Windows 7 File Explorer Deleted Files?

I wanted to consolidate data from other disks that I had so I could use those disks to convert an existing Windows 7 installation into a RAID array. So I hooked up additional 2 x 500GB disks that contained files and previous installations of Windows and a 1TB drive to copy the files I wanted to keep. These two 500GB other disks were used for Vista in the past and both had been used as primary hard disks (ie they both had independent OS's installed).After booting up, I proceeded to browse through the disks and decided what I wanted to keep and what I didn't want to keep. I had to change permissions here and there to get access to the old Vista directories etc. All well and good so far.I have C: (Windows 7 installation), G: (old Vista disk) and F: (another old Vista disk). For all other installs including the Windows 7, I used the same username. For convenience sake, lets call my username billgates.So, C:, G: and F: all had directories USERS/billgates directories.Following this so far?When I browsed to F:usersillgates, I was seeing files from that directory plus files from c:usersillgates even though the location in windows explorer was saying f:usersillgates
