How to recover from Bad relative sector and Space Conflict?

#1 Post by BobW »

I had two identically formatted NTFS 300 GB drives, L: (dev/sdc) and M: (dev/sdb). USB 3.0, Windows 7 / 32-bit. Drive M: is still fine, but after attempting to use Lenovo Rescue and Recovery to back up drive C: to drive L:, I almost immediately got an R&R "internal error" and terminated the program. At that point, L: was no longer usable.

TestDisk Scan and deeper scan show no partitions found. :cry:

I would like to recover the partition table and file system of drive L:, but I don't know how to proceed given the errors logged below. The log shows both the bad (L:) and the good (M:) drives, for reference. Windows disk manager shows the L: drive as correct size and "healthy" but "RAW". FYI, both 300GB eSATA drives are connected to a Thermaltake BlackXDuet (dual drive) external USB device via a common USB 3.0 cable.

Log follows. I think I interrupted the scan in this run, because it took a long time the first time, and I forgot to turn on logging before I ran it. I can re-run both scan and deeper scan again with logging on if still required, but the first time they showed no partitions found.

TestDisk exited normally.
Any hope or is file-by-file recovery via PhotoRec my only option at this point?

Re: How to recover from Bad relative sector and Space Confli

#2 Post by BobW »

Problem resolved, all files recovered! :P

My big mistake was in Partition Table Type selection. I was always moving the cursor from None to Intel. Today I found another post with similar error messages, and a suggestion to just leave the selection at None and just press Enter. Then TestDisk immediately found the NTFS partition and reported Boot Sector: Bad, Backup Boot Sector: OK, just as shown in the example in the step-by-step tutorial, under NTFS Boot sector recovery (http://www.cgsecurity.org/wiki/TestDisk ... r_recovery).

I pressed Enter again with Backup BS highlighted to restore the boot sector from the backup, quit TestDisk, restarted Windows 7, and everything is OK! CHKDSK reports no errors.

Thank you TestDisk! Full disk recovery has to be the best Christmas present that I'll get this year! :D
