External USB disk status: Errors

[gatorback]

Errors below were observed, yet I was able to list files in the directory. The USB device is a Sandisk Cruzer flashdrive.

Errors have been detected on your hard drive. Remove any damaged files or use a PC to correct system issues.

/dev/sda1 was not cleanly unmounted, check forced.

The router power was cycled, yet the error persists. What is the next step to diagnosis so that an actionable remedy can be applied?

Go to External USB disk status in General > Network Map, select your drive and do a "rescan" under "Health Scanner".

If you're conversant in command line, unmount your disk and do a fsck.

If you're conversant in command line, unmount your disk and do a fsck.

And: If you HDD is big (like my one: 1 TB and quite full) the routers memory is to small to handle the fsck - you need to connect your HDD to a Linux workstation and do the filesystem check and repair there (as I did).

e2fsck -fv /dev/sda1

Not sure what triggered this message to require moderator approval, but anyhow...

Go to External USB disk status in General > Network Map, select your drive and do a "rescan" under "Health Scanner".

The 'rescan' procedure removed the error passage. @kvic: Thank you

For giggles, I tried this after the rescan (should have tried this before the rescan):
