While using the Startup Disk Creator, I accidentally selected the wrong disk to erase -- my 1TB external formatted in FAT32. Once I realized what was happening, I pulled its USB cable mid-erase.
What I have now is unreadable. In both Nautilus and Windows, I get files and or folders with nonsense names, dates, etc.
The utility appeared to erase some data, but the majority of my data should (may?) still be there according to the figures in Nautilus.
Any ideas as to how I can fix this?
