OK. I'll bite - I have my /dev/hda and /dev/hdb set with 32-bit on
and dma on.
I do an 'hdparm -i /dev/hdb' and see that my drive (IBM deskstar
30 gig) is capable of udma5, but there's an asterisk in front.
[root@m206-157 root]# hdparm -i /dev/hdb
/dev/hdb:
Model=IBM-DTLA-307030, FwRev=TX4OA50C, SerialNo=YKDYKTJ8513
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=16383/16/63, CurSects=-66060037, LBA=yes, LBAsects=60036480
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=yes: disabled (255)
Drive Supports : ATA/ATAPI-5 T13 1321D revision 1 : ATA-2 ATA-3 ATA-4 ATA-5
And what (if relevant) is the difference between udma and mdma? I should
add that I have not put this drive on ATA-100 because of reported issues
with that interface - this may also be a non-issue right now, but I
don't think it was ca March of 2001, and I already have an older
drive (Maxtor) on /dev/hda. So, I didn't want to hose things *too*
much.
Needless to say, I suppose I can try "better" modes (does hdparm
display which? it seems just to say that I'm using DMA, but doesn't
mention which).
