this harddrive I replaced a few weeks ago. It is a Toshiba 60GB ZIP harddrive ! It worked fine, I had videos and music. Now I just replaced the LCD, casings & battery (LOOKS BRAND NEW!!) and I get the sad HHD face!! What’s going on??!
It sounds like the hard drive cable is loose. Check the cable and see if that’s the case, otherwise the cable is damaged.
