At my former place of employment, we had quite a few 1.6 WDs die. They would usually have that clicking problem. My advice: download from WD their disk diagnosis program. You put it on a DOS floppy, boot the floppy, and run the program. If the program says the drive is dead, WD will replace it. Note that WD will not replace any drive that was stolen along the supply chain - a good reason to avoid grayware drives, as someone else mentioned. Carl
