Using Macrium Reflect yesterday to clone a large hard drive from a failing hard drive to a new one. After the process completed, the log says that it completed perfectly fine without any issues.
After checking, yes the partition it copied was exactly the same size but the size of data it copied over was different by a substantial margin. On the original drive it was a 4tb partition (3.63tb really) with an amount of 545gb free, on the new drive after everything finished it has about 440gb free. Which is about a 95gb size increase.
Originally I thought it might have some sort of additional partition in case the clone failed at some point to start back up but there’s no such thing I can see in the Windows 10 Disk Manager.
Any ideas why or if I should be worried or where that data increase came from?
