DESPERATE - Failed attempt to Upgrade Basic to Dynamic Disk

Posted on 2005-05-15
Last Modified: 2009-07-29
Hi i've tried to upgrade a basic partition to a dynamic one to get mirroring working on a server..

I'm now receiving STOP: 0x0000007b INACCESSIBLE_BOOT_DEVICE when trying to boot the server normally or STOP: 0x0000006F SESSION3_INITIALIZATION_FAILED when I try LAST KNOWN CONFIGURATION.

Any ideas?

I've tried to boot to the 2000 Server bootable cd, and tried console recovery although the drives are not viewable.. When I open diskpart it says they are "Unformatted or Damaged".. Anyway to recover them?

They are not SCSI, or SATA drives nor are they on a raid controller, so I don't think it's a Driver Issue..

Please if anyone has any ideas!!

    Hi mortar,

     Lost, there is no way to recover the data now. And you will not be able to do mirroring without a raid controller that supports Raid 0,1

     There are warnings saying that data will be lost of this happens, and I am not sure why you would use a dynamic disk in the first place. The only reason I would ever use this is if the bios never supported this size HD in the first place.

    Accepted Solution

    Actually your data might not be totally shot.

    You should put the disk into another machine as a secondary disk and try to recover the data that way.

    If you have an additional HDD or equal or larger capacity and the right utilities, you could make a sector copy of the disk before actually editing it.

    Then you can use disk recovery software (there are tons of utilities that do this)  I don't recommend anyone specifically but I have had good luck with MediaRecover for what it's worth -

    Once you've recovered to another HDD, you can probably just format and reuse the original disk.  You could also try (just to confirm recovery of  all files) to activate the original disk with disk manager in the system in which you've recovered the data.

    Good luck.

    2 more tips:

    Also, you might want to check the jumpers and set the read/only jumper if it's available, before you install the disk for recovery just to make sure that no further damage arises.

    Also, it's a good idea to make sure that you are running an up to date anti-virus package on your recovery macine.

    Hi guys, thanks for your speedy replies..

    I fixed the problem by putting the drive into another computer, and converting the dynamic disk back to a basic disk!thankfully that worked fine, no data lost..  I then converted back to dynamic again and everything was perfect.

    I used this page:

    cyberdevil67, I beg to differ, software mirroring is possible using dynamic disks, that's why I upgraded the disks from dynamic to basic, to use this functionality;en-us;302969&sd=tech

    If you review my initial post on this question, you will find that the solution posted by mortar was what I suggested.  I believe that I merit some points for this response.  Thanks.

    whoa sorry Chipm0nk I was actually cleaning up all my open questions somewhat quickly and hastily and I missed that. I wouldn't have come to the answer I did without your suggestion to put the machine in another drive! My apologies!
