Yeah, that qualifies as a problem all right.

It doesn't.

If 2 different CD-burning programs on 2 different OSes are failing in
similar ways, I'd suspect hardware problems. When cdrecord coughs up an
error, what is the exact text of that error? Don't use XCDRoast to try
and find this out; use cdrecord directly--XCDRoast is the *worst*
frontend for cdrecord available and I don't know why anyone still uses
it.

"Coasterizing?" Verbing weirds language.

Don't paraphrase error messages; report the exact text! Go read

Sounds like a hardware problem to me. Look through the output of dmesg
for any strange SCSI errors relating to your CD-RW, and you'll probably
see all kinds of information.

When it comes to hardware, you get what you pay for. If this was a
cheap drive, it has cheap parts in it, and it'll have a higher chance of
failure. I've owned several CD-RWs, and the only ones that have lasted
past their warranty periods without spectacular hardware failures have
been the Plextor 12/10/24 in my desktop and the Sony CRX 700E in my
laptop. Buy quality parts (for CD-RWs, this means "Plextor") and you
will have fewer problems in the long run--but it's your call as to
whether hours of time diagnosing/fixing problems is worth the extra $50.
