SD Card The disk is write-protected. Remove the write protection or use another disk.

What do I do to remove the write protection?

I have a Palm E

Thanks,

Sara, look at the SD card closely and you'll see a tiny white "switch" on the side of it. When slid to the "Lock" position, your card has become "Write Protected".

Slide it back away from "Lock" and all should be well.

I tried that and it didn't work.  The only think I can think of if the Palm put a protection on it.  I can't not figure how to get it un-protected.

What kind of card is it? A game card or dictionary card?

AFAIK, yes these come write protected to keep from accidental erasure.

It is a SD-M512 and SD-M256.  I am guessing just foe storage.  I insert in into my computer and I can not add anything to them.  It says the above.  I used them in the palm.  Moving the slide switch doesn't do anything.  ARG!!

Just to throw it out there to make sure there is no confusion. When you are moving the switch are you sliding it across and then sliding it back and trying or are you sliding it one way then reinserting it, that is the way it should be. The switch has two settings locked and unlocked. If the card is set to locked it is "write protected" The palm devices have no way of "pushing" this type of situation to the card. If you are still experiencing this problem even on a computer then it is a problem with the card itself. You should see the card manufactorer.

Yes I tried moving the switch one way and tring it and then moving it back and tring and it still doesn't let me put thinks on or take them off. 

Thanks for the help,

These are rather small capacity cards.

What OS is on your computer and how new is your card reader?

  I wonder about something here.  I know that on floppy disks, it's up to the drive to detect the position of the write-protect tab.  A floppy disk drive has a switch or other sensor to detect this, and if that switch malfunctions, then a drive could falsely report a disk to be write-protected when it is not, or vice versa.  How does it work with SD cards?  Is there a switch or sensor in the Palm to detect the position of the write-protect switch on the SD card; or is it up to the SD card itself to detect the physical position of this switch, and to refuse to allow itself to be written if it is write-protected, and to electrically communicate this status to the host device?

  In the former case, the OP's problem could be caused by a fault in the Palm.  The switch or sensor in the Palm could be malfunctioning, and failing to correctly report the write-protect status of the card.

  In the latter case, you'd be correct.

  I suspect the latter case to be correct.  I've just made a careful examination of the SD slot on a generic card reader, and I do not see anything that looks like a switch or sensor in a position to allow it to detect the position of the write-protect tab, yet if I write-protect an SD card and mount it via this reader, it does show up as unwritable.

It is the SD card itself that determines the position of the switch. If it is falsely thinking it is locked it locks itself down and won't allow it to be written on. It is not determined by the device.
