So I have this SSD with Win XP Pro installed. If it's installed inside a laptop, connected to the onboard SATA power / data connector, it boots just fine... everything is peachy. If I take it out and try to boot the same disk over powered eSATA, it blue screens after hanging on "mup.sys" for a few seconds. I've seen a bunch of stuff about AHCI vs ATA settings in the BIOS and how that affects SATA operation with Win XP... but my assumption (I know, I know) was that eSATA vs. SATA would be transparent to the OS.

If anyone can educate me on why this is an issue it would be greatly appreciated!

the eSATA is probably on a different controller and that's why you are getting the blue screen.
