This info may help you if the following is true:
- up until now you?ve had no issues when using your sd card
- all of a sudden you can no longer write to the card, perhaps along with an error message being reported that indicates the sd card is mounted read-only
This is another one of those situations where it is not necessary to take extreme measures such as doing a complete reformat, or outright replacing the card?as suggested in the many threads on this subject.
Here are the facts. Your sd card?s file allocation table (FAT) has some kind of error. It?s an android-thing that crops up once in a while. Because of this FAT error, the card automatically gets mounted read-only, and no matter how many times you go into settings and try to unmount/remount the card, it is to no avail.
SOLUTION
Fix the FAT
- connect device to your PC (USB connection) and make sure it?s set so that you can copy files to/from your computer (on my device in the notification panel there?s an option to do this under ?USB connected?)
- on your pc, open windows explorer (or click on start->computer), then right click on the mapped drive to your sd card ? you may have to wait a minute or two for the mapping to take effect
- select Properties
- select Tools
- select Check now? (for error checking) to automatically fix file system errors (no need to deal with bad sectors at this time)
- when completed (takes a minute or so), the FAT will be in working order once again. No files are deleted during the process, so no need to worry about that.
- safely disconnect the device from your pc, at which point the sd card will now be mounted read-write and you?re good to go
