Possibly OT - File Permissions issue

[DrTeeth]

N66U - Merlin's 374.41

Flashdrive in router as source for DNLA server. Drive has been formatted EXT2

I have run sudo chmod 777 -R /dev/sdb on the unmounted drive on a Linux machine. I also tried sudo chmod -R 777 /dev/sdb.

When I try to delete a file on the flash drive, I get the attached error on my windows machine (using Ext2Fsd 0.51.exe as driver).

Is the command incorrect? I have not added any files since running the command.
TIA

Update:- I managed to sort this stumbling though the GUI of Dolphin. I think I set all group permissions to allow all actions. But that is cheating. What is the correct command line command? The whole drive is /dev/sdb, there is no partition sdb1.

Did this work in the past? Seems to be a Ext2Fsd problem. I'm assuming you selected "Enable write support for Ext2 partitions".

The drive must be mounted, otherwise you will only set the permission of the mount point itself, not the content of the disk.

IIRC, the selection is for "Enable write support for Ext3 partitions".

Thanks Merlin, more experimentation needed here.

I've never used it myself, but according to this there are separate options for ext2 and ext3.

I'd assumed you meant that you had unmounted it from the ASUS and remounted on your Linux machine before doing the chmod.

You are correct, my bad. Option for EXT2 write was enabled and it works.

I did not mount it on the Linux machine. I will try again with some further testing. I did achieve what I wanted the the Dolphin GUI, but i would rather use the command line - it's more satisfying.

Thanks to all for your help. It's much appreciated.
