    Hello there,

    i have a weird problem.
    Take a look at the following output from a adb root shell with busybox installed.

    DF
    Code:
    # busybox df -h

    So these two calls show two important information:
    df is reporting memory block "/dev/block/mmcblk0p17" as 1.3G in size and 1.2G IN USE! mounted on /data
    du is reporting 56M in use for /data
    mount is not showing anything else hooked into /data

    So where is the missing 1.15G storage space that is IN USE!?

    P.S. I am unable to create an account here on the site. So any helpful information can be posted, i will monitor this post for answers.
