USB drive scan error on RT-AC68U

[Maxxy13]

I've connected 5 TB Seagate Backup Plus drive to USB 3.0 port of my RT-AC68U. The drive contains multimedia library and is also used for Asus torrent app Download Master.
The problem is the router app marks this drive as having errors however Windows CHKDSK reports the disk is clean. Based on the log (see below) I suspect Asus app just can't handle such a large drive properly.

Here is the log of the disc scan from Asus app:

The issue is happening on the latest version 3.0.0.4.380_3831 as well as on a previous version.
Any ideas if this can be fixed or shall I just let it be?

Your disk is too big for your router to be able to do a filesystem check, it doesn't have enough RAM.

One suggestion I had, but never got any feedback on, was to reformat the hdd with 8K or 16K clusters instead. That may lower the memory requirements.

Hehe - depending on the use case - 64MB blocks might be nice - a 500MB video file there would only take around 8 blocks then... and a lot less metadata and inodes taken...

Thanks for the suggestions. Not sure if ever get to reformatting the disk considering it's already half full but I definitely will keep this idea in mind.

I think that's why I never got any feedback on my suggestion
