Can I remove the disc from a LaCie 300770 250 GB drive and try it in another drive? The drive is not working, so I hope the disc is ok.

Try this...

use a long bladed kitchen knife to get carefully spread apart the sides from the bottom plate. there are 4 small tabs along each side of the case going int 4 slots on the bottom plate. The long sharp blade inserts easily between the side and bottom plate.
Carefully pry the side away from the bottom plate starting from the front working towards the back. You gently twist the blade to get the tabs out of the slots. the first one is the hardest. After that they pop out easy.
to remove the hard drive mechanism, once you have the bottom plate off, remove the four silver screws--two along each side--then use the knife to separate the sides of the hard drive from the case, so that the front of the drive is angled up (you'll also have to pull the activity LED loose from its hotmelt glue), then slide the drive out of its metal mounting bracket--you won't be able to pull the drive out along with this bracket.

500Gb Lacie D2 Quadra with the same problem of flashing led and not mounting on the desktop (Mac G4 Mirror), traced to the power supply (57w) going down on power, both 12v and 5v supplies are available but the main power to run the drive drops to below an adequate output, hence the clicking and whirring evident from the drive with simultaneous flashing led.

Testing with another Lacie power supply (250Gb D2) this time a 34w unit got the drive up and running, however, and this is the reason for this post, this lower power PSU failed a week later whilst waiting for a warranty replacement from Lacie (5 weeks and still waiting for the new PSU from them. they have no stock)

Message for all Lacie D2 users, check the power supplies first, test with another Lacie PSU, do not run the drive on a lower rating (34w) PSU it will fry it and leave you with another failed power supply.

If you are in a tight spot use the temporary power supply to move your data to another drive and get the correct 57w power supply before running the drive again.

Don't do as I did assume any Lacie power supply will run any Lacie hard drive, they won't, fortunately I had a second back up, but am 2 drives down and no new PSU's available to buy anywhere.

Try and purchase another spare 57w power supply, something all D2 users should do for long term security, as these do not seem to be very reliable and getting warranty support from Lacie on these is currently impossible.

The lack of 57w power supplies from Lacie and its distributors across the world is surely a warning to be noted!!!!!!

Buyers beware!

Go to computer Management, change the drive letter from F:\ to any letter.

Simplest solution: back up the data on the drive and repartition it (which will wipe it). Otherwise it sounds like it could be a problem with the file tree or structure of the drive, the configuration files could be corrupt, some program could have stored temporary files in a hidden place that cannot be deleted without making the program delete them, etc. If you are on a mac, spotlight Disk Utility and use it to repartition. If you are on a PC use the search thing from the start menu and find a program called disk management (or something similar to that, you'll know it when you see it.) external drives are annoying. i kick mine into the wall periodically for good measure.
