I backed up my data from Mydocs, umounted /dev/mmcblk0p1,
did an "mkfs.vfat -F32 -s64" (using the mkfs.vfat tool on my phone, I wonder if it's somehow patched by Nokia), remounted it, and am now restoring my data. (which goes much slower then backing it up, btw, about 4.8MB/s), and will try again in the volvo when it's done. *fingers crossed*

Oh and btw, as you can see in my filesystem info on page 1, the FS was already fat32, and fat32 works, we tried with an usb stick. So i make it fat32 again. It had 128 sectors/cluster, whereas it now has 64.
