I have just bought a second hand external hard drive and connected it to my PC via a usb socket.

My PC does not recognize it.

It does not show in Device Manager.

It is a Hitachi Deskstar,250GB capacity,Model No. HDT725025VLAT80.

My PC specs :

AMD Athlon X2 250 3 Ghz


NVidia GTS250 1GB


Do I need to download a driver to make the external hard drive work?
If so,I seem to have only found one site and that seems to want me to install some Norton programme that I don't want.

Thanks in advance,(I will be out for several hours after initial posting.)

It sounds like an external enclosure is being used that does not match the Hitachi drive.

Was it originally purchased as a complete package from the manufacturer or did the original owner buy the enclosure and the drive separately?

Are you sure that it worked for the original owner or did they have trouble with it too?

The reason I ask is that some harddrives require more power than the third party enclosures provide them. In that case the options are to try a new enclosure or verify that the enclosure is providing enough power to the drive or remove the drive from the enclosure altogether and install it internally into your computer.

Hope this helps
