Re: Shut one HD of 2 off?

 

Disconnecting the pwr cable, to the hd, has the same affect

Thats what I use to do, I prefer not to open it, will try Storagealternativ

in BIOS now.

Generally, no. 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.

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.

So I did but it must be better if it can be done another way.

I'm surprised that no one else has yet taken issue with your

comments, but I'm not at all certain that what you suggest is

the case [if by "Either there's power on the drive header, or

there isn't, and if there is, the drive is spinning (or it's dead)"

I correctly understand that you're referring to power at the

4 pin Molex].

 

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.

Disagree on part of what you said, as I've been doing it this way for 3

years running. 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.

[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).
