I embarrassed to admit that this does seem to be the issue. A while back, I checked the drive settings, but I must have confused -i & -I. The drive (-I) was reporting that it was set to UDMA7, but the (-i) option reported that no transfer mode was set. I'm guessing that this is related to the fact that these drives are SATA. Any thoughts about UDMA7 vs. MDMA2? The seem to return similar performance characteristics, so I'm not sure what the decision point would be. > As an afterthought, it may also be worth while running dmesg, and > looking at the output, check to make sure all chipsets are supported, > see if there are any error messages being thrown up. > > Doug Nothing odd in dmesg. -Brian
