Hi Niels,

I think I've good news for you... in the Mac procedure description for restoring factory data, there is the hidden way to format the internal memory:
you have to power-on the G70 pressing "Top" and "Rec" button 'till you enter in the Internal Media Format environment. Then you can format the internal card pressing User Program 1.
This will solve your problem for sure.

Regards,
Rival
