How to Repair a Corrupted SD card / USB Hard drive

If your PC does not detecting your SD card or USB flash drive and you are thinking of buy a new one, just wait and try this before spending bucks on the new one. When we inserted a corrupted flash drive into the USB port and try to access it, it shows an error like this:

                 You need to format the disk in drive before you can use it.

When you click on the Format Disk and start the format, it displays the following error:

  Windows was unable to complete the format.

Windows was unable to complete the format
windows cannot format drive

If you also have similar kind of problem with your SD card or External hard drive or USB flash drive, then keep reading. I am going to demonstrate a method to fix corrupted storage devices. The windows was unable to format the disk because it has no specific file system (e.g. NTFS, FAT) associated with it. This drive is called RAW drive and it can be repaired by formatting the disk.

NOTE: Before moving further, please note that this will remove all data from your SD card/ flash USB drive permanently. If you have some important data, you can try some hard drive data recovery tools before trying this. There are many hard drive recovery softwares available for free which can recover data from USB drives and external hard disks.

Before trying this method to repair your SD card, I would suggest you to try my previous method as it is easy and safe to perform. If that not work for you, you can come here and follow the below steps. Here is the link to my previous post.

Windows Was unable To Complete The Format-How to solve this

How to Format a Raw SD Card

If you are sure you do not have any important files on your drive and want to repair it by formatting, follow these steps:

1. Plug your drive into the USB port of your PC. Make sure only the damaged / corrupted SD card or USB flash drive is connected to PC and remove any other removable storage devices.

2. Then Open the Computer window and note down the drive letter. As you can see in my case it is D .

3. Press Win Key + R to open Run box and type cmd. Hit enter and Command prompt window will launch. You can directly open command prompt by using the shortcut Win key + X and choosing Command prompt.
run command
4. Type diskpart and press enter. An warning message will show up, just click Yes and a new command prompt window will open with heading DISKPART. Now, you need to type all the commands in this window. 

5. Type list disk in order to list all the disk drives connected to your System. Detect your drive by its size as one will be of huge size(your Internal hard disk) and other will be your SD card/ USB flash drive. That’s why I asked you to remove all the other drives from your system.

corrupted hard disk recovery

6. Next, you need to choose your corrupted disk drive. Perform this step very carefully because if you select the wrong disk number by mistake, it can remove all the data from your internal hard disk. Type select disk “your disk number” . As you can see, In my case it is Disk 2 of size 8 GB, so I will type select disk 2 and hit enter.

7. Next type clean and a message will displayed that Diskpart succeeded in cleaning the disk.

8. Next you need to type the command – create partition primary and hit enter. A success message will be displayed.

9. After this type active and hit enter.

10. Now you need to execute the command select partition1

11. Finally, we are going to format the drive with file system FAT32. So type format fs=fat32 and press enter.

external hard drive data recovery

12. It will start formatting your drive. It will take quite a long. Just minimize it and wait for format completion.

When the format completes (100%), close the command prompt window and go to Computer in order to check the drive. Verify your drive by copying some data in it.
By this method, you can repair your corrupted SD cards, USB flash drives and even your External hard drives. Again, after performing above steps you will lose all your previous data. So, if you have some important data in your drive, try to recover it first using hard drive recovery software. Here is the summary of all the above performed operations in order:

-diskpart 
-list disk 
-select disk ‘your disk number’ 
-clean 
-create partition primary 
-active 
-select partition 1 
-format fs=fat32

Hope this help you in repairing your corrupted SD card, hard drive or flash drive. Let me know whether it worked for you or not via comments.

    • siti

      i get same answer with you..what should i do?

  20. Amar pawar

    This means that your SD card does not have any file system associated with it. Try this- Open command prompt and type:
    chkdsk D: /f
    Replace D with your Drive letter.

    • KB

      @Amar pawar: I did exactly what you said above for my 2GB Sandisk microSD card that is in my D: drive slot (for SD cards) – chkdsk D: /f
      It said: “The type of the file system is RAW. CHKDSK is not available for RAW drives.”

  21. Amar pawar

    yea, it don't matter. Actually, previously your hard disk has file system NTFS and now you are going to format with file system FAT.

  22. Razvan Leuciuc

    How do i do that ? and what disk … i have a stick …

  23. ShutUpHooker

    When I go through the clean command, my 32gb SD card unmounts/disconnects from the computer as soon as "DiskPart succeeded in cleaning the disk" is done so you can't go any further [it no longer shows up in list disk]… what does this mean/? I have to remove then reinsert the card and all data is still there, can't format like before cant' erase/rename any file? Can't do anything … thanks for any help [PS my screen name is about rugby, not anything else!… lol]

    Sir
    When i type create primary partition, it says "No usable free extent could be found. It may be that there is insufficient free space to create a partition… the disk contains either 4 primary partitions, (no more…) or 3 primary partition and one extended partition, (only logical drives may be created).
    i am working this on my 16gb sandisk micro sd card (instead it is showing only 8 mb when i type list disk)
    I have read the previous comments but nothing did help me.
    please be kind enough in resolving this for me.!

  34. Arpit Murkya

    @Abbhinav.. has your issue been resolved.?
    Do help me if yes.
    @Admin(Aman Pawar).. please reply to my post..i need to use my card urgently..
    thanking you in advance

  35. Amar pawar

    Try this – Go to Command Prompt and type chkdsk D: /f /r (Here D is the affected drive)

  36. Ryan Matthews

    for anyone with the

    ."No usable free extent could be found. It may be that there is insufficient free space to create a partition at the speciffied size and offset. Specify different size or value or don.t specify either to create the maximum sized partition. It may be that the disk is partitioned using MBR disk partitioning format and the disk contains either 4 primary partitions or 3 primary partitions and one extended partition "

    i found a simple work around. when you're getting that message try these commands;

    list partitions
    select partition 1

    then continue on from the "active" command step (step 9)

    I have an 8GB sdcard that was previously setup for a Raspberry Pi with the NOOBS software. I went through the steps outlined here with no errors encountered. Using Windows 7 I copied my NOOBS files over to the "clean" 8GB partition and popped it back into the RPi2 and booted it up. However, I did not get the option of installing multiple OSs as I would expect, so I abandoned the install. It appears that the original MBR is still intact on this sdcard and is trying to boot into some sort of recovery mode. On inspection the sdcard now has 3 partitions one has been named "Recovery". How do I wipeout the original MBR? Or is there something else I'm missing?

    i am unable to do the step "create partition primary"
    when i given that command it is showing " unable to create partition primary due to insufficient storage"
    as my SD card is 2 GB, but it is showing only 30 MB.
    pls suggest me some other method.

  52. ShutUpHooker

    I think its pretty clear by now that the person who started this doesn't know jack shit about repairing a corrupted USB/SD/HDD … from what I've read its usually a physical damage to the unit and no longer repairable, copy any documents off and call it a loss

  53. Kartikeya Jain

    the size of the pendrive is displayed as 5632B whereas its is a 4GB drive. secondly, on giving the "clean" command, an error message is displayed – " The semaphore timeout period has expired. See the system event log for more information"
    What to do?

  54. ShutUpHooker

    What you do is take that 4GB hard drive, place it in a blender and hit the button that says "frappe" and then buy a new 4GB stick

  66. Jason Reuber

    for those who have tried this and other methods with no success i suggest you check out recoverfab.com. my 32gb micro sd in my samsung note was accidently formatted and after the format became corrupted somehow. i tried every method imaginable to recover my data with no luck whatsoever. i must have downloaded and ran over 30 different recovery programs (easeus, recuva etc…) and most wouldnt even recognize the card at all. chkdsk showed it as raw so i tried to reformat the card and windows couldnt even detect it. showed 0 bytes used, 0 bytes detected. after scouring the web for days and endless frustration i learned the card was most likely physically damaged. i contacted recoverfab about my issue and they replied right away with a quote and how to proceed. i went down to ups and mailed my card away (from oregon to germany so it took about a week) they were able to recover %100 of my files and the whole process was rather quick and painless and priced quite reasonably. i tried to find a company in the u.s. who did this and none i contacted could do recovery on a micro sd card.

    Hi,
    I was able to follow all the steps till "create partition summary" where it said "No usable free extent could be found." I have an 8 gig microSD so I'm not sure what's happening. (It also initially said the size of my microSD was 30mb under "list disk" when it clearly is not.) Maybe it's time to get a new SD card?
    Thanks anyway.

    Your suggestion to recover from RAW worked on my 1tb disk. I followed your instructions up to the point of selecting Partition. Saved my 1tb disk that had been causing me many hours of trial and error to format. Thanks for your information.

    Hi. Sorry but diskpart can't detect my SD card but was displayed on drives in Windows Explorer. When I try to open it, it says "Please insert a disk into drive (F:)"

    DISKPART> create partition primary

    No usable free extent could be found. It may be that there is insufficient
    free space to create a partition at the specified size and offset. Specify
    different size and offset values or don’t specify either to create the
    maximum sized partition. It may be that the disk is partitioned using the MBR di
    sk
    partitioning format and the disk contains either 4 primary partitions, (no
    more partitions may be created), or 3 primary partitions and one extended
    partition, (only logical drives may be created).
