I have an external 1TB HD that was previously formatted with NTFS and then given to a Mac user who, probably, formatted it with HFS+, filled it with data, and then ... BOOM. Nobody can tell what happened.

My best guess is a partition table corruption, anyway, here is what I've tried:

  • EASEUS Data recovery, partition recovery, who did a good work in finding delete data (there was everything visibile after the process). The only problem with this solution is that it would have took 30 thousands hours to complete. I have no idea why.

  • TestDisk, who analyse function took 6hours to complete just a 04% and then I had to stop it.

  • Active@ Partition recovery, whose result is here: http://img39.imageshack.us/img39/6324/immaginecst.png

are you trying to recover data that was on the drive when it was NTFS. Or what the mac user was using? –  Journeyman Geek Nov 2 '12 at 8:03
    
NTFS partition is gone after the mac user formatted the hard disk with HFS, but it is my guess! I mean, i have no idea what he did to the hard disk. I'm trying to recover what he loaded on it, not the NTFS –  Dario Nov 2 '12 at 8:07

One issue you will have is that Windows can't natively read HFS+ partitions - so even if you can re-create the partition table, you won't be able to recover the data directly. There are several apps (paid and free) that can read HFS+ on Windows - macbreaker.com/2012/02/… –  PJC Nov 2 '12 at 8:33
    
i'm already using HFS explorer,but it doesn't see any partition. What about some unix tool? –  Dario Nov 2 '12 at 8:57

Sounds to me like the drive has catastrophically failed. –  CharlieRB Nov 2 '12 at 13:51
