Hi, I got the same problem than mareregu, but I have check the firmware that cause my problem... this firmware it was in the disc that came with the MP4... it results that it was for other MP4 from the same company... the MX767, and this MP4 aperantly it has a Hold function that is on the firmware that I use... an this is what is doing that my MP4 its apparently Hold, what means that is blocked and it is in "read only"... I suppouse that we need to find the way to format manualy the memory... or turn off the Hold function that has the firmware... at least in my case... I HOPE WE CAN FIND THE ANSWER WITH THE HELP FROM THE USERS OF THIS FORUM...
