Hi,
Thanks for the response.
Under Ubuntu (NB the drive was under /dev/sdb under Ubuntu - is this a clue?!?):-
HDIO_GET_UNMASKINTR failed: Inappropriate ioctl for device HDIO_GET_DMA failed: Inappropriate ioctl for device
Under Centos (as /dev/hda):-
Both set to 0, so I tried to set them to 1. -d1 error as inappropriate but -u was allowed to be set. It didn't make much difference to the performance, i.e. up from ~ 2.5MB/Sec to 4MB/Sec.
as a refernence, -I gives...

In my haste for help, I stupidly hit reply and changed the subject which I thought was enough for a new message, not giving much thought for the threading, etc. So apologies for the hijack, although I would think it fairly obvious that it wasn't deliberate or obvious to me... or a big deal really. My mail doesn't thread.
Some further info for those actually interested in helping, I forgot that the HD in question had an Ubuntu 8.10 install on it, so I fired that up and hdparm -t produced 56MB/Sec. So the issue is either kernel or config.
Check if ultradma and unmasq interrupts flags are set(both under ubuntu and centos):
hdparm -u -d /dev/hda _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
