/dev/hda: Timing buffer-cache reads: 128 MB in 0.15 seconds =853.33 MB/sec Timing buffered disk reads: 64 MB in 1.42 seconds = 45.07 MB/sec
Which is okay for what I use the disk with. I remeber a while back playing with hdparm and getting the reads up around 60MB/s from memory.
I think you'll need to look in the IDE/ATAPI section of the kernel config there is options there *from memory* for use DMA by default and another option that escapes me for optimized use of DMA.

Sorry one more question to annoy everybody with, I have installed a new 80gb seagate drive and the problem is when I copy something to or from it I am getting a woeful 3 mb/sec transfer speed.
I ran hdparm -Tt /dev/hda and the result was the cache access was reporting the right speed but disk access was 3.5meg/sec (pathetic)
I ran hdparm again and turned all the go faster bits on, this increased it to 5.5 meg/sec.
Although I did notice that I get a DMA error in hdparm when trying to turn DMA on.
Any ideas anyone, thanks?
