Rating : - Not a solid product
1. Only one of the three computers I have recognized the drive. All three computers recognized the drive when self powered USB hub was used.
2. Copied about 20 GB of files to the drive, then a couple files were corrupted and unable to delete.
3. The transfer speed was somewhat slow.

The return to Amazon process was painless, though.
