Please try the IDE test above! (Score 1)

Linux 2.1.132
Intel p255MMX (Yeah, it's overclocked, bus is running at 75Mhz.)
128Mb edo, bios default for 60ns in my award bios.
(simms are 4x 32Mb, 2x TI and 2x Panasonic)
Mobo: Asus T2P4 Cache: 512Kb
HDD's:
1.0 Gb samsung pio-4
2.5 Gb bigfoot pio-4
4.3 Gb bigfoot pio-4

On all the disc the outcome was the same,
I "summed" for 30 times each disc.

I also tried it on my nameserver,
Linux 2.0.36 + egcs patch
AMD 386DX40
Motherboard = unknown
8Mb "topless" (8x1Mb)
420 Mb Seagate
BIOS MEM Setting: as conservative as you can get
I tried it 20 times here, also no difference in
sum.

Weird shit happenin' in yer machine...
Try other ide cables, I had problems with that in the past, my hdd's used to spin down (a bit) click and the get up to normal speed again. Bad connectors caused the hdds to reset once in a while, this cost me some write and read errors including some badblocks! (my system tried to read/write while the heads were resetting -> the "click" sound).

Anyone here who has/had this problem too?
