Try the HDTune benchmark and report back. If you see
a "curve" for a result, that would be normal. If you
see a "flat line" then something is wrong. The only
time a "flat line" is acceptable, is for an SSD, USB flash,
or a software RAMDisk.

This is a RAMDisk back when I was testing it. This is a flat
line. If your rotating hard drive is in PIO Mode (polled transfer),
then transfers will be limited to the 4 to 7MB/sec range and there
will be heavy CPU usage. PIO Mode is the one to avoid, for any drive.

This is a regular (rotating) hard drive. The curve has about a
2:1 ratio between the best and worst parts of the curve. If both machines
have rotating hard drives, and the transfer mode is DMA as it should be,
it will look like this. Older drives, the scale of the graph will
be reduced (60MB/sec at start down to maybe 30MB/sec near the end).
But the results should still be better than when a drive is stuck in
"flat line" PIO mode.
