I made an image as soon as I was done, because I had used a different
card to install Wheezy from the one I bought for the purpose. So I had
to image the replacement card and then write it to the original
It turns out that the SDcard image is gigantic! It holds 4-5 GB worth
of used space as reported on the command line:
pi at raspberrypi ~ $ sudo df -h
Filesystem Size Used Avail Use% Mounted on
rootfs 29G 4.8G 23G 18% /
/dev/root 29G 4.8G 23G 18% /
devtmpfs 460M 0 460M 0% /dev
tmpfs 93M 232K 93M 1% /run
tmpfs 5.0M 0 5.0M 0% /run/lock
tmpfs 186M 0 186M 0% /run/shm
/dev/mmcblk0p1 56M 19M 37M 34% /boot
But the image file is actually almost 30 GB in size and it seems
impossible to compress it any...
The spare MicroSDcard is one I used on my phone earlier but had to
change when I ran out of space and bought a 64 GB card instead.
So I guess it holds a lot of erased but not removed data (photos and
movies) that should be cleared first before I turn it over to anyone
Is there some way one can reset all unused sectors on the disk to only
contain 0xFF or Ox00?
That would make the image file compressible to a few GB and possible
