![]() ![]() The cards were a 4GB and a 16GB, different brands. and yes there was plentry of space on the cards, prior to that I had resized for max use of microsd space. ![]() While using th "sudo rpi-update" command, at some point it gave several disk writing errors, and the process stopped. The only way to avoid the card becoming end of life is to restrict the number of writes to it, and to only do clean shutdowns and give the card time afterwards to finish its actions, including a possible internal shuffle of flash cell use, which can take several seconds. Yes, cards that decide to become write only do so because they sense they are end of life, and nothing can change they are end of life. The solution is to use the official SD-card formatting program from the SD-card association, as described in the help files:Īnother solution that often works is to format the card in a camera.īoth solutions however cannot help when the sd-card has set its internal read-only flag, because its end of life. In that situation it's game over even for a brand new card, and if that is the case the pi developers should make us aware of this issue and how to avoid it, if it cannot be fixed.Īnd yeah, I know the cards are dirt cheap nowadays, that's not the point. Information was written in an area protected by an efuse or some ireversible "read only" mechanism. Just as a theory, I'm not accusing anyone, I'm just trying to understand what went wrong but I think the PI during the "sudo rpi-update" process wrote something where it was not suppose to. ![]() Are those microsd cards lost forever? And most of all I would like to understand if this is not a Raspberry PI issue in the first place, rather than a "faulty microsd". I'm not an experienced linux user, and I wonder how can one recover from such a situation. using android format gave a "card defective" feedback so. usig Knoppix to resize, delete, etc the microsd. cleared the "read only" attribute using the command line. Tried everything, with no results unfortunatelly. those cards are in permanent "read only" mode. The problem is I can no longer format, erase, whatever. While trying to install an XPT2046 480x320 GPIO display, somehow 2 micro sd cards got fk-ed. ![]()
