Time to get a new(er) disk for linux then.
There's no excuse for a Seagate 340G PATA HD to be less than 15% of the speed of a SATA HD. It should be good for between 70% and 100% of SATA speed, depending on the actual speed of the SATA device compared to.
No wonder your system is in an unusable state with such a thing.
Clearly it's unusually slow, but a newer HD isn't necessarily going to help much if anything at all. His 7.75 MB/sec throughput makes it seem like it's been clamped down to PIO speed rather than the reported UDMA5 the device is supposed to support, worse than as if sitting on a USB2 port. It's probably time to run Seatools on the device to see if it's failing in the area where 12.1 is installed. If it's using an old 40 wire cable, first it needs to be replaced by an 80 wire, then run hdparm again.
Gunnar, give us the output of lspci please if it's already using an 80 wire cable.
Ah, now I raised this issue many months ago. At that time the kernel in openSUSE was not recognising that I was using 80-wire cables (and had been for years) and configured both HDDs to be on 40-wire cables. I had to add to the menu.lst "libata.force=1:80c, 2:80c" [no quotes of course] - and then running "sudo update-grub" - for all devices on channels 1 and 2 to be configured as being on 80-wire cables. Do a search in /var/log/messages for the word "configured" and see what ata1.00, say, is configured for re UDMA. (Or search for "40-wire".) If it UDMA33 then this is were the problem lies.
