I had an earlier model of the fantom drive. I wanted a new one so ordered it hoping for a nice replacement. I ordered 2 at once; one works fine. The other had a large part (presumably the drive) rattling around in the case. I returned it and got a replacement. It ALSO had a large part rattling around in the case, but less so. I plugged it into my computer but the drive didn't spin, and it didn't mount.Serious quality control issues.
