Physical switch to disable a hard drive

Which leads would need to be physically opened to take an ide drive out of service?

I tried power, only, but that results in a parasitic flow on data lead(s).

Thanks,

Also disconnect the IDE cable. No cables connected=completely out of service.

Thanks, Aaron.

What I'm trying to do is use a physical switch, such as a toggle
switch, to incapacitate an ide drive, so it can be temporarily
isolated from the system without pulling cable or power lead. Just
don't know which conductors need whacking. Power alone will not do it,
so I'd like to know the minimum requirement to assure isolation.

I used a removable hard disk enclosure to accomplish the same purpose.
The enclosure for removable hard disk has a lock-and-key that I can
turn on/off the power of the removable hard disk. I use the removable
hard disk to protect the full hard disk backup that I made using
Drive-Image. In theory, I can buy another hard disk as a second
removable hard disk. Then, I can keep two backups.

The downsides a
- The enclosure costs money.
- The fan in the enclosure is quite noisy. Luckily, I don't do
backup that often (may be I should do this more often).

Thanks, Jay.

Very similar, but I'd rather have drive remain in its cubby, switch it
in, boot with special volumes config, run backup, switch it out, and
boot with normal volumes config.

That's the same as is currently done, except for the disabling switch
part.

There's also some concern about signal quality, with one or more of
the leads considerably longer than the ribbon cable, because of the
detour through the switching device.

Honestly, I don't really know what you are trying to accomplish. After
saying this, if you want the hard disk to be completely isolated from
anything else. You can use the removable hard disk enclosure that I
mentioned in my previous message. You can use the key to turn off the
power of the removable hard disk. If you want it to be completely
disconnected from anything else in the system, you can remove the hard
disk physically. Then, the hard disk will not even have a IDE
connection to the rest of your system. Pull it out slightly will also
disconnect it from the IDE connection without completely removing the
hard disk.

Hope you will find the info that you are looking for.
