I'm using Eraser 22.214.171.12470 on Windows 10 and I was trying to wipe the free space (and wipe cluster tips) of my secondary hard drive. However, after being so close to 100% done it said that Eraser has stopped working and closed the program. Explorer then became sluggish for a little while and then I found the leftover files from Eraser which filled up the space in my drive which I then deleted and regained my space. However, checking my deleted files using Recuva I could still see file names for some files (which means it wasn't able to completely erase the free space). I want to know what caused the program to crash and fail to finish it's routine.
