cdob was right.  After remove that a few drivers, I finally can see my HDD and my computer is working now.  Thank you so much!

cdob,
Thanks for the clarification. 

To avoid conflicts, do you mean to remove the drivers you mentioned from then .ini file?  I can find mraid35x, megasr and MegaINTL, but what is KR10N?  I don't see it anywhere.

Also, I found an intel raid controller driver at
http://h10025.www1.hp.com/ewfrf/wc/soft … ct=1843644.  It is an .exe file.  I don't think I can use it.  Contacted with HP support, but they keep telling me how to do a system recovery by pressing F10.

Any idea how to find the driver?  Thanks.

Hello,
My computer (HP Desktop, Pavillion a1440n XP Media Center) was crashed due to a registry change 3 days ago.  I tried to use UBCD4Win to boot.  Unfortunately UBCD4Win didn't recognize any of my hard drive volumes.  Downloaded the latest mass storage drive pack for XP 32-bit from here,  built image and ran UBCD4win boot CD again, but I  still can't see the hard drive volumes.

The motherboard of my computer is Asus P5LP-LE.  The hard drive is Samsung SP2504 (IDE SATA-II, 3.0gbps).

I checked HP and Samsung support website for my hard drive driver, but I only saw some firmware updates or diagnosis tools.  I also looked at FAQ and some posts here, like "Where can I find drivers for my hardware?", but still have no luck. I urgently need the Samsung hard drive driver.  Your help will be appreciated!
