My FAT32 disk was showing gobbledy gook upon mounting, so I ran Disk Utility to repair the disk. It returned “FILESYSTEM MODIFIED” and now my disk mounts as though it were a formatted partition. I have run Deep Scan and am recovering files, and I am very grateful. I am just wondering if the filesystem information was permanently lost, because reviewing and renaming all these files is going to be inconvenient. I noticed that Quick Scan was not an option when I started Disk Drill.
Quick Scan on a FAT32 partition is only available if the file system is intact. If it’s corrupted, you won’t be able to find anything, unfortunately. So, generally, yes, you will need a Deep Scan. And unfortunately, when reading data from a disk in a binary mode, in 99% of cases the file names are lost.
