The hub is recognised (3 port) , attached to it is 1) Ethernet dongle, but then it seems another 4 port hub is attached which has the keyboard attached??

Can you explain what your physical connections are and what is attached.

The rpi has a 5V 1.0A power supply
The USB keyboard is directly attached to one of the USB sockets on the rpi
The powered hub is attached to the other USB socket on the rpi
The hub has 4 usb ports
The usb hub has a 5v 1.6A power supply
The USB disk is attached via a cable with two USB plugs into the hub - I think this is necessary when you have a device that draws a lot of power. I have tried a traditional USB cable with no effect
The USB caddy has a label that states it draws 500mA
The keyboard works if plugged into the hub
A USB card reader and SD card mounts as an external disk if plugged into the hub - so the hub is ok.
So .. looks like to me there is sufficient power all round.

Quote:FAT-fs (mmcblk0p1): Volume was not properly unmounted: Is normal, it relates to the /boot directory (Which is FAT) on the SD card.

You need to be root and the disk unmounted, before you can perform disk utils on it.

Seeing as the disk never mounts is must be , err, unmounted. But what device do I put in the fsck command?

250GB should not be a problem - I use 2TB (NTFS) without issues.

I decided to give NTFS a go. I fully formatted the usb disk to NTFS on Windows, rather than a quick format. The format took an hour. The usb disk still works fine on Windows, in that I can copy large video files and play them, and does not mount on the rpi.

Quote:If anything, it could be your caddy - try plugging it directly into the RPi (If powered).

Tried that. No effect.

Quote:I think that if you move your USB connections around, it may just work

Have tried all sorts of configurations and still same outcome.

The point of doing a full format was to see if this would reveal any drive errors.
