rikapple,more info required. Is this the only HHD in the computer?what were you doing when you lost the use of it?when you say the bios can see it what exactly does it say in refference to it? In the device manager are there any yellow question marks or exclamation points beside it? When you do a diagnostic from the device manager what is the result?What is your operating system? Have you added any new hardware around the time this "loss" occured? truenorth

No this is the second hard drive I have tried using it by itself but windows will not detect it. I am using Win XP sp2.
THe bios detects it as the 120 hd it is. Either in slave or master.

If i run i diagnostic it says that it is working correctly

only yellow exclamation marks are for a raid controler which i dont have!

Drive model number? Check if it's ATA or UATA and that the correct ribbon cable is being used.

Were the files on this disk created on your pc, was the hdd ever recognised and operable on your pc?
