Many years ago I converted all our home videos from VHS to DVD. We made about 6 copies for various groups of family members, and they're spread over 7 or so DVD Videos (with menus/chapters, etc). The original transfers were far too huge at the time to keep, but I kept the Nero "NRG" image files.. until the other day, when I accidentally wiped the hard-disk they were stored on.
Since then I've been trying to get the data off the disks - I have 2 copies of each disk with me.
- I tried 2 Mac's, one running Mac OS X and another running Windows, but they kept tripping over during file transfers, and I had to restart and hold the click button to eject the CD.
- So I'm now trying my blu ray drive at home. It seems as though in both copies of each disk I have, the SAME files or parts of files are corrupt. But if I cancel the transfer at the point in which it can't read from the disk anymore, I can still open the corrupt file and watch some of the footage.
- I used ISOBuster to try and recover the data. It quickly found corrupt sectors and I opted to 'skip' all the corrupt sectors - however it still reaches a point where the entire system halts and goes *extremely* slowly, with ISOBuster appearing to not respond and stuck on the same percentage.
- The weird thing is, I found that if I let the computer eventually put itself to sleep, then wake it up again, it kicks ISOBuster back into action and it manages to copy a significant portion of the file before tripping over again. Overall however, it's a tediously slow process.
I'm just wondering if anybody has had a similar experience and can shed any light on what might be happening, how I might be able to recover the data, and why the same parts of 2 copies of a disk are corrupt..
