I have a Chaintech 7nif2 motherboard, xp2800 cpu, 2 sticks of 512 pc2700 kingston memory, wd 80gig and 20 gig hd. The problem is that I removed the 20 gig and the system would not reboot, it would just hang after the memory check. I was planning on reformating anyway so I thought this might fix the problem, however it did not, fdisk detects an error in the drive, but if I put the slave back in the fdisk detects the drive and lets me format and install to the drive. What is the problem and is there a way to fix? Any help would be apreciated.
