I downloaded the iso before you posted at 2.00am last night!, the iso i'm using is mfstools2.iso downloaded from http://mfstools.sourceforge.net/blindlemon said:Full marks for initiative - but I provided a link to the recommended CD in the very post you have quoted!
TiVo drives are byteswapped, so to see the partitions listed at startup you need to boot in byteswapped mode.
Try the CD I linked to.
Edit: Doh! I knew I shouldn't have gone to make a cuppa in the middle of writing a post!
Which is the recommended cdrom from the Hinsdale guide, I've just checked. Both cdroms are the same, just different links to the same place.
I didn't know, I had to boot in byteswap mode, I assumed the cdrom was setup by default!
