Hah!
talk about hard drive envy ;o)

root at Waza_1 ~/ # hdparm -Tt /dev/hda
Quantum Fireball 1080A
/dev/hda:
 Timing buffer-cache reads:   128 MB in  5.09 seconds =25.15 MB/sec
 Timing buffered disk reads:  64 MB in  13.81 seconds = 4.63 MB/sec

root at Waza_1 ~/ # hdparm -Tt /dev/hdb
Quantum Fireball ST3.2A
/dev/hdb:
 Timing buffer-cache reads:   128 MB in  5.03 seconds =25.45MB/sec
 Timing buffered disk reads:  64 MB in  10.91 seconds = 5.87 MB/sec

stuck using multiword DMA 2, old Triton 1 chipset (on a P-133)doesn't cope with UDMA, and will only cope with pio on IDE1 !! Argh!

Cheers
