I own a Humax PVR 9200 from which in the past I have successfully extracted 
the.TS files via the USB socket to make DVDs.

I've recently purchased a very cheap (£50.00) Digifusion PVR for my den. The 
only problem with this is that it lacks any device for allowing the 
extraction of files from the hard disk, however browsing the net tells me 
that it is possible if I install the hard drive into my computer and then 
use a programme called 'syphon' to extract the files.

I've done this, however my computer informs me that the drive requires 
formatting and I get the same message when I select the drive in the syphon 
programme, has anyone got any clues which could point me in the right 
direction please?..  my OS is Vista.. TIA
