Hi Richard, Well, in Gentoo, the results of "hdparm -t /dev/sda" were around 65 MB / second. dmesg shows the drive in UDMA/133 mode, and I didn't bother with lspci. In Windows, however, the benchmarks are quite different - around 4300-4600 KB / second. At least I know the problem is not with the drive. That must be where the problem lies, since the 65 MB / s is about what Windows was reporting before I repartitioned it and installed Gentoo - the change wasn't immediate, but it was soon after. This is one of the things I hate about Windows...
