xmcd sometimes fouls up the cdrom drive
Hi,
I have a NEC 4 disk cdrom drive. Sometimes after using xmcd, the
drive seems to get all balled up. It seems to get confused about whether
there are any CD's in any of the 4 slots and just keeps cycling through them
looking. When it gets in this state, I can't play any more CD's
If I quit xmcd, remove the audio cd and replace with a iso9660 cd, I
can't mount the CD. I get the "bad super-block, device busy or wrong fs
type" message. If I switch to single user mode the error message is more
verbose when trying to mount the cdrom drive:
------------------- error from single user mode ----------------

-------------------- end single user mode error message--------------
I'm wondering if anyone knows what gives, and better yet, how I can
reset the device to regain control. I've tried "rm /dev/hdb" followed by
"mknod -m 771 /dev/hdb b 3 64" but that does't help. The only solution I've
found thus far is to reboot ( :¬( )
Any ideas welcome.
Gerald
