>From what I can ascertain the "SONY DVD DW-D26A" is not a SONY drive. It
>appears to be a re-badged Lite-On SOHW-1673S. See here for more details:

One previous person also reported this problem with a Lite-On drive but no
model ID was supplied (see Bogolisk 2007-07-24 above). The diagnostic error
message reported is consistent with this bug:
hdd: DMA timeout retry
hdd: timeout waiting for DMA
hdd: status timeout: status=0xd0 { Busy }
ide: failed opcode was: unknown
hdd: drive not ready for command
So, yes, it does seem that there may be some Lite-On drives experiencing this
problem. A comparison of kernel logs for the bug between Lite-On & TSSTcorp
would be interesting. This Lite-On drive appears to have caused problems for
both Linux & MSWindows systems. A quick web search shows that numerous
MSWindows users have had trouble with the Lite-On SOHW-1673S (very high failure
rate when burning DVDs). Firmware upgrade is widely reported as the solution
for MSWindows users. Firmwares JYS2 & possibly a JYS3 are available (see here:
http://forum.rpc1.org/dl_firmware.php?download_id=2081
Some other drives that may have trouble (very few reports)
TSSTcorp CD/DVDW SH-S183L [bug with SB01 : SB02 (28/6/07) is available from
Samsung]
TSSTcorp CD/DVDW SN-S082D [SS03 (4/3/07) firmware upgrade fixed bug -
note:there are two (csel=high or low) firmwares for this drive]
TSSTcorp CD/DVDW TS-H552B [TS12 seems to be latest in long line of firmware
upgrades]
However, almost all reported drives exhibiting this problem are
TSSTcorpCD/DVD TS-L632D optical drives.
Also note that this bug commentary is not the only report of this or
similar bugs with the TSSTcorpCD/DVD TS-L632D.
Bug #75295 mostly reports on the bug concerning IDE connections
Bug #84603 mostly concerns PCs with SATA connections
Bug #117441 concerns System76 PCs.
Nearly all reported optical drive models in the above three listed bugs
(and their included duplicate bugs) are TSSTcorpCD/DVD TS-L632D.
Furthermore, all those with TS-L632D who have done a firmware upgrade to
SC03 or SC04 have reported that it fixed the bug.
