optical drives with freebsd 6.3

[gahn]

Hello, all

I am having problems to mount my dvdrom drives on dell precision 490. in the file /etc/fstab, i removed option "noauto" from the line:

/dev/acd0        /cdrom     cd9660 ro,noauto      0       0
/dev/acd1        /cdrom1    cd9660 ro,noauto      0       0

after i rebooted the machine and i am still not able to see the contents of cdroms with cmd "ls -al /cdrom".

so i did:

#mount -a
mount_cd9660: /dev/acd0: Invalid argument
mount_cd9660: /dev/acd0: Input/output error
#

on the root console, i saw console error message:

#g_vfs_done():acd1[READ(offset=32768, lenth=2048)]error = 5

i have nothing in /cdrom1.

any ideas?

thanks.
