I am using an MSI mobo with a VIA VT686B chipset that should allow
ATA100 operation. Here is the hdparm information:
burnt:/home/mellofone# hdparm -i /dev/hda
/dev/hda:
Model=ST340823A, FwRev=3.39, SerialNo=6EF0WCTQ
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }
RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=0
BuffType=unknown, BuffSize=512kB, MaxMultSect=16, MultSect=off
CurCHS=16383/16/63, CurSects=16514064, LBA=yes, LBAsects=78165360
IORDY=on/off, tPIO={min:240,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio2 pio3 pio4
DMA modes: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5
AdvancedPM=no WriteCache=enabled
Drive Supports : Reserved : ATA-1 ATA-2 ATA-3 ATA-4 ATA-5
Which to me shows that it is using ATA100... However:
burnt:/home/mellofone# hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 64 MB in 34.05 seconds = 1.88 MB/sec
Good god! Can that be right? The drive wasn't under any heavily load,
and I ran the test 3 times.... What gives?
