Data Recovery and Disk Utilities Forum @R-TT

I am trying to recover some videos from my nas. I have scanned the hdd and I can see the complete folder structure all intact as in before the error.

I can recover my mp3's and other documents fine.

But when I come to recover my video files a large majority of them recover fine but then do not play once they are recovered.

Can anyone help?

Cheers.

What is the type of NAS? And what is its file system? ext2/3fs?

I have exactly the same problem. The disk come from a QNAP NAS (TS-109), formating in ext3 or 4 I guess.
All the files recovery went fine, except for large video files (700 Mb and over) that are not playable anymore once recovered.
I used a windows computer to access the disk and I copy them on my QNAP (wich has a new disk inside).
Has anyone an idea to recover the video files ?
