You can't do this the way you seem to be describing, though it depends on what exactly you mean by "shut off". Few, if any, power supplies allow selective activation of power connectors, so anything that is connected to a running power supply WILL be powered. I know of no drives that have internal switching to disconnect from live power - and if they did, how would you turn it back on?. Either there's power on the drive header, or there isn't, and if there is, the drive is spinning (or it's dead). Some drives are built to allow for hot-swapping without damage, but that's an entirely different thing. You can attach the drive to an *external* case, which has a switch. That is probably the fastest and easiest way to do this. There are USB2, FireWire, and eSata equipped cases. Note that while FireWire is supposed to support hot-plugging, in reality, it's an easy way to destroy the interface chip. Power all FireWire devices down before connecting them - shut the drive and the PC off, connect the drive, turn the drive on, turn the PC on. HTH -pk

Not sure exactly what you mean but you should be able to inactivate the (non-boot) drive in the BIOS. Right now it's probably set to autodetect on both drives. You should be able to change that to "None" or "Not present" for the second drive.

Then you cannot turn it off from the BIOS. Get off your arse and open the case. -- How to Post a newsgroup question effectively: http://support.microsoft.com/kb/q555375

To my knowledge, the "Turn off hard-disks:" method listed under the Power Schemes tab allows a signal to be sent not to the power supply to cut power to the hard drive, but to the controller to "spin it down" via interrupting 12 V to the disk drive motor. This can be clearly demonstrated by observing that a case fan pigtailed to the 4 wire hard drive power (not a motherboard) connector will continue to rotate despite the hard drive being in an "off" state. A VOM can also be trotted out to verify that each energized (both the 12 vdc & 5 vdc) conductor and ground wire remain in their assigned states during this non-rotational mode of operation. And although I don't advocate its usage (particularly given that it isn't even supportted by a Windows 98 OS), this utility would seem to indicate that what the OP wants to do could be done via software: http://revosleep.realspooky.de/

If the drive is correctly connected and the BIOS correctly configured, this indicates the drive has failed -- leaving your choices: 1. Leave the dead drive in place in the PC. It uses little or no power and has no function you can use. 2. Remove the drive. "Shutting it off" is not an option. Your PC has no "open/shut" function that concerns hard drives: drives are either operable or not, and correctly connected or not. Beware multiposting. -- Don Phillipson Carlsbad Springs (Ottawa, Canada)

The ide hard drive is connected within the firewire enclosure always, and connected interally with its data and power cables. The external enclosure is connected to the PC's onboard firewire port via firewire cable, always. I turn on the PC and allow the OS to fully finish booting. Then, I turn on the external enclosure. I use the icon in the system tray to discontinue use of the drive. Physically turning off is the reverse procedure. I use an under-monitor AC control station to turn on/off many externals including the firewire enclosure. I added a 2nd firewire enclosure about a year ago, and operate it the same way. -- Dave

[rest of useful stuff snipped] I wonder - it wasn't clear - whether the OP actually wants to be able to power off the drive in question, or just make it not appear (whether it's actually spinning or not). -- J.
