From the looks of it, warm swapping will be the route we will have to go. This system is a 2U setup that has 4 hot swappable drive bays. Oh this is so much fun :) @Fabian – ya, lazy web from this point forward :) Anyways, the reason that works is because it converts the SATA drive to a USB drive, which everyone knows that USB is easily hot swappable.

Check this dock: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=3516746&Sku=T925-1219 This reviewer used it with Ubuntu 8.04 and it works out of the box. You may also use enclosures wich will better protect the drives, and have USB, firewire, network AND eSata connectors, so you can choose whatever works faster for you. Would that be what you want ? Next time ask the lazy web BEFORE spending your time on it ;) Mhh… sorry for stating the obvious but… put them in external enclosures / docks ?

I know I have done this in the past with and without RAID, but I think that was all configured with the Compaq DL380s back then.
