great little cable, seems to work well . .. BUT . . . You may need to "partition" any new blank drive . .. If it does not "show up" on WinExplorer, but does show up as a disk on System Info . .. use Start Menu > Control Panel > Bit Locker > Disk Management find un-allocated space and put at least one partition there now that space will have a drive letter (like "E:") now there will appear a usable space in WinExplorer under the new drive letter you created.
