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 (Jessie) card. 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@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 else. 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 to share. -- Bo Berglund Developer in Sweden _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
