I recently cloned my windows installation to a new SSD, the partition on my old hard drive was 111 GB whereas my new SSD is 120 GB. I used paragon Paragon Migrate OS to SSD and told it to use the whole drive when cloning.
It appears that the clone did not work correctly as my the partition I am using now is 111 GB and not the 120 I had expected.
Both windows disk manager and Gparted report the maximum size of the drive to be 111GB.
The model of the SSD is a Kingston Hyper X 3K.
Where could this missing drive capacity be?
