Xp Is Gone!

have you checked ur bios settings ? or configured the jumpers correctly?

2 Hard drive types
Wester Digital
MaXtor

Board is jumperless and bios is at factory settings

Clear your CMOS and try it again. I've been having the same thing with XP lately. It looks very much like there are no hard drives but clearing cmos returns them. XP is unrecoverable though. It doesn't happen with win2k yet so I'm guessing it's some new trick from MS or .... ???

CMOS now cleared... Xp setup can not access hard drive...

Are you able to install DOS? As a test only.
Maybe you need to use a win98 startup disk and fdisk and format before trying again.
If your hard drives were not being detected, escd or cmos would give you an error right away and show no drives before it even got to the XP setup part.

BIOS sees the HDD. I click f3 to detect the HDD and it shows up. As for format it says "Invalid Hard disk, Can not open specified hard disk"
