I am currently working on a machine that appears to have suffered repartitioning of its hard drives during the Anniversary Update some weeks ago.
An external backup drive was repartitioned (and thank heaven we have discovered that a huge number of the files on it can be recovered from the space that's currently marked as unallocated - which is almost the entire drive) and it appears that the on-board disc drive was too. It has a C: and D: logical drive, with D: looking like it was once the recovery drive, that have been evenly split at approximately 225 GB each. I've never seen a recovery drive set up like this.
I am currently taking a system image before proceeding as well as letting File History go through a backup cycle for the user data files as well. After that is complete I am planning to use Mini Tools Partition Wizard to shrink the D: partition down to about 20 GB then take the space unallocated and extend the C: partition to consume that space.
This looks to be a very straightforward operation and my past history with various partition managers has been good. It's been a long time since I last did this sort of thing, so I wanted to check with those who might be using Partition Wizard on a regular basis to see if there's anything I need to be watching out for that would not be obvious.
I am hoping that after this repartitioning I might be able to get the Win10 AU to finally install, as I think it may have insufficient space on the C: drive during the install process to complete successfully.
