You're honestly the first person I've *EVER* heard of losing data from it. Now if we're talking windows98 with it's beta support of USB that's another story entirely.

There's someone posting here weekly about losing data to ZFS on a USB solution, no thanks. Not only that, the complete lack of cross platform support makes it essentially useless in my world. I would like to believe it has more to do with Solaris's support of USB than ZFS, but the fact remains it's a pretty glaring deficiency in 2009, no matter which part of the stack is at fault. --Tim
