It's strange that only jpg's are unreadable.
How many jpg's have you checked ?
Whats the ratio of damaged pictures (of all pics)?

That's odd. Should be the reverse way, damaged movies and good pics.
How many partutions did you had before? How many after? Where the pics in the same place as the movies?

  • Can you confirm that you are working off a clone of the drive and that you were not writing anything further to the drive from which you are trying to recover from?
  • What was used to format the drive?
  • When the drive was formatted, was that all that was done?
  • What file system was it before it was formatted?
  • What file system is it after?
  • Was there anything written to the drive after it was formatted?
  • If data was written to the drive after the format, how much data was on it before? How much data is on it after?
  • What program(s) were used to scan and recover the data?

well a laptop with Win Vista NTFS was formatted a month ago by a guy who didn't have back up. he installed WinXp in NTFS partition again. he also installed a few programs. after he relised he lost his files he installed 2 progs: getdataback from NTFS and recover my files. the results were catastrofic, because the files he found (which where useless -about 250 dir with bad staff-) he saved them to the drive.
and after this he brought it to me!
so i tried with Easeus Prof recovery tool. i found the My Documents Folder which was the only one needed. its about 7Gb of data. and 3Gb of photos. all the files are good ecxept from the photos.
So i will try what ththeod said and i will let you know.
thank you for your help

Just as I thought. The XP foot print would certainly be smaller than the Vista footprint on the drive, but it likely overwrote some of his data. The installation of programs overwrote more. The scanning of the drive (likely caching to the drive during the process) overwrote more data...then the coup-de-gras, by recovering data to the same drive you are recovering from. As you are reading a file, you are overwriting the contents of another, but the recovery program doesn't know this and thinks it is reading the contents of the file that it originally found.

Here is a simple example (very simplified)

Sectors before a recovery:
0123456789

Read the first sector and write it to the next available space:
0023456789

Read the next sector and write it to the next available space:
0003456789

and so on, until you get:
0000000000

Of course, instead of single numbers, you are writing chunks of data, but are likely going to see the same pattern continuously repeated throughout the drive.

So, to sum it up, the data was shredded and is unrecoverable.

I had good results recovering corrupted images with Active@ File recovery. Did encounter something odd though, which might have something to do with a problem I experience with my own disks. If I try to recover entire directories (containing images), the recovered images will also be corrupted. If I recover all files from a specific directory (selected files), they will be recovered as they were originally.

Before, I had good experiences with GetDataBack as well before I had a bad experience (files he couldn't find although they were there). I then switched to R-Studio for NTFS. But in the issue I am experiencing now the latter does not help; all files it recovers remain corrupted...

The files aren't corrupted, they are overwritten and toast. There is not software tool out there that is going to reverse the contents of each sector that was overwritten.
