That is what you get for living in a different time zone...
A bunch of new posts and no way to reply in a timely manner...
Okay, so the F10/F20 can only be upgraded to max 30GB because of the harddisk thickness. The one platter HDDs are 5 mm and the two-platter disks (40 GB and above) are 8mm.
Which is a shame, since the F10/20 is available in a dark color scheme that I like better then the silver only for the F40.
As for using a CF with the F10/F20 I have tried that and so far it does not work
The 32GB CF worked perfectly fine in a ipod mini, but in the Gigabeat it gets corrupted within a few hours...
I am still researching that, though.
Updating the Gigabeat F40 to a Zif HDD is a matter of about 5 minutes (the second or third time around...).
The adapter is available from
ESSkabel (ADA-HDD-1.8-ZIF-CF).
It is not a 100% perfect fit, but I have used one Gigabeat with it for about two month now in daily use.
It is especially good to hear that I am not the only one liking the SQ
