This thread has been created to address the hundreds of "Ma SD Don't Work" Threads spawned in the Accessories forum. After seeing and answering many of these, I though it would be appropriate to simply create a thread for this.

Almost 80% of all of these defective SD card threads have common solutions. I will list these below.

You know your card is corrupt when the computer cannot explore the card. SD cards can be damaged by forcing them out of the device they are in. If your SD card has become stuck in your computer, camera, MP3 player or printer.

It is best to take the device to a professional to have it removed, rather than trying to force the card from the device using probes, such as paperclips or screwdrivers. If the casing for your SD card becomes damaged or you accidentally damage the inside of your card, you could lose the data currently stored on the card and render the card useless in the future. Also, once it is corrupt, you cannot even sell it for parts or use it as a paperweight because of its low weight.

2) Dirty Contacts:

Instead use a cloth, microfiber if you have one. The reader, (device) will also accumulate dust over time. Clean out the reader with an earbud. This may also solve this issue.
ADDITIONAL: Thanks to hb-kevin for mentioning that you can " clean the contacts with denatured alcohol. It's a cleaning alcohol that is perfectly safe on electronics such as computers, motherboards, and phone parts. If all else fails, try giving the contacts a gentle scrub with some alcohol and a soft toothbrush. "

3) Corrupt Data:

Removing your SD card while your computer is trying to read it or removing the card from a camera or MP3 player that is powered on could cause your SD card to lose the data that is stored on it and force you to reformat the card before using it again. Many tools can be found online to help you with this pursuit.

4) Casing:

If the casing for your SD card has become damaged, do not put the card into a device (it might become stuck). Instead, take the card to a data recovery center in your area and have a professional recover any files you might need from the card.

5) The "Write Protected" Issue

On many SD cards (not many micro) there is a physical switch on the side of the card. This is a write lock. This means that if the switch is up and locked, the sd will refuse any data trying to be written to it. As a result, no data will be copied to the card - if it is in a computer, you will get a popup dialogue notifying you that it is write protected, just flick the switch.

The write protection could have also been enabled in a computer. To disable it, just right click on the SD in my computer and then click properties. Then go to attributes. If "read only" is checked, uncheck it. This could be the source of your problems.

Please hit thanks if you found this useful.
Please read this before posting another SD thread.

If any further help is required, please leave it down below.

EDIT: Thanks to Cooleagle for making this a sticky. Because of the stick, many more people will see this first and not have to create a thread.

I've actually been wondering about this because I got a free one with a product I bought off ebay (don't remember what) and I decided to use it the other day but it won't read at all. Turns out contacts were really dirty. Thanks for this thread.

Hey,

Thanks for using the sticky properly. You said you just want it to work again. Have you tried everything I suggested? If so then please come back and tell me exactly what is the problem. Is there an error or is nothing showing up. Please expand. Also, if you can I would suggest trying to get a new card reader. But please read through my thread thoroughly before replying again. It saves us a lot of time.

Thanks


Hit thanks if you found the thread useful.

I just bought a new Samsung 16Gb Class 10 micro SD card to replace my old 2Gb card.

First thing when I plug it in, it says it is damaged, and gives me an option to format the card. > Formatted using the phone, the card does not show up. From storage I can activate the SD card as it is still not showing, and the same thing comes up, over and over again. If I plug in the old one, no problem there, working like a charm.

I inserted it to my laptop with the SD adapter that came with it, and it shows up just fine ( size 15Gb). Windows XP format tool does not allow format to NTFS so I looked forward, ended up downloading HP USB Disk Storage Format Tool and SDFormatter. I got the card formatted to NTFS, but my phone still is saying the same thing.

What can I do next?
