Being new to this area I was hoping for some help as to why after running eraser on unused space local disc C the report shows massive amounts of failures (probably around 4,000 or more)
I use On Demand; new task; Unused space Local Disc C then "run"
Over writing method is Gutmann's 35 pass method

I'm not sure if there should be any failures after over writing unused disk space
A bulk of these have (Protected File) at the end of the log

Below is a random selection of what appears

Failed: C:\WINDOWS\system32\mmtask.tsk (Protected File)
Failed: C:\WINDOWS\system32\mmutilse.dll (Protected File)

These are locked system files, in other words don’t worry about it.

All quite normal. :D
