Sometimes when you insert a memory card into your computer , you may get
a message saying that the card needs to be formatted or that the card
is locked. This is called the Card Locked Error and can be caused mainly
by four reasons :
- Card is not compatible with your camera
- Write protection on the card
- A card error
- A problem with the card reader in the camera itself
this tutorial , we will cover these four causes and how to fix it, but
before you start these procedures, ensure if at all possible that all
data on the card that needs to be kept is backed up.REASON
NO 1 - Card is not compatible with your camera
cards were implemented , it was planned that the max capacity would be
2Gb. But in 2007 , the SDHC
card which ranges from 2Gb to
32Gb was introduced to the market. These two standards only differ
slightly and are even of the same design but a SDHC
will not work in a camera which only supports SD cards.
rule of thumb is :
- If your camera was made in 2007 it will not be
- If your camera was made in 2008 , it might be
compatible so check it out online (CLICK HERE) or ask someone on Fixya.
- If your camera was made after 2008 , it will probably
be SDHC compatible.
If you are unsure whether your
device is compatible , go to THIS SANDISK PAGE
use the compatibility tool on the right to check. Most products are
If you are still unsure , check the manual and
packaging of your device and look for the SDHC
looks like this :
normal SD logo looks like this one on the bottom and if displayed alone
means that your camera only accepts SD cards.

explaining the differences between SD and SDHC
NO 2 - Write protection on the card
SD and SDHC
normally have a function for locking or protecting the card. This is to
guard against overwriting or deleting data you did not intend to
delete. To unlock the card do the following :
NO 3 - A card error
- Remove the card from the camera or device.
- Locate the write protection or lock switch.
- Move the lock/protection switch to the top position
like on the card shown in the image.
- Reinsert the card into the device and use.
This error can mainly be diagnosed
by placing the sd/sdhc card into another camera for testing. If the
other camera works fine , it's your camera.
If the card also
does not work on the other camera , it's your memory card at fault.
is normally due to a failed memory module in the card and cannot be
REASON NO 4 - A problem with
the card reader in the camera itself
If the card
works in another camera . the problem is with your card reader in your
If you open you SD slot of your device and look inside
with a sharp light, you should be able to see on the left side of the
slot there is a little copper or spring steel lever switch.
switch work as follows:
- 1. When no card is inserted / no write protection ,
the switch is open and thus the protection is switched off.
- 2. When a locked card is inserted , the tab is
depressed into the opening in the sd card completing a electric circuit
and tells the camera that the card is locked.
to popular belief ,the little tab on the SD card is not an electronics
witch and does not physically influence the card operation itself. If
you put a locked card into a camera without a SD lock switch , you would
still be able to use the card normally.
normally happens is that over time this switch bends and eventually
closes the protection circuit even when the card inserted is not
It is difficult to fix this switch because of space
limitations in the SD card slot.
Look into the SD slot and if
you can see the switch , use a sewing needle or a toothpick to pull the
little tab back toward the base of the camera by about 1mm being careful
not to bend it. If this does not work , try bending it back by a little
bit . If this does not solve the problem ,try bending it slightly more
either to the back or to the front.
If this does not resolve your
problem , there might be a short in the switch circuit and the camera
will need to be disassembled to resolve this error. This should cost no
more than $50-$150 depending on the camera model.
