I have an external drive connected to my router via USB and mapped as a network drive in Windows.
I can access everything on the drive just fine, except for one specific folder.
Although the folder shows up in Windows Explorer just like all the other folders on the drive, when I try to access that folder specifically, I get an error pop-up as per below
If I try to access the network location using the UNC address, I get a rather similar error:
Trying to list the contents via command prompt also doesn't work:
If I instead connect the external drive directly to the USB port on my PC, I have no problems accessing the folder. This makes me suspect the problem is with the router configuration somehow, rather than with Windows or the external drive.
