"parted" and "df" are different commands with a different output.

- Open terminal, become root ("$ su -").
- Mount /system read-write ("# mount -o remount,rw /system")
- Copy the parted binary to /system/xbin ("# cp /sdcard/parted /system/xbin/parted")
- Change permissions to allow exec ("# chmod 0755 /system/xbin/parted")
- Mount /system read-only again ("# mount -o remount,ro /system")
- Print the partition details to a file ("# parted /dev/block/mmcblk0 print > /sdcard/mmcblk0.txt")
- Copy and paste the contents of mmcblk0.txt file from your sdcard here at forum.
