My guess is that you have lost your data on this partition. Now, only formatting it |:/ Unless michaaaa62 has a better idea, I would try now Code: mkfs.vfat /dev/mmcblk0p1 this should wipe out everything that was in the 27gb part of your phone and make it work |:/ You could try other tools to try to recover the files that were on that, but you looked like they didn't matter after all... and then, just like michaaa62 said:
mkfs.vfat /dev/mmcblk0p1
