powering off drive as system is running

[onetitfemme]

Hi *,

Say you give an option to the boot loader to only continue powering on
this and that drive. Is it possible with internal IDE and/or SATA
drives?

this of course you could do with a USB/Firewire drive, but how could
you do it with a regular one. I mean is there a "power off drive X"
instruction?

thanks

No. "sleep mode" is as good as you can get. Power consumption is brought
down to close to zero, but the drive can still be woken by software.

I assume you want some drives to be unaccessable after booting?
If so you might be able to do something with IDE passwords.
If only the bootloader knows them, it could leave some
drives locked.

OK.

1._ as you say "sleep mode" is as good as you can get, but is there a
way to:
1.1_ set it in "sleep mode" and
1.2_ lock it out of the OS via the bootloader, so that software
applications can not detect/use it at all?

otf: Exactly

... IDE passwords.

otf: Hmm! I hadn't thought of that

If only the bootloader knows them . . .

otf: Yeah, boot loaders look like the way to go. I specially like GRUB


Thanks

Me too. I don't think it has IDE passwords, but it may be possible to
hack it.

Thanks

No problem.
