My Raspberry Pi V2 running Jessie crashed today. As I watched the boot up afterwards it was full of errors relating to the boot SD, etc. I assume that SD card had gotten corrupted. I tried the "Restore" option for booting and that gave be errors also.
Next using HDDRawCopy 1.1, tried restoring a backup copy to that SD card. Same problem, will not boot and lots of I/O errors. I tried to format this card hoping that that would correct the failing areas. Using SDFormatter 4 I got a error message that the SD card (probably a NOOBs image originally) was locked, thus formatting was impossible. However, from Window 10 I can see the card and even create a TXT file on the RESTORE partition, so how can it really be locked??
I also tried using Windows to format with similar "I can't do it" results. I also tried a different SD card, also a NOOBs image, which gave the same results. Is there an issue for formatting a NOOBs SD card back to its full size?
Now I found another 8GB SD card and tried to restore my backup to that card, again using HDDRawCopy 1.1. This time HDDRawCopy says that the two 8GB cards are slightly different in size and throws a write error and shuts down (it also does that when I tried using a 32 GB SD card.). In the past I'm sure I have restored 8GB images to 16GB SD cards?
So at this point I'm wondering what I'm doing wrong. Why can I not reformat these SD cards? How do I recover from this Pi v2 crash?
I'm in the process of downloading a new NOOB image.
Would greatly appreciate any help or ideas about this. Thanks....RDK
