EaseUS partition manager terminated abruptly, leaving HDD partition to be unusable

Question

I was using EaseUS partition manager to extend my drive's capacity by including a 100GB partition into it.
The drive was earlier partitioned as 100GB+831Gb = 1TB(Toshiba HDD) and I was making it a single partition.
But during the process which was taking fairly long to complete, the power went off and it terminated abruptly.
Is there a way I can recover contents of the drive as they were?
I have already tried testdisk, but in vain!
The other option is to try a file recovery software but it will take weeks to sort out, with no guarantee that I will get back all my files! :(

Answer 1

You could try testdisk again but with more "tricks", the help pages have several examples, see the "Documentation" section here: http://www.cgsecurity.org/wiki/TestDisk

And if recovering the partition / filesystems doesn't work, then PhotoRec can recover lots of different filetypes. It's by the same author & in the same package as Testdisk: http://www.cgsecurity.org/wiki/PhotoRec

There's other tools like Scalpel, Foremost, MagicRescue too...
