(its a st277n) there is what looks like a battery on the drive. what happens if i remove it? i want to know how i can tell the drive to low level format itself, check for bad blocks and store them in the memory. if i just remove the batery, i supose the memory would go, and the drive would have to do a media analysys and remark the bad tracks. either that or quit working forever. (or maybe until i send it the right command) (i have the software to send arbitrary commands down the scsi) i have a future domain tmc880 controller. any help would be appreciated. gwoho liu.
