The problem is that I really need an eSATA port to connect my external mirrored hard drive box to and the eSATA card that I bought -- apparently all of them, actually -- is incompatible with the Promise Technology RAID support on the motherboard. But I went online and just found a card with one eSATA and three internal SATA ports and RAID support. So I've ordered that card from one supplier and two new 400 GB SATA drives from Fry's (with a five year warranty). Total cost with expedited shipping is less than $400, which seems pretty cheap right now, given that the computer that I'm mixing on could start kicking its little legs in the air at any moment.
This does mean that I won't be uploading MP3s for catalana to listen to tonight (or when she gets back from Germany). *sigh*
