I have no idea if it makes any real difference, but I added 'idebus=66' to
my lilo.conf to get a 66MHz bus speed (assuming your motherboard is happy
with this).

[OT} - Odd thing here is that my work PC says 'neither IDE port enabled
(BIOS)', yet there are 2 IDE disks inside it! :-) Very odd.
Okay, but my home PC (with 2GB and 13GB Seagate disks) says:
ide0: BM-DMA at 0xffa0-0xffa7, BIOS settings: hda:DMA, hdb:pio
ide1: BM-DMA at 0xffa8-0xffaf, BIOS settings: hdc:DMA, hdd:DMA
Your IDE controllers are reporting pio, but I would have thought that with
your disks it should be dma. Try 'hdparm -i /dev/hda' and for /dev/hdc to
see what parameters the disk is saying it knows about. You can then run
'hdparm -v /dev/hda' (and for /dev/hdc) to see what ones have been set.

Wow - a 2MB cache. My Seagate 13GB disk only has a 512KB cache.

It seems that your disks are not requiring dma but using pio instead. I have
no idea why your 2GB seagate should be coming up any different than mine -
as far as I am aware there are no jumpers on the disk itself, unless
someone else has told it to change its operating parameters (the hdparm -k
option will do this). Alternatively is that the bios has been told to use
pio rather than udma. I would very much run hdparm to see what the disk is
actually saying it can do, and then (again using hdparm) set dma and
whatever else (I set multi-sectoring). Check and set your bios as well.
Using hdparm, the 2GB seagate should look like:
Model=ST32122A, FwRev=3.02, SerialNo=XKG89828
Config={ HardSect NotMFM HdSw>15uSec Fixed DTR>10Mbs RotSpdTol>.5% }
RawCHS=4092/16/63, TrkSize=0, SectSize=0, ECCbytes=4
BuffType=unknown, BuffSize=128kB, MaxMultSect=16, MultSect=16
CurCHS=4092/16/63, CurSects=-264241090, LBA=yes, LBAsects=4124736
IORDY=on/off, tPIO={min:383,w/IORDY:120}, tDMA={min:120,rec:120}
PIO modes: pio0 pio1 pio3 pio4
DMA modes: mdma0 mdma1 mdma2 udma0 udma1 *udma2
As you can see the disk itself says it can handle udma. I assume the
asterisk refers to its default mode (udma2 in my case).
Final option, as has already been suggested, is that the disk is on its way
out, but its odd that it picks on dma but allows pio to work okay. I would
have though some more drastic problem such as the disk writing to random
sectors and the like.
Let us know how it goes, and if you need any more info.
John.
