I've wasted lots of time with SATA DVD drives recently (specifically
with DVD-RAM), but I haven't got any answers (yet) -- I suspect that
SATA optical drives have not yet 'matured' under Linux.
Initially I had an LG GSAHN30, which worked most of the time, but would
randomly not read disks, and eventually started putting messages like
ata3.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x0
ata3.00: (BMDMA stat 0x6)
ata3.00: cmd a0/01:00:00:00:00/00:00:00:00:00/a0 tag 0 cdb 0x2a data
131072 out
res 50/00:03:00:00:00/00:00:00:00:00/a0 Emask 0x20 (host bus error)
ata3.00: configured for UDMA/100
ata3: EH complete
into syslog, so I removed it.
I tried a Samsung SH-S183: that was fine for most things, but I DVD-RAMs
showed up as read-only, and I couldn't find a solution.
Now I'm trying a LiteOn LH-20A1S: it writes DVD-RAMs sometimes, but
often gives permission errors that I'm still working on.
I've Googled around, and not found anything helpful with all of this.
I'm running Debian testing with a 2.6.21-2-amd64 kernel.
Yours unhelpfully
