If that's the drive, then that's not looking good for getting anything off

It turns out that the device uses a "special" filesystem.  I recommend making 
a copy of the hard drive and working with that.  Here's a script that looks 
like it can get the files off:
https://gist.github.com/joemck/483969

Much thanks for your help on this.

Some progress, but no recovery yet. The script does run for a while, the 
ZIF caddy light blinks like a typical drive light, and then it exits 
after a minute or so with the following message:
Traceback (most recent call last):
  File "/home/pyz/projects/Documents/VideosMP3s/ZenRecover/zenrecover.py", 
line 251, in <module>
    raise "Could not find the root inode"
TypeError: exceptions must be old-style classes or derived from 
BaseException, not str

From reading the python script, it requires four command line arguments. 
The first of these, the argument for the disk, requires an offset for 
the filesystem start.

So far, I've used /dev/sdb but have not specified an offset since the 
brief help screen indicates that the default offset is 20M.

I'm uncertain if this (not specifying the offset) is the cause of the 
error.

Thanks again,
