A simple "un-delete" proves very difficult

[m1tch37]

I had a folder on my iPod which contained hidden files. I foolishly assumed it was empty. As I hit the delete button, I was instantly alerted when it said "deleting 56Gb". I hit cancel asap and saved most of the files, however some critical files were deleted. I put my iPod in Disk Mode right away and didn't write a thing to it. One would assume the files are still there.

I have tried now four different recovery software packages, including Recover My Files, and they have all reported all sorts of junk, just not the three files I want. One (ZAR) was able to find about 30% of the files.

How can this be!? Nothing has been written to the drive, how could I have lost 70% of the data like this after a simple Windows delete action (was running for <1 second)

How can I recover this information, what software do I use?
Thank You

(Note: FYI these aren't files related to iPod_Control, they are personal files I had hidden, it is absolutely unrelated form the iPod itself)

What type of files are they?

[m1tch37]

TrueCrypt partitions, each 4Gb in size, with no file extension.

What I just can't understand is they couldnt have possiblity been written over, as soon as they were deleted I didn't touch the iPod. They MUST be recoverable, I just can't work out how...

Try running a Complete Format Recover on on the physical drive and search only for the default selected file types. At the end of the search look in Folder View of the results screen for your missing files.
