External hard drive does not show up

[cheesepietou]

Hello everybody,

I am using an asus X52JE with windows home premium *64bit. I have an external hard drive (Lacie, 1TB) that is not recognised by this computer but works perfectly on others. I have checked every other usb port, and used another usb key that my computer recognised (so my usb ports work).

The hard drive does not appear on device manager AND on devices and printers, I can not see it anywhere, but I can hear it "run". It has no on/off button.

Could someone help me?

Thank you

PS, I have already tried this :


1. Plug in and turn on the external USB hard drive
2. Right mouse click on My Computer
3. Left click on Manage
4. Left click on Device Manager
5. Expand the USB list
6. Find the USB device for your USB Hard Drive ==> where is it supposed to be, i can not see a "lacie" name
7. Right mouse click - Uninstall
8. Turn off the external USB hard drive
9. Turn on the external USB hard drive and let it find and install the driver
10 Does it work now?

check and see if the drive is in the disk management list

in "run' box type diskmgmt.msc press enter.

if you can see the drive but no drive letter for it right click on the drive and give the drive a letter.

What do you mean, "Turn on External USB Hard Drive"? Do you plug it in before boot or after boot?
