Like my writeable "D" CD drive vs a non-writeable one? No, I don't think so...
Y'see, my "old" jump drive doesn't have all these control panels, etc, but with it, I just take a Word or Excel file, or a picture maybe, and either "save as" or "send to", choose (on the drop down) "removeable USB...", and the little light in the drive blinks and there ya go!
If I try that with this new one, it says it can't do it because it's a read-only drive, etc. Does that help? JP
