Hello All,

I am using Acronis Disk Director 11, Home edition, which I purchased roughly a year ago (this is my first time using it).

During an install of Windows 7, I destroyed the partition of a spanned dynamic volume that had the volume information stored. Now Windows 7's Disk Manager shows these physical disks as invalid. Acronis Disk Director is able to see and extract files from within the program, however, I don't see how to repair/mount this spanned volume. The logical disks belonging to this spanned volume are labled "Simple/Spanned; Healthy".

Is there a repair function, or am I doomed to try and copy 12TB worth of data to somewhere else and recreate the spanned volume?

Thanks.

Will DD allow you to copy the volume?

Will DD allow you to resize the volume? If it will, I wouldn't try it without a backup.

I would recommend that you use whatever method you can to copy the data off. As far as I know, you can't use DD to "repair" a Dynamic Disk. Also, any repair attempts you do try may cause further problems and could cause more data loss.

There was nothing to "repair" other than writing the system volume information to the boot drive.

Since that didn't seem to be an option anywhere that I could find, common sense caught up with me... if I resized a partition (in my case the boot partition), then the system volume information HAD to be rewritten to accommodate. So I took the boot partition and resized it from 1TB to 999GB (there was only 45GB of data on this drive).

I rebooted and VIOLA. My data was accessible again.

It seems to me that this is using existing functionality in an non-obvious way. This is pretty much always a faux pas.

Either way, I felt pretty safe about the operation and it worked. Hopefully this will help anyone in the future.
