slow recovery of PDFs & perculiar errors
Posted: 28 Jun 2014, 22:24
I've been using Testdisk for some time now to recover drives in various states. It has always been my go to app to resolve issues.
This one is bugging me a little though. I'm working on a 1TB drive with about 300GB of data on the drive. It's formatted as NTFS, Windows pretty much hangs when its connected by USB (its native USB). I tried running chkdsk /f d: but that seemed to hang as well, so Windows wasnt playing ball. Linux however seemed to run ok with the drive plugged in, but it wouldnt mount - citing an IO error of sorts, and also saying there was an error in the upcase table. Weird.
Testdisk however lets me list the files on the troublesome drive. I'm in the process of copying the files to another drive, but it literally is taking forever. I dont know why. Previously this may have taken up to a day or so with a large amount of data, but I've been running this for nearly a week and I'm probably not even half way. A lot of the files are PDFs - do these take some time to recover or is it more related to the drive issues?
Every now and again I get a message in the Testdisk window saying:
I assume this means that for a split second Testdisk lost access to the drive but then resumed it somehow?
I also get
Anyway - the MBR on the drive and the MFT seems in tact, I cant understand why it wont mount, it takes an age to image with ddrescue (running at about 4kb/sec if I'm lucky) and Windows doesnt want to play ball. Any tips to speed up getting the data out would be appreciated?
Cheers
