I've just gotten a Samsung DVDRW (detected as TSSTcorp CDDVDW SH-S203N) ... but it's unusable. The drive seems to be detected, but it doesn't read anything and when I try to write anything with it, it locks the system up. Locking also happens during install making it impossible to use the drive for installation. I had to use an older LITE-ON DVDRW to install Kubuntu 8.04. This was also happening with 7.10 with the same drive. I haven't found anything on Google or in this forum about this problem so I'm guessing I'm just special. Anyone have any ideas?
