Problem with EXT3 fs plugged to USB?

[gds]

I have tried to plug an old backup USB drive to my rt-ac56u router running 380.57 and earlier over the years and it never seems to stay accessible for any length of time. It continously thrashes and I see many errors like this in the router system log:

Jun 27 00:40:06 kernel: EXT3-fs error (device sdb1): ext3_find_entry: reading directory #4292610 offset 0

When accessed, e.g., with ftp, the drive contents do not remain accessible.
The drive works fine when plugged into a standard linux box, e.g., fedora, debian etc.
I have plugged a FAT formatted usb stick to the router and it worked fine. Is there problem using a usb drives with EXT3 file system?

Run a fsck on the disk, the filesystem might be corrupted.

Thanks. Will try that. But since it works OK on other linux systems, I have my doubts...
One question: should I run fsck.ext3 on the router or when connected to a std linux system?

Check the perms on that drive as well...

Best to run it from a PC.

snbforums seem to be down before I saw your reply. Anyhow, ran it from the router using fsck.ext3 (umount'd) and that seems to fix it even though it didn't show any problems. Thanks.
