I have had an external HDD (200Gb D'Max8 using USB in an Icy Box) for a while now and been very impressed. One of the things that I like is the ability to switch it on when the PC is already running and everything is refreshed immediately in Windows. Likewise you can just switch it off. I thought that I'd be able to do the same with an SATA drive (300GB D'Max10 SATA in a 350StS Icy Box) connected directly to the motherboard. It would appear that the drive is only recognised if it is ON when windows boots - I seem to have misunderstood the notion of "Hot Swap". Can you shed some light on my ignorance .
