Dvd-R Disc

[Arti]

I recently bought a new computer. I backed up my files etc onto a series of DVD-R discs. I've managed to re-install all of the files onto my computer, except for one disc's worth. My computer doesn't acknowledge that there is a disc in the player. I've also tried on my work computer; that's the same. I need the files on this disc. Can anyone suggest anything? Thanks

Can you not now reuse one of the other discs to copy the info onto?

1) Always "test" a CD or DVD before destroying the files on the computer.

2) It is probably best to also backup to an external hard drive next time (AS WELL AS ON DVDs)

It sounds as if your disk is corrupted. I assume you have tried cleaning the disc.
This may do the trick - be prepared for it to take hours.

Windows looks for an 'index' file on the disk. If it can't find that, it will either see a disk as being empty or simply refuse to accept that it even exists (even though all other files on the disk might be perfectly OK).

Try Recuva first (because it's completely free):

If that doesn't work try the free trial version of the mighty IsoBuster. (If that program can't solve your problem, I very much doubt that anything can):

It's a while since I needed to use IsoBuster (but it's certainly solved plenty of problems for me in the past), so I can't remember exactly what the limitations of the free version are. However I suspect that it will do everything that you want, without having to pay (US$39.95) for the full version.
