I am running 5.1-RELEASE on a DELL GX150 with 512MB RAM on which I installed a new WD-1600JB IDE along
with the promise UDMA100 controller which came along with the drive. The drive can be accessed
but the access speed is very slow and I noticed that dmesg shows the following
ad4: UDMA ICRC error cmd=read fsbn 0 of 0-3 retrying
This repeats and is followed by
ad4: UDMA ICRC error cmd=read fsbn 0 of 0-3 falling back to PIO mode
I have changed the PCI slot on which the card is seated, changed cables and even hooked
the drive directly to the mother board but the problem persists.
The disc+controller however works ok on a wintel machine. Could it be some type of hard disc error ?
Can anyone help,
Thanks,
Rajarajan
