This is actually (I think) the only part where I disagree with you. SATA drives (RAID or not) are supposed to be hot swappable (hotplug in some literature). As we've all pretty much agreed, since he installed Windows with them in the IDE emulation mode, he can't hot swap. XP does not naitively support the AHCI stuff, but any board built with SATA 2.0 (revision 2, not SATA II) support does - so for some people it would be possible to have a very early SATA board, and Windows 7 and not have the ability to hot swap.All this about the Esata drive not being recognized, is IMO moot. The OP states, the Esata drive is only recgonized when it's turned on >> before << boot. I'm standing firm with the opinion that that's to be expected, since if it's not turned on (at boot poll) then it technically doesn't exist. Since the system is likely not true hot swappable RAID, why would it appear after initialization. (In the case of the H55 board, the only concession that is made to XP, is that BIOS >> defaults << to IDE). Although in the next revision they might think better of that, but who knows).
