I had several of the free Internet 'hard drives' for several years: Freedrive, I-drive, and X-Drive. The first two I've used quite a bit to port work files between the office and home.
X-Drive announced they would be closing the service last month. Today I-drive did the same. I'm currently downloading a legal MP3 from there as I type, and I've removed any other files I want to keep from it, deleted those I don't.
It's a shame to lose another great resource like that.
