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 :-/ ....
