Simple Fix! “the disk structure is corrupted and unreadable ” – Disk Management

05 Apr

Recently I had a problem which was very frustrating. While in disk management, I was was trying to initialize an iSCSI disk. Every time I tried, it would throw the message “the disk is corrupt and unreadable”. I found the solution and it’s too easy to not share.


I found the fix here: Windows Server 2008 installation fails with “The computer could not find a valid system volume”

  1. Start out by logging into your server
  2. Run “Computer Management ” (Start -> Administrative Tools -> Computer Management)
  3. Check out “disk 3” in the image below. As you can see disk 3 is offline.
  4. If you click “Online” it throws this box:

Solving the Problem:

On your host.

  1. Start up the command prompt and run the following commands:
    san policy = OnlineAll
    exit diskpart
  2. In Computer Management -> disk Management, right click on the Disk that is giving you  problems -> properties
  3. Write down the location of the Problem disk
  4. Open Device Manager -> under Disk Drives
  5. Find the Problem disk by location comparison
  6. Once you find the Problem disk -> right click and uninstall
  7. Open Disk Management -> right click -> rescan
  8. Initialize your disk’s now, they should work!

      This is a different type of problem I believe. I looked up your problem and I think it is called a “blackout”, it has something to do with bad sectors on your disk. There is a way of recovering these sectors, this can be done with a program called TestDisk. The documentation for Test Disk can be located here Step-By-Step. If this doesn’t work please contact me again and we can find other methods.

    Thank you, it worked.
    I recommend not restarting after uninstalling the drive – go straight to disk management and rescan.

    Hi win1337ist,

    I am using a Seagate 1TB external expansion hard drive. I have over six years of data saved on that drive. Recently I am getting the same error. I followed the TestDisk Step By Step document. But that didnt help… I am using Windows 7 Professional x32-bit. I tried the quick search as a deeper search. Is there any way to recover my data. Any help is much appreciated. I dont screenshots now. I will try the TestDisk again and snipe the steps followed.

    Thanks in Advance

    I have fixed the issue. I just tried the very basic step and that seem to fix the issue. I ran a check disk for the drive under concern and that made the drive accessible.

      Hey Maheswaran,
      Thanks for the update, i’m glad everything worked out for you. Try to make backups in the future to eliminate losing your data.

        Thanks win1337ist,

        The funny thing was the data on drive was actually the backup. I noticed the issue when I tried to restore it from backup.

        Anyway everything worked out well..

        Thanks again.

    Had this issue a few month back with my CDROM Drive. Found this article, Followed the instructions, and BAM it was like Gandalf had dropped some magic on my PC,.. everything went to working again. Today,.. nothing. Same issue. Same Error as described. Tried this fix again,.. nothing. No disk will read in the CD Drive. Any ideas?
