Micro sd adapter i keeps in camera it is shows card locked

SOURCE: sd locking

I had this problem also. To solve the problem I blew into the slot where the card goes and it then read the card. If dirt gets into the port it causes the sd card to lock. You may have to use a pressurized can of eletronic spray to clean the port.

It worked for me.

SOURCE: Can't unlock 4gb sd memory card

There's a tiny slide switch on the side of the card. Slide it to the other position and try again.

But one thing I've noticed is that you mention that the card is 4GB. As such, it's likely that this card is an SDHC card. There is also a possibility that your A540 camera is not recognizing the card as the SDHC format came out well after the A540 was designed.

If you're still having problems with your 4GB card, recommend trying again with a standard SD card (2GB or less). 2GB standard SD cards are very inexpensive, and can be found on Amazon for about $7 with free shipping.

And hang onto the 4GB card. It will come in handy again someday.

So you're having problem in your memory card?

Try this:
1. Take out your memory card from the camera.
2. There's switch to lock and unlock on the memory card.
3. Just unlock it, and put back your memory card.

Hope this help! PM me if you have another questions.

SOURCE: memory card won't unlock

First I know you've said you've checked the card's slide switch, but just want to restate this first for others with the same problem who may not know of this switch.

Check to make sure that you didn't accidentally place the tiny locking slide switch on the side of your SD card in the "locked" downward position. The correct "unlocked" position should be slid up toward the direction of the connectors.

If you've tried this, and it's still showing locked, it's likely that the locking switch inside the camera's card slot is stuck. If you look inside the slot on the side of the slot where the SD card slide switch would be, you'll see a glint of gold color on the side. This is the camera's lock/unlock switch. The other glint's of gold that you may see at the far end of the slot are the reader's connectors (ignore those).

Somehow, the locking switch is making contact and has become stuck in the locked position. With a plastic toothpick, or other skinny NON-METALLIC item, tap against this switch to see if you can jar open the contact to its normal unlocked position. Also try blowing compressed air at it, as some gunk may have worked its way in there, jamming it closed. Occasionally, reinsert the SD card to see if the issue has been corrected.

If repeated tries fail, it may be time to consider opening the camera to force open this switch (not recommended unless you have some familiarity with electronics). In this case please see the following (xscrewdriver, hope you don't mind me referencing your blog):

Troubleshoot:

Memory card is used by digital camera to store the photos it takes. Popular memory cards include SD card, CF card, xD-Picture card and Memory stick. For some reasons, memory card may get damaged on power shortage, or removal of memory card on picture shooting or viewing, or other various and unknown reasons. Usually, you will see error message like "memory card error", "card locked", "card error", or an error code on your camera screen and the valuable pictures on the memory card could disappear and be lost. Some cases, your camera or Windows may prompt you to re-format the memory card and refuse to take new pictures or view old pictures.

Solution:

Once you have your memory card damaged, it is highly recommended to stop further operations on the memory card (e.g. taking new pictures, or delete, format the memory card). Data recovery software like "CardRecovery" is able to recover the lost pictures in most cases.

First, you need to confirm your memory card can appear as a drive letter in "My Computer", which will allow recovery software to access and recover the lost photos. You may try to connect your digital camera to your computer, if a new drive letter appears in "My Computer", it is OK. Otherwise, you need to prepare a USB card reader. There are many card readers available in market (e.g. SanDisk and Kingston). You can buy one from Amazon or BestBuy.


Then, you may download and install CardRecovery to your computer. Launch it from Start Menu -> Programs -> CardRecovery. You select the drive letter of your memory card, and destination folder for save the recovered files. CardRecovery will scan your memory card and locate the recoverable pictures. The process is quick and easy. Usually it takes less than 15 minutes.

Can I re-use the corrupted memory card?

For data protection, CardRecovery performs read only operation on your memory card and it does not change the data on the memory card, so it does not repair or fix the memory card. If you need, AFTER you have recovered your lost photos from the card, you may try to format the memory card before re-use. It is suggested to perform enough read/write test before using it again to take new pictures. If you are worrying that the memory card is unstable and may cause further data loss, purchase and use a new memory card. Your valuable and irreplaceable photos are more important than memory card. Memory card is very cheap. A new 2GB SD, CF or xD card is less than $10.
