I am trying to mount the CD on on Compaq Presario 1620 running 4.6-
STABLE (1 Aug 2002). FWIW, I do not know if this CD drive is in 
operating condition and have never used the CD drive.  

dmesg shows this:

acd0: CDROM <TOSHIBA CD-ROM XM-1602B> at ata1-master PIO4

Attempts to mount give this error:

# mount /dev/acd0a /cdrom
acd0: TEST_UNIT_READY - MEDIUM ERROR asc=0x57 ascq=0x00 error=0x00
acd0: TEST_UNIT_READY - MEDIUM ERROR asc=0x57 ascq=0x00 error=0x00
mount: /dev/acd0a: Input/output error

# mount -t cd9660 -o ro /dev/acd0c /cdrom
acd0: TEST_UNIT_READY - MEDIUM ERROR asc=0x57 ascq=0x00 error=0x00
acd0: TEST_UNIT_READY - MEDIUM ERROR asc=0x57 ascq=0x00 error=0x00
acd0: TEST_UNIT_READY - MEDIUM ERROR asc=0x57 ascq=0x00 error=0x00
cd9660: /dev/acd0c: Input/output error

If I don't have a CD in the drive, I get this error:

# mount -t cd9660 -o ro /dev/acd0c /cdrom
cd9660: /dev/acd0c: Input/output error

Is this an indication that the drive is functional

Clues?  Thank you.
