LaCie 500GB external HDD stoped working ?

Try connecting the LaCie to another computer. If this still does not work then the LaCie is faulty.

Check your BIOS > StartUp sequence
Maybe the USB boot option has much higher priority that HDD boot. Try exchanging their priority and then reboot, with your external HD connected to pc.

The problem that has been inherent with all LaCie external harddrives, is the interface in the case itself.

Interface:
All external harddrives have a Style of harddrive that is used in a laptop, or one that is used in a desktop computer.
Laptop harddrives are 2-1/2 inches across in width.
Desktops are 3-1/2 inches across.
Your LaCie will have a 3.5, (3-1/2) inch desktop style harddrive, inside the case.

There are two main Types of harddrives.
IDE and SATA. (There is also a newcomer. SSD. SSD isn't being used in LaCie external harddrives at the moment, to my knowledge)

Your LaCie will use a SATA harddrive inside it.
This is an example of an average SATA harddrive,

The photo of this harddrive is tilted at an angle, that doesn't readily show the interface connection, but it helps to explain.

At the bottom of this harddrive in the photo, and to the left, is the interface area.

Viewing the harddrive, look at the four metal pins on the extreme right of the harddrive. To the left of these pins is the Jumper pin area. (Has a white jumper on two of those pins)

To the left of the Jumper area is an opening, and to the left of that, is a long slot. The first small slot area is for the 7-pin Interface cable.
(Data cable) The next slot to the left, is for the 15-pin power cable.

This 7-pin Interface mates up to socket holes in a connector, of the case of the LaCie external harddrive.

It is this interface connector, inside the LaCie external harddrive case, that is the problem.
Solution?
Buy a quality, in-expensive External Enclosure, take the harddrive out of the LaCie, and install it in this enclosure.

Examples of 3.5 Sata External Enclosures,

(From $15 to $35, is a good range for a decent external enclosure)

try it on different usb ports on your system
try replacing the cable which connects the hard drive with the usb port
if this does not works the problem lies in the portable hard drive and i think it would be under warranty period so get it checked

perhaps this? http://www.lacie.com/us/support/support_manifest.htm?id=10253&guideid=10167

You're not missing any step at all, because with SATA hard drive if its really working your computer should
automatically detect it and since this hard drive suddenly stop working there's a possibility that its already
fried but if you want you can try this hard drive again to a different computer and if still not detected by
second computer its already dead.........

Just buy new external ( HDD ini is fine) just change the external for both off you

Try to put hdd in ( for whillem 74) another EXTERNAL!Or just buy new external then put hdd in new external.There is no way to repair it i think!!!

For Fiddler 51 Try hdd in external if it wont acept also then hdd is damanged!

If you open that drive, you will destroy it. Those drive are airsealed, and are manufactered in a sterile environment. You will need to seek out professional recovery.
