v376.47 here. Never seen this before:

I have a My Passport ext4 formatted drive attached with an amule client running.
Yesterday I saw two files stopped on amule and when trying to resume them I got error on both. Very strange. When tried to restart amule client it refused to load again complaining about config folder permissions... stranger indeed.

So, I unmounted the disk and now everytime I reconnect it again the whole router crashes and it does not come back to life until I unplug the disk.

I tested on both my AC68U units ang gor the same result. I surface tested the disk and founf nothing, but cannot test its FS.

Any ideas before formatting again the disk?

Use a Linux live CD to do a filesystem check (fsck).
 
Hi,

great suggestion. I did, and it fixed all errors. Disk is back now on the router running again :D.

Thank you!
