Nero or my NEC 3500-AG suddenly won't burn discs anymore

[Leander]

So I was in the process of backing up a couple of new movies I purchased and when I got to the second disk I received the following error:

Burn Process Failed at 6.1x (8,418 kbs)

1:30:10 DVD-Video files reallocation started
1:30:10 DVD-Video files reallocation completed (no file modified)
1:30:10 DVD-Video files sorted
1:30:10 Caching of files started
1:30:10 Caching of files completed
1:30:10 Burn Process Started at 6.1x (8,418 kbs)
1:30:10 _NEC DVD_RW ND-3500AG Illegal Disk
1:30:10 _NEC DVD_RW ND-3500AG Could not perform start-at-once
1:30:10 Burn Process Failed at 6.1x (8,418 kbs)

Anyone here familiar with this kind of error?

[ROF]

Quite familiar.

It's called bad media. You may go through several spindles of the same media without error until you try the one(s) that is/are bad.

wow, never had that problem before and I've burned probably close to a 1000 disks. I wonder if Best Buy will exchange my bad spindle for a new one

edit: looks like you're dead on, I found an old disk I never use before and tried using that one with no problems
