How to recover partition(s) if sizes don't match?
Posted: 29 Apr 2016, 21:38
I've had a disk failure on a 1.5G Windows 7 drive. I used ddrescue to recover all but 181K to a 5T drive (not to an image, but directly to the device.) I then used ddrescue again to copy from that device to a new 3T internal drive, but ctrl-C'd out when about 2.8G had been copied, since the original drive was only 1.5G. (Probably not a genius move.) The partition information is corrupted, either due to the original drive failure, or my clueless attempts at recovery. There were 3 partitions, a Dell Utility partition, a recovery partition, and the main partition with the files I need. They are listed when I look at either the recovered drive or the new drive with Ubuntu Rescue Remix 12.04, but I haven't gotten anywhere with fsck or chkdsk.
I am now using TestDisk to try to recover the partitions on the new drive, but Quick Search said it couldn't recover any partitions because the size it scanned on the new drive (3T) did not match the size of the recovery drive (5T). Deeper Search is running now but I assume it will fail the same way.
Is there anything I can do to fix this and recover the partition(s)? TestDisk doesn't seem to have any params that sound helpful, so I'm not sure what to do next. Should I just give it up and use PhotoRec to recover the files? Or should I try using ddrescue to recover the failed drive a second time, this time to an image file?
Thanks for any help!
