Ok let's try this again: I am trying to install a Hitachi Deskstar 250 GB ATA/IDE hard drive into a Dell Dimension 2400 computer. When I go into the Boot Device Menu and select "IDE Drive Diagnostics", it says "Drive 0 HDS722525VLAT80-PASS" then says to hit enter to reboot. I try to reboot in any of the safe mode options, and it gives me a blue screen stating that I need to make sure the hard drive is properly configured and terminated, then run CHKDSK/F to check for corruption. I also get a message that says: STOP: 0x0000007B (0xF7C7B528, 0xC0000034, 0x00000000, 0x00000000). I get this blue screen in either master jump or cable select jump. Please advise.
