On Sunday my C Drive took a crap. Wouldn't boot. Tried repairing
it with the Win 10 install, but wouldn't work. Now I'm dreading the
SEVERAL DAYS of reinstalling programs...So I pulled my C Drive, which
is a 128 GB SSD, out, and put my new 1 TB empty drive in and did a fresh
install of Win 10. Once that was up and running I installed my C Drive
into my docking cradle and checked it. Everything was still there, but somehow
the Boot Sector had been wiped...so I backed up all my C Drive info and then
wiped the drive, did a fresh install of Win 10, then restored my backup and
everything is kosher again!
Moral of the story? ALWAYS back up...at least once a week...
