I recently moved from a hard drive to a SSD . Unfortunately, the Samsung data migration tool didn't move my second drive. This was not surprising, as I had used Ext2 Volume Manager to mount the Ubuntu partition I had in dual boot. The software told me that it would be empty, but I decided to go ahead after backing up my programs and data.

My current problem is that I have a drive U:\ that shows up in explorer, but not in Disk Management. Also, it contains zero bytes, so it is of no practical value. I would like to hide it, but using Disk Management doesn't work. I would prefer not to need to download a tool etc. Any ideas?
