How to set up Start Motor on a SCSI Drive

[Budson]

Hi,

Using an Adaptec AHA-3940 UW controler with a Segate ST150176LW SCSI Drive I am having the following difficulty...

I would like to set it up so that the BIOS of the adapter sends a start motor command to spin up the drive instead of the drive spinning on startup all the time (DEFAULT). I have found a jumper on the drive that prevents the drive from spinning up. The documentation for the drive says the drive will spin up when it recieves a start motor comand from the controler. I go into the setup for the controler and enable "send start unit command". Drive never starts up.

Any suggestions?

The reason I want to do this btw, is that I do not always need this SCSI drive, I plan to enable it using the BIOS so I just as soon have it not spin when it is not being used.

Not too sure that this will do what you want anyway - best bet is to set the drive to spin down after a period of inactivity - use power saving settings in your OS.

As I understand the spin up feature you describe it should spin the drive up when the SCSI bios attempts to scan the SCSI bus for devices at boot time.

Hope this helps
