After formatting, those tools can often be quite successful.
However....getting back LARGE things like movies all in one piece is nearly impossible.
If you tried Recuva, etc...and it didn't work, the only recourse is to pay someone $$$$
Yeap, that was my guess as well. But after some research I found that these people you pay money to recover your files use some kind of a device to do the magic. They plug your hard drive to this device and the files come back. If you have any info about these devices, can you please tell me what they are called or if they are obtainable?
The hardware for imaging unstable drives is only relevant to physical drive problems(and for write-back protection).
Recovering large files after a reformat is difficult and time consuming for a different reason and simply requires expert knowledge in identifying, carving out and piecing together the fragments of the file when file system information marking the locations is missing(due to reformat).
As long as the engineer has a lot of experience, getting back playable data is still very possible just also very costly.
Good news is there are a few reputable companies out there with no-data, no-charge guarantees and high success rates.
For example there is ACE Data Recovery, which is who I would recommend.
Check the WD data recovery support site for a more comprehensive list.
