Has anyone noticed problems on the ND3520 with minus R media since changing to the latest firmware? See images below; two on 3.06 written at x4 I think, two on 3.07 written at x4 and x2 (all 4 discs from the same spindle, I stopped the scan of the bad one in the middle because it was pointless to continue).
Either that, or the drive mysteriously decided it stopped liking -R during the 2 months between the writes. I find it hard to believe it’s the media to blame, judging from the error pattern and the fact it’s the very same spindle.
Also, is this NEC drive (and close models) bad in general when it comes to writing (or reading or both) -R media? The “good” scans below are what I get with -R media (which I generally don’t use), which is quite out-of-spec.
