How do you turn write protection of a sd card?

Answer 1

SD (Secure Digital) card readers go into 'write-protect' mode if there is a notch cut into the upper-left edge of the card. This is similar to the write-protect cutout on floppy disks, and audio or video tape.

Many SD cards provide reversible write-protection by means of a pre-cut notch, and a small sliding tab: Sliding the tab downwards (toward the position marked 'lock') exposesthe notch and activates write-protection. Conversely, sliding the tab upwards covers the notch, which deactivates write-protection.

But sometimes, even though set to the 'unlock' position, the sliding tab doesn't protrude enough to deactivate write-protection. In this case, placing a few layers of scotch tape over the tab can thicken it enough to allow writing to the SD card. Note: Care must be taken to ensure the gold contacts on the card aren't blocked by the tape!

Other cards that don't have a switch like this may use the default settings (configured by the device that it came with) to disable writing to the disk. Note: these other card types are probably set to be write protected by the device software that came with them (such as a digital camera and the accompanying software would figure that it is the only interface that will write to your memory card).

Virtually *all* USB devices that have onboard storage capacity will in raw form be seen by the computer as an added hard drive. You can check for this by going into My Computer or Explore (on IBM based pc's). If you can get to a file/folder view of the memory card you are asking about, try and set the (top level) folder properties and/or file properties to *not* be hidden or read-only. More information regarding file permissions can be clarified by researching file attributes.

In the case of my camera, there is an option to select and protect any images via the menu. I'm not sure all cameras do it or that the steps are the same. You can also insert the card into a card reader and write protect all images in one step. To me it makes more sense at that point, to copy those images to a PC or portable storage (preferably multiple drives - and best yet, have at least one disk or drive which can be kept at a separate location). Once the images are safely copied and protected, then clear the originals from the SD card. I carry a small battery operated drive with a built-in card reader.

Answer 3

There is usually a very small slide bar to one side of the card. You will need to slide that little bar to the other end of the opening. It is usually printed on the card which direction it needs to be in.

Answer 4

Its very simple...You just have to unlock the write protection mode of card reader which you are using for your SD card.
