Make compressed sd card image - Raspberry Pi Forums

-

hi,
use 2 tools create images of raspberry pi sd cards on linux use dd, , on windows use win32 disk imager. both programs save uncompressed images of sd card computers hard disk. hasn't been problem until when bought couple of 32 gb micro sd cards amazing price of £12 each. working kodi , open elec @ moment large projects need space. thought had better sd card after bricked system custom electronics attached gpio!
wondering there program can make , read zipped image files don't need lot of working space on laptop hard drive. both programs read , store unused space on cards shouldn't necessary.
next tried rebuild sd card partition after using tar store files on original card, didn't work , resultant card partially boot.

advice or help
