Hello, I have just moved back from mac to pc. I have a 4 year old LaCie External drive that has everything backed up from my mac. I know most of it will be useless but I need my budget spreadsheet and want my photos, and stuff like that. Trouble is when I connect it to my new pc, Gateway One, is shows up in Devices and Printers but not as a clickable drive in My Computer. It's been tried on several other computers and laptops, all running windows 7, with the same result. Could this be because it was used on a mac? I thought it would at lest show up, then I could get off it what was usable. The paperwork that came with the drive says it's good on either pc or mac. Or could it be too old for windows 7? I did go to their web site and download drivers, didn't help. I'd appreciate any help or hints offered, I'm not very techy I'm afraid. Thanks very much. By the way, my son tried it on his works laptop, running xp. He's not allowed to install anything so he couldn't let the windows drivers run. We thought maybe it still might show up in My Computer, but it didn't.
