Greg, thank you for the explanations. Below is the partition info you requested: #disklabel -r /dev/da0 [snip] 3 partitions: # size offset fstype [fsize bsize bps/cpg] a: 247808 0 4.2BSD 0 0 0 # (Cyl. 0 - 120) c: 247808 0 unused 0 0 # (Cyl. 0 - 120) # (one short question: why does it say 3 partitions and list only 2? I know c is supposed to represent the whole disk, and a is the first partion, so what am I missing?) #dmesg [snip] da0 at ahc0 bus 0 target 0 lun 0 da0: <RICOH RO-3012E 8.00> Removable Optical SCSI-2 device da0: 5.000MB/s transfers (5.000MHz, offset 15) da0: Attempt to query device size failed: NOT READY, Medium not present Ahh, I see there is an offset of 15, where would that be placed in the disklabel or in disktab? I hope this helps. Thank you agian.

What does dmesg say?
