wrar@wrars-comp ~ $ ./cdmrw -d /dev/hdc -f full
not a mrw formatted disc
LBA space: DMA
wrar@wrars-comp ~ $ ./cdmrw -d /dev/hdc -p
mrw format running

wrar@wrars-comp ~ $ ./cdmrw -d /dev/hdc -p

mount: block device /dev/hdc is write-protected, mounting read-only

и виснет на минуту. Потом 
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
       or too many mounted file systems
