SATA CDROM/DVD fails to mount CDROM
Mounting CDROMS on a cdrom/dvd/-rw used to work. At first I had a plextor 712s and thought it had
failed. I replaced it with an Optotrac and now a LITE-ON DVDRW LH-20A1L. (These are all SATA drives)
Wonder what I need to back out of lenny to get it to work again?
mount cdrom0
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
missing codepage or helper program, or other error
sys log says: kernel: ISOFS: Unable to identify CD-ROM format.
