Anyone ever have this or know of a fix (besides, I suspect, getting a new card)?
I have an SD card that has started occasionally popping up as "this disk is write protected" when I want to modify or save something on it. It's done it four times now over a few months, with the computer generally turned on at the beginning of the day and off at night. It lives in my main laptop and is only removed when I need to stick another SD card in the slot.
So far, if I reboot after getting the error, the card works normally again. I'm wondering if maybe the write protect switch is physically malfunctioning (which would mean "new card") or if this is some other kind of error.
All the obvious stuff has been checked - switch in proper position, files are not soft write protected, etc (I've copied the files to the desktop and they write fine there). Never had this happen on an SD card before, and haven't found much on the Googles.
Oh, ETA - the files are all in a large TrueCrypt file on this drive (the drive is not encrypted, I just have a Truecrypt file on it). Not sure if that has anything to do with it, given that I can write to them when they are moved elsewhere.
