Dynamic Disk back to Basic Disk?

#1 Post by aligator638 » 02 Feb 2014, 03:53


Like many people, I made the mistake to try to extend a partition on my RAID5 drive (hardware) and ended up with a dynamic disk I do not want and would like to revert to basic disk and standard partions. I found out about TestDisk, and would like to know if this is the right tools for the job.

One of the problem I see is my F: partition is split in two areas of the disk. will converting back to basic "consolidate" it into one basic partition ?

Do I need to shrink (by removing some file and using the windows disk manager to shrink it) back F: (I can backup L: T: to an USB drive temporarily) such a way that it becomes contiguous before using testDisk ?

OS is Windows 7 x 64 (so TestDisk x32, I guess ?)

It's possible to convert an accidentally converted disk, back to basic/MBR-disk
But testdisk won't consolidate any partition back.
In case it's recommeded to backup your data first.
If your data from your F-Partition are not accessible, you can have a try to list your data using testdisk and copy them.
MBR partition structur can only contain 4 primary partition or 3 primary and 1 extended for your logical partitions.

Please repeat your diagnose and copy and paste the content of your testdisk.log into your next post.
Intel-MBR doesn't support any spanned or splitted volume.
That's why a backup of all data from your spanned or splitted partition is recommended.
