Some disk drives can be picky like that. I had one that did not like some Memorex media.
I re-flashed the firmware couple times, seemed to help temporarily, only to relapse after a while. If you want to try this, make sure you research about the firmware for that particular model, as you could easily brick the drive if not done right.
I ended up replacing the drive with a different model and didn't look back. Of course, I "had" to flash a region-free firmware on the new one, just to make it 'better". That ability was one of the criteria I used when choosing the replacement.
