Filesystem panic (dev 08:01).
File system has been set read-only
Directory 494: bad FAT
There also many error entries like this:
SCSI cdrom error : host 1 channel 0 id 0 lun 0 return code = 28000000
ILI Current sd0b:00: sense key Illegal Request
Additional sense indicates Illegal mode for this track
I/O error: dev 0b:00, sector 68
do you think I should try and reformat the USB drive?
