|I have a WD600BB-OOCAA1 and found this drive to be very good till I tried to load the new xp operating system.after it formated my hard drive the drive started a clicking sound so I turned off the system and inspected for error. Could not find anything so I tried a different drive and it worked. I connect the WD600BB-O0CCA again. Now the bios does not see this drive and the drive is clicking again. What is wrong? How can I fix it?
