Thread: SDHC card "write-protected"

  1. #1

    Default SDHC card "write-protected"

    hi guys,

    i was doing the usual photo transfer to my lappie after a shoot when after i slot back the SDHC card into camera, screen indicates 'card is write-protected'.

    however, i didn't set any password prior. will be able to solve the problem by formatting the card?

    yup check the small switch at the side of ur SD card, might have accidentally push it to the "lock" position while inserting....

    Or the thing might have came off. I have one brand new Sandisk Extreme III SD disk that has a missing switch. When I tried to use it, it was write-protected. At the end has to go to exchange for another one.

    actually the swich on the SD card is not really a on/off switch for the SD card, rather it is just to trigger a catch in the SD card slot on ur camera. don't think i explained well, but if ur "switch" drop off, u just need to paste a tape over the hole n the SD card will work as normal (unlock), without the tape, with the hole exposed = lock mode.

    oops, switch yes.

    anyways, what tunge says is right, it works with the reader, rather than the card, i.e. the card does not have some magic built in function to tell the computer that it has been locked. the reader merely detects if there is something there, if there is nothing, it will refuse to read. so that is why tape works.
