there is something strange with some of them, most folders are ok, the files can be opened and their data is ok, but some (not the same folder, mostly random) shows the files, the correct size, no preview available and when you try to open one file from that folder it says invalid format. It can be a PDF, a JPG or a PAGES file. I opened some of them with hex editor and they are empty, no data, but the size is ok.
I used DiskDrill to recover a Time Capsule HDD that was not working well, after the recovery I saw all my files and believed that everything worked perfect because I tried to open some recovered files and they were perfect, so I formatted the HDD again.
Now I get this disgusting surprise, can anybody tell me what happened here? Were the files damaged and unable to recover? If so, why DiskDrill would make me think all files were recovered?
