OK, dmesg after reboot with MO media IN the drive! :) #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: 121MB (248826 512 byte sectors: 64H 32S/T 121C) With this information, will I be able to format the disk with ufs, or is there further digging I need to do? I tried to newfs the drive again, thinking that the OS might have been fooled into thinking that it was just a normal drive: # newfs /dev/da0 newfs: /dev/da0: `0' partition is unavailable # newfs /dev/da0a newfs: /dev/da0a: Invalid argument # newfs /dev/da0c newfs: ioctl (GDINFO): Invalid argument newfs: /dev/da0c: can't read disk label; disk type must be specified # Obviously, FreeBDS didn't fall for it, andI still have not reached my goal! :( My continued thanks for your assistance, Greg.
