Tried the Windows 7 boot disk, nothing, not detecting the hard drive. Tried the Seagate firmware update, nothing, not detecting a hard drive. The computer comes on, but when it does the diagnostic, there is no hard drive recognized. Do I need a new hard drive, or could it be another problem and how do I find out? If it is a hard drive issue, how can I get my files from the old hard drive? THANKS!
Is it recognized in the bios? When you picked the port on the MB to attach the comm cable, did the BIOS indicate the correct port? Was the HDD originally on a IDE, ACHI or SATA connection? Power cable attached?
Try a different port. Try a different comm cable. Set the BIOS to match what the HDD was originally hooked up as. Try a different power cable.
