libata is not specific to Serial ATA. It works for Parallel ATA (a.k.a.

Someone will fix somewhere in the future.
The problem is here since months now and has not been fixed in Gutsy either.
I'm actually thinking to move to another distro just for this. Not the bug, the
carelessness.

I think that was a tongue in cheek answer, it should mean that the fix
would be in one of the upcoming kernel changes. Anyway here's my output

So there seems to be also a dma issue with the 2.6.20-15 .
Some more notes :-
I removed the first HDD power link momentarily & made sure that its
written as uninstalled the first HDD.& then booted from the CD. So this
time it takes the 80 GB hdd as sda
sudo fdisk -l /dev/sda
Disk /dev/sda: 8
sudo hdparm -tT /dev/sdb
/dev/sdb:
Timing cached reads: 616 MB in 2.01 seconds = 307.18 MB/sec
Timing buffered disk reads: 46 MB in 3.08 seconds = 14.94 MB/sec
This is after doing it on the disk device rather than on the partition
device. Not much of a difference.

One question: why are you using hdparm on the partition device (sdb1) and not
on the disk device (sdb)?
I'm not sure it's the same.
In any case, with hdparm -i /dev/sdb can you see whether the UDMA is being used?

nope, u mis-understood me, the issue is also with me :-

as you can see I am stuck at udma2 & cannot go upto udma5 hence even
