Has anyone successfully recovered a NOOBS card that says it is write protected? I have read numerous posts and solutions but still appears there is no solution other than the card is bad. It started when I used Win32DiskImger to install a new image file (Octopi). I noticed I still had the old Jessie Lite on the card. I have tried SDFormatter and it reports the disk is write protected (it is microSD so no switch) and have tried three different USB adapters (they do not have write protect switches either). Other tools like RMPrepUSB either appear to work (but don't) or give the write protect message.
I can actually edit a file on the card like issues.txt and when I reopen the file, my edits are there. But if I unmount and mount again, magically my edits are gone. I can delete files like bootcode.bin, etc and I get a warning that I am permanently deleting them and poof they are gone. But they magically re-appear when I remount. This is darnest thing I have ever seen. I can even put the card back in the Pi and it boots after deleting ALL the files on the root from Windows. Also tried a digital camera format. It reports I am using 16 of 32 MB and when I format (regular and low-level) it appears to work but when I go back to the format option I get the same message (I am STILL using 16 of 32 MB).
And did I mention that there is no write protect switch so PLEASE don't suggest I check that!!! Thanks in advance!
