Most probably, following are the causes:
1.The file system is damaged and cannot be mounted.
2.You use a standard 40-wire connector cable to connect the UDMA drive to the controller instead of the required 80-wire, 40-pin cable.
3.The basic input/output system (BIOS) settings are configured to force the faster UDMA modes.
First, try this:
Go to your Bios and restore your default settings.
If it's a damaged file system case then:-
1.Insert the Windows XP CD-ROM into the CD-ROM drive, and then restart the computer.
Click to select any options that are required to start the computer from the CD-ROM drive if you are prompted.
2.When the "Welcome to Setup" screen appears, press R to start the Recovery Console.
3.If you have a dual-boot or multiple-boot computer, select the installation that you must access from the Recovery Console.
4.When you are prompted, type the Administrator password. If the administrator password is blank, just press ENTER.
5.At the command prompt, type chkdsk /r , and then press ENTER.
6.At the command prompt, type exit , and then press ENTER to restart your computer.
This should solve your problem.
