This is what I did.

1. Plug HDD into Linux machine.
2. Run gparted and look at the drive. See a !, right click and Information
3. See: messages saying drive is having trouble and we should run chkdsk /f in Windows
4. Remove HDD and plug into windows. Using File Explorer, determine which drive letter it is, as it will show up shortly after you plug it in. For us, it was H:
5. Run MSDOS box (Start and run cmd)
6. Execute command

   chkdsk H: /f

   (Where H: is the HDD as we determined above)

   • This will likely take some time.
   • After it finishes, it is OK to run it a second time

1. Control Panel > System > Change Settings
2. Remote tab
3. Under Remote Desktop, select “Allow remote connections to this computer” and check the “Allow connections only from computers running Remote Desktop with Network Level Authentication (recommended)”.

• To set this machine's time to match remote machine's time
• net time \\machinename /set
