thanks for the suggestions. i really appreciate them.
sloveheart, vantecs do make nice enclosures. i actually bought a vantec NST-530S2 for my iHAS-09, but no computer i tried the combination with would recognize the enclosure or drive. i installed an Optiarc AD-7240s in the vantec enclosure, and everything works just fine now. the liteon worked fine in a desktop at work. i'm baffled.
sithtracy, do you know the model of enclosure you are using with your samsung mediatek drive?
