Being quite the novice, not sure if this normal or not. After running eraser and viewing the report, I find that there are probably at least one thousand instances that eraser failed to overwrite files that actually have names. Confused because I thought eraser only overwrote "unused" disk space? ( yes, I know that unused disk space is probably old, already used disk space.) Are so many overwrite failures normal? How do I know that these failures do not contain sensitive data? Please, will someone school me. Any and all insight is so greatly appreciated. Thanks!
