I want know if my HDD setup is correct.
I've Triton chipset and HDD is IBM 1.7Gb, this is my configuration:
Boot report:

hdparm -I /dev/hda reports:
/dev/hda:
Model=BI-MJDAA3-7100 , FwRev=0PRI7AB4, SerialNo= Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs } RawCHS=3308/16/63, TrkSize=0, SectSize=0, ECCbytes=16 BuffType=3(DualPortCache), BuffSize=96kB, MaxMultSect=16, MultSect=8 DblWordIO=no, maxPIO=2(fast), DMA=yes, maxDMA=2(fast) CurCHS=3308/16/63, CurSects=3334464, LBA=yes, LBAsects=3334464 tDMA={min:120,rec:120}, DMA modes: sword0 sword1 sword2 mword0 mword1 *mword2 IORDY=on/off, tPIO={min:200,w/IORDY:120}, PIO modes: mode3 mode4
My setup with hdparm 3.1 is:
hdparm -m 8 -a 8 -X 34 -c 1 -A 1 -d 1 -u 1 /dev/hda
/dev/hda: multcount = 8 (on) I/O support = 1 (32-bit) unmaskirq = 1 (on) using_dma = 1 (on) keepsettings = 0 (off) nowerr = 0 (off) readonly = 0 (off) readahead = 8 (on) geometry = 827/64/63, sectors = 3334464, start = 0
If I turn off using_dma, hdparm -t reports 4.55 Mb/s, when turn on reports 2.40 Mb/s, why ?
Thanks.
