first, let me start off by saying that i have burned a couple CDR's
which work just fine (2 good, 1 coaster), so the basic 6200 hardware
probably works fine (unless there is separate erasing hardware than
just for writing). also, this IS a cdrw disc, and is the one which
came with my mediamaster kit.
this is a long post, because i have tried to include everything that i
know into it to try to eliminate some amount of guesswork. relavent
hardware/firmware/software/etc info is at the end. i have not tried
directcd yet, as i am using nt4.0.
my problem is that programs such as cdtools and nero give hardware
error messages when trying to erase my cdrw disc(cdtools' error was
'bad medium detected'). easy cd creator _thinks_ that it erases the
cdrw fine, but actually does not, as when i try to write something to
the disk (with ecdc), i get a 'unfixated session' error. if i try to
'fix' it, it errors out, saying that the attempt to fix the disc
failed; if i ignore it, it starts to write, then gives a couple errors
(d0100 05/c6/01 requested address out of range, t1705 trackwriter
error, invalid description for source file) [this is when writing a
single 48k file].
i have tried both quick and full erases in ecdc (the quick takes ~2:21
according to its timer, and the full starts out estimating 3:09, but
then when it gets to 1:55 only takes a few seconds and then ejects the
disc w/o error). i have tried erasing and writing multiple times (at
least once i got an underrun error, but see below as to why that did
not seem to do my hardware)
i have also tried cdtools' option to finalize a session, to see if
this would fix the 'unfixated session' problem, but it returned with
'close session failed' error.
this disc did seem to work yesterday, with erasing, etc. i was writing
stuff to it to see if my various pc's could read a cdrw or not (they
cannot, it seems, but oh well), trying various iterations of joliet or
iso9660, or closing the disc after writing the session, or dao, or...
the disc (currently) looks like a partially written cdr: approximately
2/3 of the disc (inside portion of the radius) is of a slightly darker
tint than the outside portion. 'erasing' the disc in ecdc does nothing
to change this color, which worried me. if it changed to this state
because of writing, then erasing should make it completely solid (a
coworker stated that his does not look like a partially-burned cdr,
tint-wise). this i think is odd. the disc does say 'cd-rw' on it, and
the die/substrate is a silver/gray color.
at one point, the ricoh did not 'like' the cdrw, and it just flashed
green/orange when inserted. cycling power on the pc fixed this.
is there some way that this disc was mistaken to be a cdr by my ricoh,
or could soemthing be wrong with my drive (i bought it two days ago,
so i have 8 days left to take it back), or....?
i saw on tom's ricoh page (i think) that uv light could maybe be used?
i have an eprom eraser at home - could this work (any suggestions for
time, distance from bulb, etc)?
my hardware/software/firmware specifics:
ricoh 6200s: firmware 2.03 (came that way), revision 'f', mfg'd 11/97
easy cd creator v3.01 (updated from 3.0 (055) with adaptec's standard
also tried: nero v3.0 demo and cdtools - both gave errors when trying
nt4.0 server, with service patch 3
pc : ncr s-26 server (decent sized server - 256m ram, dual ppro, mylex
dac960 scsi, etc) - this server is currently low usage, and should not
have any problem keeping up with a 300k/s burn.
the drive has its own adaptec 7880, which i updated the drivers for,
from adaptec's site (this morning). i have brought the max sync
transfer rate from 20.0 to 10.0 (as suggested on tom's troubleshooting
page), and enabled disconnects.
[i have 2 unused adaptec 2944's on the system as well, if that
