Examining the hard drive of the FetchTV box is a easy, just unplug the SATA cable and connect it to a USB to SATA adapter.
The hard drive can be powered from the FetchTV box directly with it's internal SATA cable disconnected with no problems.
The file system is one partition containing a XFS file system, it is no problem to mount this drive using Ubuntu..
There is three directories on the drive; DATASTORE, PVOD and PVR. The root directory contains some interesting large files such as logs and settings.
In the DATASTORE directory there is some configuration files including the ISP specific config, all in plain text and easy to mod. Will post these files soon...
