I have a Mac laptop and a Win desktop. I wanted to backup data from my Mac to my Win Hard Drive so I connected my hard drive through an external case and connected it via USB to my Mac.
I copied 40GB to one of the two partitions (non OS partition) and 50GB to the other partition (OS partition). Everything went fine and no errors appeared.
When I connected the hard drive back to my desktop I saw no copied folders, but the space was occupied.
I tried a
dir in the console, I tried software both on Mac and Win to see used disk space, Daisy Disk in Mac and TreeSize in Win. I see something like 100GB used, but if sum the size of every folder within the partition, I get only 50GB (in the OS partition) and I can't see where are the other 50GB. If I go inside the partition, select all folders and click proprties, the total size is 50GB.
In the non OS partition I removed all the files and formated it, but I can't do that in my OS partition and I'm missing 50GB. I've tried defragmenting and disk correction, seing hidden and system files and folders, deleting Shadow Drives, booting in safe mode with no network, re-connecting to the Mac via USB, etc... and nothing!
Does anyone have any suggestion on how to remove that used space without formatting that partition?
