[techtalk] Using CD-Rom drives with linux.

[Tania M. Morell]

Conor, 

Thanks.   but I don't have an /etc/cdrecord.conf

[root at caladan /root]# cat /etc/cdrecord.conf
cat: /etc/cdrecord.conf: No such file or directory
[root at caladan /root]#       

How is this file generated?  should I just create it manually? Is this a
file cdrecord looks for when it runs?

I was able to copy an image of a music cd from CDR in raw, cdr, and wav
formats. (I think cdr and raw and the same thing, though)

I ran a couple tests before attempting to copy the images onto a
recordable cd.

With audio cd:
[root at caladan /var]# dd if=/dev/cdrom2 of=/dev/null
dd: /dev/cdrom2: Input/output error
0+0 records in
0+0 records out
[root at caladan /var]# 

With data cd:
[root at caladan /var]# dd if=/dev/cdrom2 of=/dev/null
1328864+0 records in
1328864+0 records out
[root at caladan /var]#    

After doing a few tests..  something happened which locked the drive and
it could no longer be openned and it wouldn't respond.  

DUMMY (BUT SUCCESSFUL?) TEST:

Any ideas how to 'unlock' or 'reset' the drive without having to reboot?
