i HAVE A OLD HARD DRIVE THAT CAME OFF A DELL DESKTOP THAT I WANT TO USE IN ANOTHER TOWER BUT WHEN I INSTALL IT AND BOOT IT UP IT DOESNT WORK. i WAS THINKING THAT MAYBE I NEED THE DRIVER FOR IT SO I CAN BUT INTO THAT HARD DRIVE. BUT IF THAT IS CORRECT HOW DO I DO THAT. NEED SOME HELP OR IDEAS ON THIS HARD DRIVE.
Most important question pointed out by Skepticals -- what do you mean by "not working"?
I'll take a different approach to attempt to answer your question, since Skepticals already targeted the configuration concerns: Did you simply remove the old hard drive from the other computer, install it on the new computer, and turned the new computer on, expecting the computer to boot to the OS as usual?
