I'm upgrading from a 250 Gig SSD to a 1TB SSD. There's a handy migration tool from Samsung for this, and it has cloned my old SSD onto my new SSD. I did this via a eSata->USB connection. The old and new drives are now identical, named "C:", and are boot drives. (I haven't booted up or installed the new drive yet). My system is a desktop Windows 8.1 64 bit system.
The instructions now recommend that I remove my old drive and install the new one. I'm positive this will work, but I would like to retain my old SSD as a secondary drive. However, as it has the same drive letter and is also a boot drive, I don't see a way to let it inside the PC. As the old SSD Drive is an mSata drive, I would prefer not having to physically remove it. Is there a way to achieve my goal of replacing the old 250 Gig mSata SSD with my new 1TB eSata SSD as the new "C:" boot drive while retaining my old SSD drive for an extra 250 Gigs of drive space?
