how to restart the usb ?

[GoNz0]

My usb3 hdd will not mount until it is unplugged and put back, then it shows straight away.

if there anything I can do in the JFFS to restart this and get the damn thing to mount on a router reboot ?

it does all this then shows unmounted

Well, lets see if this helps:
add to /jffs/scripts/wan-start

#!/bin/sh
sleep 15
/sbin/hotplug2

and make the file executable

chmod a+rx /jffs/scripts/wan-start

The sleep time can be de- or increased if that helps

Can you reboot your router and then post the complete log as well as the contents of /tmp/usb.log

 

[GoNz0]

I did think it would work apart from one rather large issue.

If I unmount the drive the command works fine.

If I reboot the router and try to mount the drive without replugging the USB I get the following returned (without mounting it)

It needs to be unmounted first then. WhatsThatCommandAgain?

 

[GoNz0]

logs attached thanks

I tried to run the unmount and it makes no difference m8

My USB Log looks about the same. --> looks OK.
Is your VERY BIG DEVICE attached to a hub?

 

[GoNz0]

nope, i did try a hub to see if that helped but it doesn't work at all.

I can see 2 problems.

1. The router isn't seeing /dev/sda5 when it boots up (although it can see /dev/sda1).

2. It thinks the disk has 512-byte logical blocks rather than 4096.

I think this is a common problem with disks with non-512 byte blocks.

Try:

/sbin/asus_sd sda5 remove
/sbin/asus_sd sda1 remove
/sbin/asus_sd sda remove
/sbin/hotplug2

 

[GoNz0]

nope, it didnt work.

 

[ColinTaylor]

Can you attach the log files again.

How about this:

/sbin/asus_sd sda5 remove
/sbin/asus_sd sda1 remove

rmmod sd_mod
insmod sd_mod
