My lacie hard disk 1tb all of a sudden isnt

you may need to swap the usb port it's plugged in

Be sure to install any drivers or software that may have came with the drive.

Check My Computer, to see if it detected.
Try it in another USB Port.

Hello,
for the product that you selected for your question, it is impossible for the LaCie Network Assistant to see it because it is a Local drive (USB).
The LaCie Network Assistant only detects the Network LaCie drives.
Regards,

You need updated drivers to get that working. Get OIbit Drive Booster on the internet at IObit.com

yes yust download recover my data then format disk after recovery then repartion disk

Just contact www.lacie.com great support. their answer for my drive was to upgrade the drive version and to reboot the drive. Maybe the last thing is enough. For me it worked.

If necessary update driver http://www.lacie.com/nl/support/drivers/driver.htm?id=10156

Follow the procedure below to reset the Network Space to factory defaults:

1. Move the power switch to the OFF position. Wait for the drive to shut down.
2. Turn ON the drive.
3. Within about 3 seconds, flip the switch OFF and On several times.
4. Immediately turn it ON

If the light flashes quickly, the unit is resetting itself. Attempt to connect to the drive again after about 1 minute using the default username and password (by default, they are both admin.)

The normal, slow format can take hours, you could have selected quick format if you had the option would have problably taken around 10 seconds to a minute.

Get your data off that thing right now before it dies.

Me too, i bought a LaCie BigDiskExtreme+ (1tb) and it keeps giving me Device removal error.  I'm running Mac OSX Leopard.  Worked for 5 minutes, now everytime it turn it on it goes away and comes back up, always giving me the error message.  Any advice ?

check wires connecting them together first, ok?

then, turn off the LaCie, connect to your MacPro, and then turn on the drive..

that should show as a mounted drive.

need printer drivers update?
