Hey all. A MicroSD card just went corrupt in an RPi and I'm wondering if it can be salvaged or reformatted. I can read from it no problem (two partitions, /boot is FAT and / is ext2). But it appears that the thing appears to the reader as enabling hardware write-protection, as if I had engaged the little slider on a regular sized SD card. Any suggestions? Both Windows (sdcard.org formatting tool) and Linux (dd) refuse to write to it, and the "dirty bit" can't be cleared from the boot partition. Any suggestions? Or is the card toast? Thanks! -- Evan Leibovitch Geneva, CH Em: evan at telly dot org Sk: evanleibovitch Tw: el56
Supposing it's corrosion in or around the wee write protect switch, there would be little to be done about it. My eyesight is nowhere near good enough to consider a hardware fix to something so tiny. I'd count myself lucky to be able to recover data from the card, replacements are cheap and hardly a giant travesty against "green" dogmas.

Try in a digital camera, and use its low-level format option. If it won't format, the flash controller's toast and it won't be worth salvaging. cheers, Stewart
