I'm surprised MS didn't pick "LiveDrive" to start with. Although I'm sure someone has that trademarked as well, although Microsoft has plenty of cash to buy trademarks. You'd think, though, that they would also have plenty of lawyers to check out and register trademarks before they settle on product names, too.

Perhaps they should mine their own archives and try some alternatives:

Drive.NET, Visual Drive, ActiveDrive, Drive2014, Drive/286, Drive for Workgroups, MS-DRIVE?

Or better still, we know they own MS-DOS so how about "Microsoft Disk (Off-Site)"? Genius!
