I am currently running Raspbian on Raspberry PI 3 and the SD memory card I've been using as hardrive on my pi is somehow got damaged probably from using it for a very long time.
Whenever I boot or turn my pi on, on the display it says among other things memory location is not readable OR Failed mounting SD Card. Then, it eventually times out waiting at the Console Prompt. No GUI is loaded. Well, after this, I would power recycle the PI again hoping that Raspbian Desktop will be loaded. Desktop may or may not load. I power recycle it again. Eventually, everything goes through and Raspbian Desktop is finally loaded. I've done a lot of work on this Raspbian PI in setting it up. If and when the SD card finally FAILS COMPLETELY, I will loose a lot and will have to start from scratch building it back again.
I have thought about Cloning and I do clone PI's SD card using Win32DiskImager on window. This program is fantastic. However, when I try to clone the damaged SD Card, it fails and reports that some of the memory location is not READABLE. Even though I have all the files from the damaged SD card saved and/or backed up, I will loose all the setup and settings for a lot of programs I downloaded and installed.
So, my question is this. Can you backup or save the current session? So, I can save the programs setups or settings for installed programs.
