It's alive!

After research on the net, I found many utilities that can read/write MBR: some can save it to a file and then restore from the file, some just zero-out the MBR, and other you can edit it to what ever you like(very risky...).

However, none worked for me. Some works only in Win32, and when I boot use PartitionMagic, it's pure DOS... And CHKDSK won't work off the CD... And although the WD/Zap worked by zero-out the MBR, when I boot from the Windows install CD, it still can't detect the HD. Hell, I even tried install Redhat on the HD... installed successfully, but when I booted from the Win2K CD - still can't detect the HD...

Arrrg... As a last attemp:
copied my backup Ghost image to the laptop;
installed Ghost onto the laptop;
connected HD via USB;
then restored Ghost image to the HD(via USB)

And booted... boom... it's there... That's it for me... not more stuffing around... I put on the covers for the case, and it's quite noisy... worse than I'd expected... and a lil worse off than my old Sonata... So much for the downgrade...

Another thing really bugs me... it always says ..."detected new hardware: nVidia PATA RAID device...", but when comes to install driver, it will always have error, even with the latest driver downloaded form nVidia. Hmmm... to fix or not to fix...
