Erase Unused disk space on Network attached storage (NAS) drive?


New Member
I am trying to erase unused space on my NAS but it is not showing in the dropdown. I have Eraser and my drive is mounted in Windows and it shows up in File Explorer with the proper drive letter.

I have looked over the help document and from reading page 7 it seems like it should be available.

My NAS does not have any quotas set for it. It is a RAID setup. I am on Windows 10 Pro

Is there something that I am missing?
