From stepping through our ATA code, it seems like the card is just not responsive. For instance, on certain Promise cards you cannot do: atacontrol detach $promiseChannel atacontrol attach $promiseChannel or: atacontrol reinit $promiseChannel Which is weird, because the other 3 channels are being used at the same time without any problems. My advice: Stay away from Promise, or at least the "Promise PDC40718 SATA300 controller" but I've heard the same horror stories with numerous other chips. -- Rick C. Petty
