Hi *
I have some preoblems with my new CD-R (it never works and I donīt
have Win9$ to check out if this a Linux-Problem or a
SCSI/hardware-failure).
I use cdrecord to roast CDs (I tried to use it).
Some facts about my machine:
CPU: K6-2 300
RAM: 96 MB
SCSI: (Read the attached files scsi_*.txt.gz)
Adaptec 2940AU <==>ZIP100(int)<==>TEAC CD-R<==>Pioneer
32x<==>Micropolis9.1
Controller and HDD terminated.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
What I tried: I tried to burn an image, I built with xcdroast -->
Master (but I think that makes no sense). After some output (see
attached cdrecord-error.txt.gz) I get this error:
[...]
Waiting for reader process to fill input-buffer ... input-buffer
ready.
Judging disk...done.
Calibrating laser...done.
cdrecord: Cannot allocate memory. Cannot send SCSI cmd via ioctl
^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^
[1] [2]
[1] cdrecord reserved the default amount of memory while in progress,
I watched to a "top" while loading it.
[2] Is this just an error becausee of [1] or do I have a problem with
my SCSI-System? I think not that thereīs a general SCSI-problem
because copiing a large file (>600M) from disk to /dev/null brings me
7.5 MB/s thats a lot for my old Micropolis I think.
Another thing: This CD-R is able to read CDīs with 8.1x speed
(tested by "time cp /dev/scd1 /dev/null" on a very scratched ~610MB
CD-R)
Laser should be ok, SCSI-Interface too
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
My Kernel Setup is like that:
<*> SCSI disk support
< > SCSI tape support
<*> SCSI CD-ROM support
[ ] Enable vendor-specific extensions (for SCSI CDROM)
<*> SCSI generic support
--- Some SCSI devices (e.g. CD jukebox) support multiple LUNs
[ ] Probe all LUNs on each SCSI device
[*] Verbose SCSI error reporting (kernel size +=12K)
[ ] SCSI logging facility
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I hope not to have a buggy CD-R.
Greetings
