Thanks for the suggestions. I have an old Adaptec 1452CP. The driver doesn't seem to support the proc-fs: [EMAIL PROTECTED]:[/proc/scsi/aha1542]$ ls 0 [EMAIL PROTECTED]:[/proc/scsi/aha1542]$ cat 0 The driver does not yet support the proc-fs Also, by "than stuff that's running already" do you include the host adapter? If so, I'm SOL because my host is on ID 7. I've tried adding the new drive on ID 6 and mounting it, and it doesn't seem to work. It is formatted fat16 already. My only experience with this is on solaris where there was a command to poll the SCSI id's (I think solaris 2.5) that could be called by root at any time. -Dan
