Windows 7: Does SCSI need a device to be powered on boot to see it?

Does SCSI need a device to be powered on boot to see it?

I use an external Tandberg LTO4 tape drive for backups, but unless it's powered on at boot the PC will not "see" it. I guess I am asking if SCSI is "plug and play"? The problem is the tape drive has a noisy fan and consumes quite a few Watts, and i already have had to re-cap the SMPS inside it because it probably spent years idle, but powered up when relatively new. Is there a way of forcing the internal Adaptec SCSI card to look for an added device post boot? Thanks.

Hello Basil

To answer your first question, a SCSI miniport can be Plug and Play compatible.
If it did support Plug and Play, then it would show up in the Windows registry, here.

Often the bios needs to see it to set irq etc before windows can find it
