Beaver: I just looked at the maxtor site and the formerly-Quantum drives, the Fireball Plus AS series, are not listed being ATA133 capable, only ATA100. The only (pertinent) drives listed as ATA133 are the D740X series. Also, while the older DiamondMax drives had the yellow diamond next to their name, the D740X (though a "DiamondMax/Plus" drive) did not display the yellow diamond.
My guess is that the boxes labelled ATA133 are indeed the D740X drives. If anyone has received their drives, perhaps they can provide the model number. I'm guessing we won't be so lucky as to have them be the fluid bearing dirves (6L060L3), but rather the standard bearing (6L060J3).
Edit:
Anyone have experience returning online OD purchases to the B&M store? I'll probably chance the purchase, hoping for an ATA133. Is it a relatively easy return assuming I end up with an ATA100? Thanks.
