If it does not spin up- hit it on the side.. (You can have a BIG drive or a 3.5 in drive..) C1247/C2247 or something like that. Fotnote on the SC40. The "other" SCSI connectors can use 512b sector disks, the microcode on the chanels will flip things. But it can't boot from them.. Ahhhh. That makes sense. Someone else to explain what it takes for Unix or any other OS to read something other than 512Byte sectors. The SCSI protocol don't care, so maybe a program reading a block at the time and write it to 512b blocks and pad the last one? I just need to get a clean image ASAP in the event the drives fail. I belive I could mount the file-system and make a T10 backup tape from T10. Let me knew if I can be of any help, and don't loose the bits.. -P -- Cory Smelosky http://gewt.net Personal stuff http://gimme-sympathy.org Projects
