SOURCE: How to format the LaCie 500GB d2 Quadra for Windows XP??

This way it should work...
Connect your drive to the computer...
Go to: Start > Control Panel > Administrative Tools > Computer management.
A new window will appear...
Select Storage > Disk management on the left of the window.
Now you will see the different drives that are connected or part of your system.
One of the drives listed there is your LaCie, i think you'll recognize it by name...
Right-click on it, and select 'format'
In the new window, select the new volume label (as you like it), the file system (use NTFS), and set allocation unit size to default.
Make sure 'Perform a quick format' is not checked...

Then click OK. Your drive will be formatted now... Don't interrupt the process

My Disk has been formated.Not recognized by Windows.How can,I reset the USB.

SOURCE: Will reinstalling Netowrk Drive (E.B.Disk) delete everything on

Wait.. If you have this hard drive it should be connected using network adapter right? you make it sound like it is connected through USB. Reinstalling the driver on your pc is not a bad idea and it will remove the hard drive files. I suggest go to another pc and search from there. Also, find out the network ip address of that hard drive. If it is plugged in to the network switch then it would be easy for you to access the files even without installing the drivers.
accessing the drives and shared folder:
start-> run and type in \\harddriveIP\sharedfolder

if you don't know the ip use the software lookatlan to search for it.
