It is the lacie 250g, not booting up

I'm giving you the same info as previous inquiries. Take a look here, problems are explained- unfortunately they don't suggest any easy fixes. http://www.dataclinic.co.uk/data-recover... These external drives, according to this site, and my own limited experience, are merely a standard drive in a housing with the proper adaptive circuitry for USB/Firewire connection. A couple of possibilities: open the housing, check the connections to the drive. I've seen one drive where the IDE interface cable wasn't seated properly. If you have some tech savvy, you could remove the drive and hook it up in a standard desktop PC, then see if it can be accessed. If what the above link explains is the problem with your drive, a simple solution looks bleak. You might also look on the 'net for drive diagnostic software. If you do open the case, note the drive brandname (Western Digital, Maxtor etc) and go to their respective website and download their diag. software. Unfortunately, none of this may help you get your data.
