Hi Chaps, Who'd have thought that 7-pass formatting was what was needed? Clearly Kenneth has the (P)ATA version of the HD and not the SATA version (there's two links on the page he referred to). I suspect that the advance in 'plug and play' to which he refers is 'cable select'. I'd be interested to see what the difference in performance is between the ATA5 and ATA6 busses on the MDD. Perhaps Kenneth could benchmark (http://www.xbench.com) some drive tests before/after moving the drive? BTW, My QS2002/800 (sn#SG227B1BM1X) supports two 400GB drives on the ATA5 bus, and I believe all subsequent Power Macs will have 'large drive capability' (>128GB).
