hard drive is complete. All that remains is to format the resulting logical drives.
Note: If none of the partitions are made active, then it is impossible to boot from the hard drive. In this case, no messages are displayed.
Formatting the hard drive
Formatting a hard drive has some features. First, drive C: must be made system.
Secondly, you will have to format the hard drive after booting from a floppy disk. After booting from the floppy disk, enter the command:
A warning will be displayed on the screen that you are formatting the hard drive:
Warning: all data on non-removable disk
Drive D: will be lost!
A follow-up question will be asked:
If your answer is positive, the hard drive will be formatted and the operating system will be transferred to it.
After this, you can boot from the hard drive and transfer the files you need to it ( operating system), and, if necessary, format the remaining logical drives (the S parameter, of course, no longer needs to be specified). The process of reconfiguring the hard drive is completely completed.

Question: Error 0x0000007B after repartitioning the hard drive
Hello, when I boot up my computer I get error 0x0000007B. After what did she appear? My hard drive was divided into two partitions - C: and D:. On C: there is Windows 7, on D: a lot of memory is occupied, although I measured the files, and their volume occupied much less than what is written in the properties. More than 100 GB were occupied to nowhere. I decided to create new section, transfer everything you need there, and format it. When the volume was compressed, 60 GB were freed up, I created a new volume and moved part of it there necessary files. The volume was no longer compressed, it said that 0 MB was free for compression, although it also seemed like about 100 GB was free. I read that Acronis Disk Director can handle all problems. I installed it, started to free up space, he asked me to reboot the computer, after the reboot nothing changed. Installed Paragon Partition Manager, there was some kind of error, and I downloaded another version, installed it, and remembered that the old one needed to be deleted. I started deleting, I thought I was deleting new version, and canceled the deletion, after which everything became dull, programs began to disappear, a black screen remained, and then an error appeared. Now when the system is restarted it always appears. Startup restore doesn't help. Restoring from a restore point gives an error, the latest system configuration does not help either. Even when I select recovery, when I select the operating system, it loads and then asks me to select an operating system, although there is none in the table.
Will it be possible to restore the system startup without deleting the necessary files? If not, then I can still delete it, have it on another computer, it just takes a very long time to transfer, and I’m not sure that everything is there.
Sorry for the quality of the photos, they were not taken for the topic, I’m sitting with Dr. Web Live USB.
If necessary, I’ll post the AIDA64 report, but I need to reboot.
Thanks in advance!

"I booted from a flash drive with Windows PE on it, opened iso file Windows, which was on another flash drive, clicked on setup.exe, selected full installation, after which an error began to appear when loading from the hard drive"
Why is this so? There are normal ones standard methods: from DVD, Internet or bootable flash drive, but not like that.
When installing and formatting as needed.
According to your SMART, I just took a quick look: there are errors, they seem to be uncritical, but I’ll review them later.
If you perform all the actions this way - incorrectly, in your own way, then the problems will not disappear. Maybe you have someone who can help, someone who is good at computers?
What error is coming out now, is it the same? If it's different, show me.
Question: Missing disks
There is an old server running Windows 2003, with three mirrored RAID arrays built on it (the system has three logical drives).
A week ago, one logical drive disappeared from the system. After a reboot it appeared back. In the system logs for this day and the previous one there were a bunch of warnings from dmio that it was not possible to write to disk. Periodically, a message appeared that the disk was suddenly ejected.
The next day the disk was in the system, but after a reboot it disappeared. Subsequent reboots did not lead to anything - the disk did not appear.
The next day he appeared again. Disk Manager showed the status "Good (at risk)" (in previous days Disk Manager did not start). Moreover, surprisingly, both physical disks were shown for this array, and the remaining two arrays were shown as normal physical disks(one array - one disk). For the problematic array, the manager showed the type "Mirrored Volume", and for the rest, "Primary Partition".
After executing the reactivation in the manager, synchronization started and the volume entered the "Good" state. The next day the volume disappeared again.
The disk configuration is quite tricky. The motherboard has a built-in RAID controller. There are two Seagates of 80 gig each hanging on it. The system is located on these disks.
An external 4-port RAID is plugged into the PCI slot Silicon controller 24XX (I don’t remember the last two digits now). There are two WD 500 gigs on it.
To slot PCI Express A 2-port Silicon 3132 RAID controller is plugged in and there are two 320 gig Seagates on it.
Information about why everything works in this particular configuration has been lost for years.
Strangeness number one - this 3132 is not visible anywhere during boot and there are no invitations to enter its BIOS. Therefore, it works, in fact, like a normal one SATA controller, and his RAID array organized using Windows. If you go into the motherboard's BIOS and select boot priority, there will be four elements: built-in RAID, Sil24XX and two separate disks hanging on Sil3132.
Next, when the volume disappeared, an attempt was made to transfer the disks from two-port silicone to 4-port. They didn’t appear in the disk manager and AIDA didn’t see them either (I didn’t figure out how to go into the controller’s BIOS). After this, the disks were rearranged.
The disks appeared in the system when I reconnected the adapter IDE-SATA power supply to the other tail. Thinking that the power supply was to blame for everything, I left the server to look at for another day
We will call this configuration “control”
Today one of the disks began to make whistling sounds (like something clinging to the cooler). The intensity of the sounds was about once every 5 seconds. Sometimes stopping. At the same time, no manipulations were performed to access the disks. The server was running with the OS loaded. The system began to freeze, and then said that the disk was unexpectedly disconnected. In the process of searching for the source by sequentially disconnecting the disks, it was determined that this was one of the disks in the problematic array. But while they were looking, the second disk from this array stopped being detected.
The second disk appeared when the first connector, rather than the outermost connector of the adapter, was connected to it.
After looking at all this, I again restored the control configuration. Everything started working again without additional sounds.
Well, now the question is: who is to blame and how to diagnose it all?
I have three candidates:
1) RAID controller. But then why didn’t the disks appear when they were reconnected to another controller?
2) Disks. But then why do both disks disappear synchronously? It’s hard to believe that two disks have the same malfunction
3) BP. In principle, it should be enough. It's 420 watts. From the consumption of 2 xeons of 110 watts, 6 disks with a total peak consumption of 55 watts and two RAID controller. And if the problem is in the power supply, then why do these two disks fall off and always in pairs?
Yes, I already read today that Silicone and Seagate are not friends, but it worked for years.
In general, I will be grateful for any diagnostic ideas.
Best regards, Vasilisk
Answer: I forgot to write. The problem was resolved by replacing the power supply
Question: Transferring information to another disk.
I took an unnecessary 100 Gig disk from a friend and thought about finding a use for it. Since the disk capacity is small, I decided to use it either for a second RAM or... in short, I thought about whether it was possible to free up disk C (thereby increasing disk D), and all the information transfer to a separate disk. Hence the question arose whether this could be done and how to do it.
Answer: Mauritius
Of course, these are necessary questions. Since a free disk has appeared, I want to find a use for it.
And of course thanks for the advice.
Question: Hard drive disappears
The problems started after reinstalling windows7, before that the hard drives worked fine. I didn’t change any settings, I didn’t tinker with the hardware. After reinstalling Windows appeared local disk E (before that there were only C and D) and some information was copied to it from drive D. Windows moved to drive C, as planned. While working at the computer, it began to freeze and display a disk error on a black screen. It didn't show up in the BIOS. Turning the computer off and on helped. And all these dances were repeated for a month. Then I removed Windows, formatted the C drive and now I can’t install the operating system because the hard drive disappears before it is installed.
P.S. The computer has 2 hard drives.

Question: The disk structure is damaged and cannot be read. How can I save valuable information from disk D?
no access to D: the disk structure is damaged, reading is impossible - this is the message I received when I tried to access D..... After the computer suddenly turned off.
The W.Digital320 hard drive is divided into 2 partitions: main C: 50GB and logical D: 260GB... so the D drive has disappeared!
RAW file system. capacity, occupied, free - these are all zeros.
HP is installed on C, which loads easily.

Question: Inexplicable system slowdowns, Acer laptop e5-573g
Acer e5-573g laptop
Pentium 3556
8gb ram
The system is based on an Intel 530 120Gb ssd. Proprietary utility Intel SSD toolbox says the drive is fine.
Instead of the drive there is an SSHD ST500LM000 500Gb
Windows 10 Enterprise
Drivers are all updated to the latest versions.
Problem:
When opening my computer there was a delay in displaying content (about 3 seconds)
Initially, this laptop had a regular 1TB hard drive (not even sshd). After the purchase it was immediately replaced with an ssd. The terabyte unit fits into the drive slot. There were the wildest brakes when opening my computer (about 7-10 seconds), when opening drive D. Chrome started up for 10-12 seconds. The whole system was lagging. After replacing it with a 500 GB sshd it became better, but still worse than on the previous laptop (which had both an SSD and an SSD previously installed)
Help me understand what the problem is.
Either in the ten (the previous laptop had a seven), or in the disks, or in the integrated video card (which works when games are not running), or because the processor does not handle multitasking.
Betting seven is not an option because... bad people from Acer decided to release drivers only for Win 8 and Win 10. And on the seven without drivers it’s even worse than on the ten (tried it).
Linux is also a so-so option because... There is special software that is only available on Mac and Windows, but I don’t want to bother with emulators.
The previous laptop on the desktop worked perfectly, but it was just very outdated, weighed a lot, had a dead battery, and had lost its presentable appearance over the years of use.

Answers like buy a new hard drive are not needed. There is no money. I won’t take it for repairs either.
Answer: I completely disassembled the hard drive and reassembled it, cleaned it of dust. I'm glad that it at least turned on, because I took it apart for the first time. It makes much less noise and is not so hot now. I installed Victoria's remap for the night. Let's see what happens.

Question: I bought a used netbook, everything is fine with it, but it rattles a little, such strange sounds
Good day!
I'm far from a hardware pro, so I'm asking for HEEELP.
I bought a used netbook, everything is fine with it, but it rattles a little, such incomprehensible sounds. My old Hulett is 17 inches and it will be quieter.
The seller says that there may be problems with the cooler. but I’ve been reading your topic and thinking, “Or maybe a hard drive”?
I downloaded the program and tested it. Tell me from the pictures from the attachments (I thought I’d get old before I figured out how to load them)), what’s wrong with the disk?
Answer: Hello,
In principle, tapping and all kinds of clicks do not mean anything good. If the cause is the hard drive, it will subsequently lead to serious damage to the drive. But I see that the program did not give any errors. If you are 100% sure that the hard drive is knocking, then I would advise you to still try to test it again only using the utility from the manufacturer. And just in case if there is important information on disk, transfer it to another medium. Also make sure that the laptop cooling system is in good condition, try to remove dust from the processor heatsink and video card. Or better yet, just turn to specialists, they will quickly find exactly where the problem is and what needs to be done. I hope this was helpful, Citizen_WD
Question: C hard drive is there a problem?
Good night everyone.
Help me understand what my problem is. I apologize right away for writing a lot, but the problem worries me greatly.
This is the situation. I reinstalled Windows and at first everything was fine. But then the first freezes appeared. Then I decided to go to the Task Manager and see what the problem was. The hard drive was loaded at 100%, but besides this, the “Average response time” of the disk was either 30-50 ms, then suddenly from 2 to 20 thousand ms.
Then I decided that the disc was over. But I checked it with a couple of programs, and SMART was fine everywhere. I decided to connect another drive. But the same problem appeared there.
Then I decided to try the last option. I got it almost new hard drive from from a laptop. I measured the response time in advance, which did not rise above 30-40 ms. But there was a problem with the computer too.
So, besides, after returning it to the laptop, it began to load much longer, and the response often became 50 ms, and sometimes 200 ms.
There were also side effects.
Initially, I connected the drives with the computer turned off, but did not unplug the power cord and did not turn off the power supply using the button on it. And the first time you connect any hard drive, the computer boots Windows logo I just passed out. But on subsequent Windows downloads there was no such problem.
Then I thought, maybe it’s worth completely disconnecting the power supply from the power supply. I turned it off with the button on it. Next clicked POWER button to get rid of the remaining electricity in the computer. And after that I inserted the SATA cable. But then I went nuts, the computer simply refused to turn on, no matter how hard I pressed the power button. Moreover, if you leave it for a few minutes after connecting the disk in this way, it turns on successfully and there are no problems with further starts.
However, when changing the SATA connector, the problem with the first power-on remains. Another worrying issue is the response time. More and more often, a response time of 20 thousand ms begins to appear, and once it was 70 thousand ms.
Just in case I write:
1) I checked the 650W power supply with a multimeter (though without additional load in the form of a cooler or, as they say on the Internet, 5W light bulbs), all voltages are normal.
2) Tried to change RAM, the problem does not go away.
3) I found my old power supply (450W), fully working, but replaced with a more powerful one. There is such a situation: the problem with the inability to turn on the computer after a power outage has disappeared, but after the first connection the hard drive is still disconnected and the system still hangs, the response time is still very long.
4)Only when turning on Windows Everything hangs, the response is great. When the computer is idle, the response is small (sometimes it happens 0ms and the read/write speed is 0Kb/s). But when starting a serious program or game, everything may freeze altogether.
5) I read that the hang can be caused by the video card, I tried my old video card, the problem did not go away.
And one more small question: I have such a case that it is very difficult to remove the video card. It gets stuck somewhere in the grooves. Have to unscrew motherboard. And after that, press on the back of the video card, where all the connectors are. Sometimes you have to hit the back with your palm several times and only then does it come out. Could this method harm her? I checked her with OCCT, everything is fine and the temperatures are normal. So she's okay? And what's the best way to get it out?
Answer: Good night. Finally connected the drive, as you advised.
The following situation turned out: the first disk with the system refused to work, when I pulled it out there was a large crack coming from a hole in the center (When I inserted it, it was not there. Although I might not have noticed any small crack). But just in case, the disk is already old, I tried installing the system from another disk. From there, the installation booted successfully. True, I only got to the disk formatting window.
Does this mean that everything is fine with the motherboard?
The drive was really noisy, but maybe that’s because I’m already unaccustomed to it.
If it's not the motherboard, then I don't know what the problem is.
And can you tell me: if the problem is in the motherboard, then when I change it, will it be possible to connect the old hard drives, or can they just ruin the new motherboard?
If the flash drive cannot be formatted and there are no protective jumpers on it (such as against deletion), then most likely the flash drive is physically damaged - and then the solution is to buy a new one, they cost a penny. Because I already think there’s nothing that won’t help her, such as scandisks (error correction), etc., the only thing is if the flash drive’s company is loud, then try to format it with native software for it, if of course there is one.
The drivers can be removed from the USB.
The computer cannot find it and asks for a driver disk or to download from the selected folder. Probably this.
it happened, only formatting the card helped =(
Another option, there’s a little thing on the card that moves... the plug is so small... maybe that’s the problem)
It is better to destroy the compromised system (format the disk) and reinstall everything from scratch.
There is not the slightest guarantee that everything is truly cleared.
Think about what safety standards you neglected since a viral infection occurred.
In such cases, the Administrator is always and 100% to blame.
If it contains the necessary information - don't try to format it !!!
Apparently, the FAT (files allocation table) has crashed. Or information about sections.
Try to recover it as a whole disk first, using programs such as Norton Disk Doctor Active Partition Recovery
If you can’t completely revive it, then pull out the necessary data from it using programs such as R-Studio, GetDataBack
