Hello, I have just run "Paragon Hard Disk Manager 12 Suite" from administrator on a 10+ year old WinXP SP3 computer. I used the "Express Resize" option to move about 10GB from the C: partition to the D: partition. Before___________:___ C: 68 GB ___ D: 81 GB Intended Result__:___ C: 58 GB ___ D: 91 GB After "Apply" the computer restarted and the operation proceeded pre-windows resulting in a bad block (or sector?) warning. I heeded the warning and opted to cancel the operation, however after login to WinXP the D: partition has been erased, and the C partition now shows 58 GB. There is an unallocated 10GB partition above this. Actual Result____:___ C: 58 GB ___ Unallocated 10 GB The Undo option is not active. Is there any way to undo this operation and restore the D: partition ?. This is not critical, it is a backup computer and I can rebuild the data on the D: partition from another computer, however I would like to know if the partition is recoverable for future reference. Thank you.
