Re: SD card locked

It didn't work with my card as the global readonly bit was set by the RaspberryPi during one of the reboots. The card become a ROM basically with no modification possible. So no formatting in the camera or using superuser account was effective. From OS level it tried to write over, but the SD physic...

Re: SD card locked

I have tried to do the format in two cameras, but it hasn't succeeded. I think that Raspbian has changed the permament write protection bit on the SD card and now it's the SD card hw blocking the write attempts. Second card from Goodram started to behave exactly the same way after several reboots ca...

Even...

Re: SD card locked

The card is not locked by a physical switch/slider. Sliding it to "locked" position returns other error messages. It looks like some sort of low level security mechanism got engaged preventing the overwrite of MBR/partition table. Maybe NOOBS has overwritten some part of SD card which locks this are...

SD card locked

I have tried to "low level" reformat my 8GB SD card after using it with NOOBS 1.1 using multiple methods, but without success. Windows format certainly doesn't work because the card has got multiple non-Win partitions. Still, even low level formatting with SDFormatter returns "write protection" erro...
