File format changing to ext2 ASUS ac68u

[unique904]

im having an issue with a USB Flash Drive and my router for some reason its changing my file format to ext2 from ext3 and showing the error below

also i have just formatted it back to ext3 and iv ended up with it back to this

ASUS: Superblock has an invalid journal (inode 8).
CLEARED.
*** ext3 journal has been deleted - filesystem is now ext2 only ***

ASUS was not cleanly unmounted, check forced.
ASUS: Inode 8 has EXTENTS_FL flag set on filesystem without extents support.


ASUS: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
(i.e., without -a or -p options)


I'm sure this might be simple to most experienced users but i haven't a clue what i need to do to fix this issue.

im on merlin's latest firmware too and its a 64gb usb 3.0 connected to the USB 3.0 socket
and just to add i have used a 32gb usb for over a year now without an issue so i dont know if thats a factor with the size

If the error is not causing any problems, I would disregard it.

You should be running ext2 on flash media anyway (ext3 writes to disk more often, thus killing flash drives sooner). Ext3/4 both support ext2, so you should really be using ext2.

The main difference between ext2 and ext3 is just the journal. For some reason your journal gets corrupted, so the kernel simply deletes it.

Make sure to always use Eject before doing a manual power cycle of your router, or unmount any mounted partition before unplugging it from a PC.

For a flash device, it's probably a good idea to use ext2 instead of ext3 indeed, due to the extra writes involved in maintaining a journal.

@RMerlin - does this apply to 1TD WD USB, as I remember I was advise to format to ext3/ext4 the first time I wanted add it to the router. Reason am asking is - if ext3 kills USB I might then revert to ext2
thanks

That 1 TB WD isn't a flash device, so ext3 is fine.

The choice of file-system (ext2/3/4) is important for the type of media the drive is, not the type of connector (USB).

If the drive is not a type of flash-media, ext3 or ext4 is a better choice. Certain routers have no ext4 support, so do your research before choosing.

i ened up formating it to ext2 and starting again.

i now i a different error which iv included below.
i did a scan of the drive to see if there was any faults using minitool and it came back clear so i dont know what the issue is if any.
before i had formatted tho pyload kept breaking and i had to restart the router or start it in putty, iv only just installed everything again so dont know how the apps are behaving yet so dont know if this error is causing any issues yet but id still like to know how to get rid of it if possible.

I personally ignore the warning, but if you want to avoid the warning you need to unmount the drive before rebooting the router.

I do not know if it matters, but I always use the software bundled on the router to setup the file-system on drives, to avoid any unforeseen compatibility troubles. My usual procedure is to run wipefs and/or "dd if=/dev/zero of=/path/to/drive", fdisk, mkfs, and finally fsck.
