Hello everyone,

Just got DDWRT working on my WRT3200AC (DD-WRT v3.0-r44715 std (11/03/20))

I can successfully mount my 14tb drive but whenever I try to do any write activity i get an I/O error, even when doing something as small as creating a new folder. Everything seems to work fine with other sized hard drives. This did not happen on the original linksys firmware. I've searched for other people with this problem but can't really find any. Any idea how to fix it? I've attached some photos and the text from the auto mount. Let me know if there's anything else you need.

I managed to fix it myself by changing the filesystem to EXFAT. I tried other 14tb drives formated as NTFS and they also didnt work, but xfat works perfectly.

Use EXT4 or ZFS

Agreed. EXT4 has worked great for me on a modest Seagate 4TB magnetic drive that will soon be replaced with an 8TB. I also added the UUID to the "Mount Partition to /jffs" field since I use the drive with miniDLNA as well. Haven't played with ZFS yet over DDWRT on my router so I can't speak from personal experience as to how that file system performs on the 3200ACM, but based on my limited reading sounds pretty powerful and useful for large nas volumes!

Reset after any large build jump this being over two years. If upgrading from webUI ignore the dropdown option.
After successful upgrade: webUI administration to factory defaults or nvram erase && reboot from Telnet as root.
