Hello,

I have just enabled HPT366 in the kernel but have not touched the bios
or drive. This is what hdparm gives:

[root@buzz:~/hdparm-5.2]# ./hdparm -i /dev/hda

/dev/hda:

 Model=IBM-DTLA-307045, FwRev=TX6OA5AA, SerialNo=YZDYZNM1366
 Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs }
 RawCHS=16383/16/63, TrkSize=0, SectSize=0, ECCbytes=40
 BuffType=DualPortCache, BuffSize=1916kB, MaxMultSect=16, MultSect=16
 CurCHS=65535/1/63, CurSects=4128705, LBA=yes, LBAsects=90069840
 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
 UDMA modes: udma0 udma1 udma2 *udma3 udma4 udma5
 AdvancedPM=yes: disabled (255) WriteCache=enabled
 Drive conforms to: ATA/ATAPI-5 T13 1321D revision 1:  2 3 4 5


Does this mean it's already using udma3?


Thanks!

Ian
