Hot-swapping IDE drives
Don't ! IDE doesn't handle hot swapping at all. Sure, it may work for you, if your IDE driver is compiled as a module (only possible in the 2.2 series of the kernel), and you re-load it after you've replaced the drive. But you may just as well end up with a fried IDE controller, and you'll be looking at a lot more down-time than just the time it would have taken to replace the drive on a downed system.
The main problem, except for the electrical issues that can destroy your hardware, is that the IDE bus must be re-scanned after disks are swapped. The current IDE driver can't do that. If the new disk is 100% identical to the old one (wrt. geometry etc.), it may work even without re-scanning the bus, but really, you're walking the bleeding edge here.
