Manually resize a SD card for your Raspberry Pi (version2)
Warning, use these instructions on your own risk.
When I tried to resize the 16GB SD card in the raspberry pi version 2 I got a corrupted file system and all other kinds
of nastiness.
So I decided to try to resize the thing manually.
First “”dd”” the image to the SD card.
Leave the card in the reader/writer and issue the following comands, replace the device for you own device
and use the units for your card.

And of course, don’t choose ‘resize’ when the rspi first boots 🙂
