Does a SCSI device need to be powered on boot to be "seen"?

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 a device powered on post boot? OS is Win7 64 bit Pro. Thanks.

Yes it does.

Not used SCSI for quite a while but if I remember correctly normally a device will have to be powered on so the Adaptec card can see it on boot, as far as I can remember you have to reboot if you lose connection (via unplugging the cable or switching the device off) as SCSI isn't plug and play.

OK, that figures and is what I see, thanks a lot for the help!
