250Gb USB Drive:


MetaData folder size was less that 1Mb.
2Tb USB drive:





MetaData folder size was 55Mb
I noticed that upon mounting of the 2Tb drive, a log in pop up appeared. I logged in with my routers admin credentials and was able to access the drive.
I was able to delete files and folder with out issue.
I presume that the metadata folder and other hidden folders maybe generated by the router and needs to remain on the drive.
