Hi
I have used the JVC for about half a year under Mindblow 59 two or three
years ago.
I am sorry, but I have to say, that it was the worst SCSI device I ever
met:
nearly 50% of the burns went wrong, with things like opening the tray
during writing,
skipping half a centimeter on the disc (I had FREE SPACE between tracks,
really), re-
setting the SCSI bus as it liked to, and so on.
I have never used under linux, but I had similar problems under
Mindblow: the device
wasn't recognized from time to time; starting the system I could see the
writer,
starting an cdr-application and it can't detect the device...
All in all I have very, very bad experiences with this writer and it is
still the
slowest one out of the 2x writers.
Greetings, Dietmar
