Hard disk partition not found

#1 Postby jrcoop » 11 Jul 2012, 17:46

Running Windows 7 pro 64bit OS. Had a data-only NTFS 1TB HD fault while copying a large number of pics (no backup – lesson #1 learned). The disk had disappeared from windows explorer so went into disk management and saw the disk … at this point I was presented with a choice of MBR or GPT to initialize the disk … and I chose GPT (it was late and I was not thinking very clearly … excuses, excuses). This left me with an unallocated disk, at which point I stopped to rethink my actions. After trying numerous partition recovery programs without success – they could never find the partition – I suspected that having the disk as a GPT might be the problem and used the DISKPART command to try and convert the HD to MBR, but that didn’t seem to make any difference. At this point I’ve come to the realization that I’m in over my head and need help! I’ve run TestDisk through quick and deeper searches and include some screen captures here. The testdisk.log is very big so I hesitate to copy it here. Looking for guidance on how best to proceed.

More info - here's the first part of the testdisk.log (as I said in the first post the whole log is very large - approx 311KB of text ... many many pages):

Re: Hard disk partition not found

#3 Postby jrcoop » 13 Jul 2012, 19:31

Yet more info - screencaps from CrystalDiskInfo and Restorer Ultimate - which found 146 NTFS partitions, each one a different size and in total far larger than the 1TB capacity of the disk. Also found 81 HFS+ partitions ???

The disk had hundreds of JPEG images from an 18MP camera, so each JPEG averaged around 5MB - I could find some of them in Restorer Ultimate but was unable to preview any of them.

Any help would be greatly appreciated!

Please take a moment to at least tell me if there's any hope for recovering two years of my life in pictures. I'll gladly add whatever additional information is needed - though I've apparently used up my attachment quota in this thread. Really don't want to spend hundreds of dollars on a recovery service if there's a way to do this at home. Thanks.
