I have heard people on other lists lament eSATA drives/connectors/etc. *LOUDLY*, as in wailing, moaning, rending-of-garments, gnashing-of-teeth, etc. $0.02, no more, no less, YMMV, IANAL, & all that rot. I use external USB-drives myself when I use external drives, which isn't often, I have had trouble w/ them as well, short drive-life due to running hot. Good luck :-/ .... -- William A.
