Googling " 03:01.2 SD Host controller: Ricoh Co Ltd R5C822 SD/SDIO/MMC/MS/MSPro Host Adapter (rev 21) "

nets a whole bunch of linux problems threads

Another silly thought.  Dust-Off the card reader bay.  If the switch position detection is optically based perhaps dust or dirt could become a problem.

Could be what senses the switch position in the reader isn't working.
Are other cards mountable as writable, in the same reader?

On SD cards, it's not really a switch, there's no electronics behind it,
it's just an object that's felt, or looked through, in the reader.
Rather like the record protect holes in old fashioned cassette tapes.
