- I guess I wasn't clear. I'm aware of all this. When I said I start
- up the external drive and wait "a while" before booting the IIsi, I
- meant a >>long<< while, sometimes around twenty minutes! The behavior
- is the same: the IIsi doesn't find the SCSI device while booting (the
- drive is almost certainly spun up) but immediately after booting, SCSI
- probe (or restarting, or GCC Disk Manager) finds the drive and can
- mount it.

- But my worry is that this behavior is the symptom of something else
- that is wrong. So I ask, does anyone know why this is happening, and
- anything I can do to remedy the situation?
