Hi Richard, |
| 18 |
|

Well, in Gentoo, the results of "hdparm -t /dev/sda" were around 65 MB / |
| 20 |
second. dmesg shows the drive in UDMA/133 mode, and I didn't bother |
| 21 |
with lspci. In Windows, however, the benchmarks are quite different - |
| 22 |
around 4300-4600 KB / second. At least I know the problem is not with |
| 23 |
the drive. |
| 24 |
|
| 25 |
That must be where the problem lies, since the 65 MB / s is about what |
| 26 |
Windows was reporting before I repartitioned it and installed Gentoo - |
| 27 |
the change wasn't immediate, but it was soon after. This is one of the |
| 28 |
things I hate about Windows... |
