ASUS RT-N66U is unable to read Ext2 and Ext3 filesystems

[GH0]

Build: DD-WRT v24-sp2 (04/07/12) mega (SVN revision 18946M NEWD-2 K2.6 Eko) & Big builds

I have two USB Drives (one a PNY 2GB Flash Drive, the other a Corsair 8 GB Voyager Drive). When partitioning to fit the Optware partition scheme shown here: ​http://dd-wrt.com/wiki/index.php/How_to_-_Format_and_Partition_External_Storage_Device

They fail to show up in the USB Services, and the output shows the following: --- /dev/discs/disc0/disc Status: Not mounted - Unsupported file system or disk not formated Status: Not mounted - Unsupported file system or disk not formated

Plugging the drives into my WRT350N & my linux server the drives work fine and are partitioned:

This seems to be a problem with the build as Fractal has mentioned that he can use NTFS perfectly fine.

this is the output of your WRT350N which works. okay. but we need the output of your non working device since we need some error messages to track down the problem. so basicly. what shows dmesg etc. use the telnet console to give us some more informations

If you need any more specific log messages, let me know. To be clear this is using the Automatic Drive Mount functionality under the Services > USB menu.

I have been trying over the past couple days to get the USB Drive mounted, and I have been unsuccessful.

The projected path:

root@Dark-Knight:/dev/scsi/host5/bus0/target0/lun0# ls -l brw------- 1 root root 8, 0 Jan 1 1970 disc brw------- 1 root root 8, 1 Jan 1 1970 part1 brw------- 1 root root 8, 2 Jan 1 1970 part2 brw------- 1 root root 8, 3 Jan 1 1970 part3 root@Dark-Knight:/dev/scsi/host5/bus0/target0/lun0#

Brainslayer, or anyone else familiar with this process, what other information needs to be taken down (besides dmesg)?

[GH0]

USB Services

[GH0]

Output of scsi devices, output (or lack of) of messages file

Hope this helps as well.Output of cat /proc/*
