I burned some cd's tonight, but I also had a hard time with the writer
before I could effectively use it.

After typing 
  cdwrite --dummy --verbose image.iso
I decided after 5 seconds that I wanted to add a parameter --speed 2 to
the command line and pressed ^C. 

I got the prompt back, no error from cdwrite, but the writer was locked
up. I could not even open the tray anymore (exept with brute force.) 
cdwrite would only give errors and could not even determine the device
model anymore (a Philips cdd2600.)

Only after turning the computer off and on could I get it to work (and I
did not press ^C anymore :-\ )

I've sometimes cleared it by unloading and reloading the SCSI driver.

Hmmm, how do you do that? Do you mean you unload and reload it as a
module?

A question related to this: is it posible to force a driver to unload,
even if it says 'device busy'?

I have a QIC-80-WIDE tape drive, which doesn't seem to understand the
'eof' command. If i issue this command and then start a 'tar -cf ...', tar
crashes with a stack and register dump from the kernel (or whatever those
numbers are supposed to be) and the tape device stays 'busy'. If I then
try to load the floppy driver, the kernel completely crashes with an awful
lot of (register|whatever) dumps on my screen that keeps scrolling for
about ten seconds and then stops.

iff the boot drive is not on the same SCSI Bus as the CDR drive.

Thanks to all who offered help on getting my Yamaha CDR400tx (1.0d) CD
recorder working, especially to Nathan Norman who pointed me to
  http://www.shop.de/cgi-bin/winni/lsc.pl
where I discovered that cdwrite-2.0 does not support the CDR400tx but
that cdrecord-1.5 does.

There does not seem to be a Debian package for cdrecord (is someone
working on this?) so I built it from the source at
  ftp://ftp.fokus.gmd.de/pub/unix/cdrecord/cdrecord.tar.gz
and it works great!

I do seem to have a reliability issue with some fairly cheap green on
gold CDRs.  (US$4 ea @ qty 100 with a black label thermally printed on
them by a local company -- supposed to be Sony CDRs, but they were
totally blank before being printed).  The cdrom drives on a couple of
our UNIX boxes can't seem to reliably mount them if they are written
at 4X, but (so far, at least) they seem to be OK if written at 1X or
2X.  Does write speed affect the quality of the CDR?

Also, are gold on gold CDRs supposed to be better?  I found what I
think is a pretty good deal on some HP C4432A gold on gold CDRs at
CompUSA -- qty 25 for US$70 minus US$20 rebate (limit two on the
rebate).

Well, AFAIK some CDR are marked all-speed. Those are probably a better
quality and the suffer less problems if the writer speed is high and/or
the difference in speed between the device that wrote them and the device
that reads them is relatively big.

 Also, are gold on gold CDRs supposed to be better?  I found what I

Buy a brand name. I usualy buy Philips rainbow CDR's, but other named
brands like 3M are probably ok too (I don't want my email address to
suggest any prejudice ;-) .) I'm not so very sure about the quality of
noname CDR's, but then again your needs for quality may also vary.

The price is nice but not really spectacular.

i've seen it and had the same problem. i never got an explanation as
to what the nature of the problem was short of joerg schilling
suggesting i use his cdrecord instead.

my device was an HP4020i. i also know that the same error was
encountered on a Dozer95 box.

i have not been fortunate(?) enough to attempt a burn again with 
either cdwrite or cdrecord.

but i am still interested in doing so!
