Boot drive problem

I have been using my RT2500 AMD system flawlessly for over 9 months now.
My problems started when I tried replacing my video drive (100GB WD) with 200 GB WD.
I was not able to run the 200 GB at UDMA
speeds. Windows XP defaulted to PIO mode.
I followed advise posted in the WD and
Microsoft sites, but that did not help. I finally resorted to leaving the 100 GB in its place.

My Problem now is the Boot drive, a 40 GB,
7200 rpm Samsung HD. its speed has dropped
tremendously recently down to 3.2 Mbytes/s.
Originally it boasted speeds in the region of 36-27 Mbtes/s (Read/write) at UDMA 5 when
tested using Matrox benchmark utility.

The A/V and boot drives share one IDE channel
with one cable. The second IDE Channle has my
pioneer A03 writer and a DVD ROM

The A/V HD shows speeds 2.5/36/45.6 Mbytes
for min, average and maximum for read/write of a 13GB file with about 60 GB of material on the drive. The drive does not pass the Matrox test because of the low (2.5) minimum speed.

How can I improve the performance of my BOOT drive? I use the drive for my Photoshop work which has been affected severely.

For info:
I have Windows XP service pack 1 installed

Your input will be highly appreciated.

is the cable a 80 wire , 40 connector cable.
usually blue connector at one end ?
if not that may be causing the problem.
is dma enabled on all drives , first in bios , and then in the device manager.

does the amd board require via chipset drivers ?

p.s. please pull the duplicate post in faq .... i thought i'd lost my marbles again when i couldn't find this reply.

UDMA 5 is set in BIOS and through
Windows device Manager.

My motherboard is ASUS A7A266 and don't
think has drivers as you may have suggested.

I do have the 80 pin IDE cable.

Last night I CHKDSKed the boot drive with
the recovery option and discovered there were some sector errors. I did not manage to resolve them all and there was no impact
on the benchmark readings.

Gary,I looked in the FAQ to remove my posting on the subject, but it was not there.

http://www.asus.com/support/download/item.aspx?ModelName=A7A266 is a bios upgrade which

Support AMD XP2100+ CPU.
Add LBA 48-bit addressing mode support.
Fix Samsung DDR problem.

maybe that is what you need .....

you will find ide drivers on the support cd that came with the motherboard

page 80 of your manual explains all.

Thank you Gary, but I already updated
my BIOS with this version, hoping to sort out an earlier problem for hard disks greater than 137 GB.

I uninstalled my hard disk and IDE channel and allowed Windows XP to reintall them after
rebooting. Doesn't that amount to the same thing ?

depends whether it reloads the wrong drivers again.
did you ask the machine to check for newer drivers on the net using windows update\hardware
many motherboard manufactureres have to tune a set of their own drivers to run with their equipment and usually state in the manual/on the supplied cd that they should be installed.

from the pdf version of your manual i downloaded yesterdayit states that drivers are included on the cd.
whether windows xp and it's update process have found newer drivers , i wouldn't know , but if you still can't get full thruput , i would suggest that there is something wrong with the drivers installed.
on the disc should be

ali agp drivers
ali ide cache and utility
c-media pci audio driver
asus pc-probe --- temp check prog etc
pc-cillin 2000
cyberlink video and audio apps
and a show motherboard information program.
