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.

1) A corrupt SD card:
Deftone said:
SD cards, especially the Micro SD generation can be damaged very easily if you are not careful. Any physical damage to the card will or the gold contacts will cause it to become unreadable. 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:
Deftone said:
If the gold contacts are dirty in anyway, this will mean the device will not be able to read it. Using a finger can scratch the contacts and make it corrupt. 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:
Deftone said:
Removing an SD card from a computer without properly ejecting it can cause software damage to the card. 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:
Deftone said:
SD cards are enclosed in a small plastic casing that can be easily damaged if the card is left unprotected in a pocket, chewed on by the dog or stepped on. 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
Deftone said:
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.

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.
Thanks, this could be useful for my friend. He had a messed up sd card, hope I could get it to work with this.
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?

Hey,
This is because the physical switch on your sd is on lock. Try sliding it the other way. This will un-lock it.
If this fails you could try right clicking on your sd in my computer. Going to properties and then unchecking read-only.
Thanks for this, I will add it to the guide.

Hey There,
My best bet would be that your card is corrupt. Try formatting to other formats (FAT32). Then see if it works. Have you tried everything in the guide?
P.S: Thanks to all others for the support, I will try and answer any questions that you post here.
I've had some of these problems throughout the years but 90% of the times it was because on my microSD to SD converter (those SD cards that have a microSD slot in it) I didn't put the card very well or it was just one millimeter out. I really hate how these converters don't have that "click and lock" thingy when you put the microSD card, it's really helpful to keep them inside.
Also, this caused corruption sometimes.

i bought a 32gb transcend micro sdhc yesterday..went home, placed it in card reader, wrote backup on it, worked fine, i could r/w on it with my laptop..then i placed it in my phone [xperia sola 6.1.1.B.1.54 stock rooted bl locked], booted it and explored it using astro and root explorer, worked fine, i could r/w on it with those apps...the problem is when i open walkman there are no songs/albums detected, so i tried exploring an album and playing it via astro and walkman was able to play the song but just the one song i selected..its also the same with sony album app there are no pictures detected from external card, so i tried viewing a pic the same way i played the song, i was able to view the one pic i selected..there are no errors popping up, which is why its so confusing..i managed to make it work last night by clearing dalvik cache, but when i woke up this morning the problem began again..any advice?
btw on stock camera app i selected external memory as save location, when i open the app it says memory error but when i take a pic it can save there as well, i took a pic and album was able to see the new pic but not the old ones..am i missing something with permissions?i already tried changing the permissions for external memory using root explorer but failed, something about sd file systems not allowing permission changes..i already formatted it countless times to fat32 still the same..it really is working fine, its just that the apps arent able to access it for some reason or another..
update: i just restored my phone with backup from 2days ago and cleared my dalvik cache..its working now..my concern is if i restart my phone im probably gonna go over everything again..this is really weird
hope I could get it to work with this. thanks man

Hi,
I was syncing my sdcard with WindowsMedia player and then my TP2 or windows can't find it any more??
any ideas??
Usually when you connect youe TP2 in USB Storage Mode to the PC, the SD card is unmounted from your TP2. It should be remounted once you disconnect the TP2 from the PC. If it is not, soft-resetting the device should do the trick. Did you try a soft reset?

I have this same problem, and a problem it is, because it will not allow me to transfer files from the pc to the SD card, because it is disappearing from the windows explorer.
Or is there an other way to transfers files from the pc to the SD card (without taking out the card)
My old phone used to do this. I can usually clean the contacts and it will work again. I use a rubber eraser to keep from damaging the contacts.
I have a strange issue with my 4gig sdhc- after about 3 to 4 minutes card unmounts itself in my tp2 and isnt visibile anymore... any solution for this??
I had the same issue with a 8GByte card that used to work fine for months in my touchpro but was only usable in my touchpro2 for a couple of minutes. Never found the reason and had to buy a new 16GB instead, which worked fine eversince.
I had the same problem and found this solution:
Make a backup of your SD card, format the card in FAT32 and put the backup back on your SD card. Probably the problem will be solved!

As for the disappearing card, you may try this solution:

The Tilt is famous for the SD card disappearing, or more often, not showing up at all, when there is a filesystem error, I suspect the TP2 would be similar.
Run a filesystem check on the card. Put it in a card reader in a PC and scan the volume or whatever terminology Windows uses.

Well, I will give it a try, but something like the memory card should work right out of the box. If we weren't informed or aware of this site it would affect our opinions of the phone. The basics should always work well without mods. It's so easy to do and, from a hardware/software perspective, a minimum requirement.
Has anyone else come across the problem where the micro SD card seems to just stop being available to the phone? I'd say maybe once or so a day, anything that reads data from the SD card, such as the music app, stop working. If I try and play a song, it just hangs and does nothing.
I tried a search and somebody in the G1 forum had a similar problem but it didn't really contain any conclusions on what it is likely to be.
Anyone else had this issue? What is it most likely to be, the phone or card?
Thanks.
yeah I've had this occasionally with the camerea and seperately the 3d gallery software I installed.. have no idea why
Yea I've had that a couple of times actually. Just have to turn it off and on again and its ok, but its annoying.
Yeah, rebooting does sort it out, but it's starting to happen every day now, sometimes a couple times a day. If it's just a dodgy card or whatever I'd rather get T-Mobile to sort it sooner rather than later.
hmm a dodgy card.. included with the phone, that sucks
Backup your SD Card data and then try formatting it to see if that helps.
Cheers, will give that a go tomorrow. I might ring up T-Mob tomorrow anyway just to make them aware of the issue I'm having.
If I format it, will I be able to copy all the contents back on to it?

Yes, back it up to hard drive on your PC, then after you have formatted your SD card, copy back the contents from the hard drive to your Removable disk (SD card).
I've had this a few times Took the card out, reinserted and restarted the phone. Seemed to fix it, but it is annoying.
Sorry I can't remember when and how I know this.
But backup the card on your PC
Then format it in/with the phone and this should solve the problem I believe
I had killed one of my 16 GB card in Nexus one.
I found a problem that if i use Win 7 or Vista i must remove the device by using safely remove the USB device. Since now am doing this way i never had any problem.
Word of warning you could simply kill a card if you just remove a device.
My first thought was it has something to do with the USB connection. If you safely remove device in Windows - the phone 'prepares' the SD card.
I was having the same issue. I connected to the PC and mounted the SD card. I performed a disk check on the card and it found some errors which it then repaired. I then unmounted the card
I haven't had any issues since.
I formatted my card yesterday and haven't had any problems so far. thanks for the advice.
I ended up replacing the card. All of the previous advice didn't work for me or if it did it didn't last. I reckon there was a bit of a dodgy batch supplied by SanDisk.
~Since replacing I've had absolutely no problems whatsoever, it used to happen at least every 48hours. Very annoying when you try to take a photo and it tells you there's nowhere to save it.
I've been having problems too when taking pictures, which is really annoying!
And i'm not sure whether this is a related problem or not, but it could be...when trying to receive a file over bluetooth it sometimes says it doesn't have permission to receive the file or something along those lines, could this be the SD card playing up?
I'm on T Mobile, would they replace the SD card?
Not sure if it is the same reason, but I had all kinds of problems including the one you've described.
I'm on Orange, they told me that my SD card wasn't covered by Orange Care (the orange phone insurance). I said I didn't have Orange Care anyway and that surely it comes under the 12 months manufacturers warranty. They said pop it into the shop which is a bit of a drive and would cost me more than the value of a new card to get there.
At the time I wasn't certain it was the card as I didn't have a 2nd to try it with. Given my problem was very intermittent I decided the bother of going into the shop - it wasn't worth it for a £5 card. Now that I've bought a new one that works perfectly, I'm going to head into the shop with the old one next time I'm passing. The problem is I don't really need it replacing now! You could always lie and tell them you've tried your friends card at home for a couple of days and it worked perfectly?! No harm in trying.

Mhh - maybe I've had luck, but I use my over 1 year old 8gb cl6 card from magic/mt3g and never use that win function while unpluging anything (not while data transfer). So maybe depends on quality or manufacturer?

I hate to say it, but it will happen again. Have card reader or other phone prepared, just in case your sd card stops working totally
Hey guys, I had a question regarding my micro SD card. When I had my phone, it would randomly eject (Alpharom CM10, I believe). About a week ago, my phone broke completely (screen completely black out: the home button & others on the bottom wouldn't turn on), so I just kept the micro SD card to use it for something else later. When I stuck the Micro SD into the adapter & into the CPU, it read the items, but I can't seem to mess with them UNLESS I lock the SD adapter. I can copy them if the adapter is locked. If I unlock it & try to open a file, it freezes the whole CPU for a few seconds while it tries to read it.
I've made sure the Adapter has the Lock switch up while I try to format it. I've attempted to check if it is Read-Only through Computer>SD>Right-click>Properties, but no option that says Read-Only is available. I've downloaded a couple of programs, including the official SDFormatter program & they all say it is still Write-protected. I can't think of any other way to format it. I've even tried the scotch tape over the Lock switch. Maybe you guys can help me out? I wanted to use the SD for a tablet I expect on getting in the near future.

1. You don't seem to talking about our device - there's no "Alpharom CM10" for Epic 4G SPH-D700
2. I have no advice for you apart from buying a new card. Since you can at least copy out data, it'd be best to try a switch. Or why not try luck with another card reader that DIRECTLY reads MicroSD instead of from an adapter...

My bad. I just checked. The ROM is called Avatar ROM.
And yeah, I was afraid of that. Well, who knows what even caused it. The computer won't even allow the "Check for Errors" option. I will most definitely try another card reader when I have the chance.

I have 812 pictures in my Camera album on my external Toshiba 32GB Class 10 SD card. When I first got the phone in December, everything worked great, even after transferring from my EVO 3D. Now, whenever I try to access my stuff on my SD card through the Gallery app, it just freezes. I can hit home and exit the app, but back doesn't work and I cannot scroll anywhere. I can still access pictures via ASTRO and save stuff on to it..I just don't anymore, in case it goes corrupt. Any solutions? I tried searching, but no one seems to have the same problem as me..
Lol. Sounds like a simple cache issue with the gallery. Go to settings, application manager, all apps, find gallery, try clearing cache, and if that doesn't solve the problem, delete data. This will not delete your images. I think it may or may not delete your thumbnails. Just scroll over the images again and a thumbnail is remade. Nothing will harm your photos.

hmmm... I would normally say that the 800+ images in one gallery might be the cause of the problem. But you say that it was working fine previously. Even then, I'd recommend to split the images into different folders (maybe based on month they were taken) to minimize the amount of thumbnails that gallery has to process and look through.
I'm assuming you've done the MA6 and MB1 updates. Perhaps upgrading the phone to 4.1.2 caused this? I haven't heard of anything similar on XDA, but I'd stick with kkarson's approach and clear cache from the gallery app. Hope that works for ya!
Already tried clearing the cache and data from the Application Manager, but still the same results. I have a folder of old camera photos from my EVO 3D with 1780 photos in it, and it opens and I can view the photos perfectly fine, with no lag or freezing. But when I open the "Camera" folder on the ext. SD card, it just freezes and I have to go back to the home screen. I just upgraded to MB1 today and still the same results..

Maybe there's corrupted files on the SD card causing the phone to choke when it tries to read them. If you have windows 7 or XP you can put the card in your pc, (with a card reader or usb card reader), then right click on the card and choose properties. Select the tools tab in the properties box. The first option is error checking which will scan the disk and fix errors (if fix errors is checked). However, if there are corrupted files on the SD card it might be going bad and should be reformatted.
I have the same issue. I havent found a fix. I even formatted my external SD card.. didnt help.

But if my phone ever random restarts, or suddenly locks up, or I notice media is using a lot of battery, I know if I run scan disk on the card it will show errors. It lasts for a few weeks between formats.
There are also tons of posts from people that have had sd card failures on this phone (also with new cards).
Scan of my card after phone acted up.

I bought a new class 10 PNY card today. Once I get some pictures on it, I guess we'll see if that was the issue.

Dont worry you're not alone, theres a thread in general that had a ton of posts and the thread title was "If your sdcard failed on you, what recovery were you on?"
Many have had to purchase 2 or 3 cards until they got one that didnt go bad or corrupted. If you got the sdcard (the one that failed) very recently, you could call the manufacturer and tell them it failed on you, I'm sure they would send a replacement because I've seen others do it and they got their replacements in a timely manner

Well, the new card doesnt work any faster than the old card. At this point, Im thinking its not the card.
I guess I'm just gonna have to get a new card....this one is only 6 months old!!

This isn't the section for the S4.
In August, I bought a 128GB PNY microSD card. It lasted almost two months, and then the tablet started acting funny. It would randomly unmount the card, it couldn't find my music files, and apps I had moved to the card would just disappear. I assumed the card was broken, so I eventually replaced it with a 128GB Samsung card. It's worked fine until the other day, when it started exhibiting the exact same behavior. I haven't been able to fix it.
I've tried formatting them both, but nothing seems to work. Windows can see the cards and the contents, but it's not able to format either card - it reads them both as write-protected, even though they're not. The only thing I can think that might cause it besides my tablet is Link2SD. I use this to move the large app data to the card since I only have 16GB of regular space. Could this be causing it? I'm at a loss, and I can't keep buying new cards. Any help would be greatly appreciated!
I regularly read this forum and this is the first time I've heard of an issue as described. I bought a a cheaper 64Gb mSD card and used it with my Tab S day one. I've never had an issue. Could be you just have been unlucky? Were your cards from recognized brands? I suspect that the larger GB cards have lower yields so you need to buy a better quality card.

I definitely won't rule out being unlucky, it's definitely in my blood. I just find it odd the exact same thing would happen to two cards, months apart and with different brands and purchasing locations. PNY isn't super awesome, but they're not garbage, and Samsung is fairly prominent.
Samsung phones and tablets are occasionally said to be sd card killers. The GS3 definitely was, killed like 3 cards with the same result as you got.
Sometimes I feel it also affects certain sizes of card. The GS3 ate 16gb cards, but not 32gb cards. So it's quite possible that a different size card may have a longer life.
Not saying this has any base in research, just my experience.

I've read this on other forums as well, specifically the GS3 part. I wish there was a way to be sure. What happened to destroy the cards?
I am using a Samsung 64GB and Link2SD. Haven't encountered any issue so far. But on a related topic, I managed to destroy a 1 year old Sandisk USB drive yesterday while trying to format it as NTFS. Now Windows won't recognise it al all. It could just be that the flash memory had defects to begin with.
Does Windows make the bell sound when you insert your microsd, if it does you should be able to recover it, if it does not and you have checked the reader is working the microsd might be dead, if you have an sdhc adapter see if a camera or any other device will recognize the card, if it does format it in that device then see if windows will see it, I had an 16GB microsd a few years ago completely die when i froze while i was copying music to my phone, nothing would recognize the card after that it was totally dead, and i got a refund.

Windows does recognize the card, and I can see the contents of it and copy all content OFF the card. However, trying to format it just tells me the disk is write protected. I've done everything in my power to try to unlock the disk, including third-party programs and commands in the DOS prompt, but it's still write-protected. So bizarre!
I had the write protect problem on an card myself a few years ago, I downloaded an app that let me remove the protection and the card worked fine after that.
Does the write protection stop a camera from formatting the card, or only windows, as i said it`s been years since i had my problem.
Have you tried a partition manger app, I have used the one below for years, but i dont know if it will be blocked by the write protection as well.

I actually don't own a camera, the only things I have that take SD cards are computers and Android tablets/phones. I haven't tried that particular partition manager (Chrome won't let me download it - it says it's unsafe?), but the Windows manager and an HP one someone recommended both say "Failed to format disk."
I have uploaded the app i used, It years old so i most likely does not work but you can give it a try.

I would download partition wizard with another browser or force chrome to download it. Its a perfectly legitimate app which I've used many a time.
You need a low level format and partitioning software like that. Windows is useless on its own.
Delete the sd card partition, recreate and reformat.

I downloaded it through Edge, and everything worked fine. It even seemed like it was going to work, until I hit "apply". Then it sat and thought for a while, and told me there was an error with the format of the disk. Instead of trying to recreate 2 partitions, I tried to just see if it would format at all, and when I applied that change, it said it completed successfully, but the disk was still in it's former state - full of my files, fully readable, and definitely not formatted. I feel like this stupid thing is haunted.
So for this problem, can anyone give me an opinion on whether it's hardware or software based? Such as, do you believe this is happening because it's a Samsung tablet, or with a bug on their current Android version? I'm hesitant to keep putting cards in it, but I want to use my tablet!
Have you flashed or rooted your tablet? , are you on kitkat or lollipop?

It was rooted, but it was on stock 5.0.2. I used root to run Link2SD.
Link2SD only moves apps not music, so why did your music disappear, have you used any cleaning apps as they can delete files that you want to keep.

Well I had Link2SD moving all kinds of crap. It was linking games, books, comics, magazines...lots of stuff. My music didn't disappear - in fact, nothing did. It's all still there, only the tablet can't see it. My computer can see it, I can copy and open the files, but I can't write anything new to the card, and I can't format it.
It sounds like your tablet is loosing the location of the files on your microsd, I would say Link2SD is at fault, I would give the developer a email with the problem your are having and see what they say.
EDIT: I just read the reviews of LINK2SD and some people are reporting files are disappearing.

@greycobalt: I recently had Link2SD card stop mounting the 2nd partition (formatted as ext2, that is used for Link2SD).
I'm using a SanDisk 64 GB micro SD.
1) Did you have this same problem? Were you able to recover your app files when you put the SD card into your computer?
2) Oddly enough, I can see the files on the 1st partition of the card, which is formatted to FAT32 and I can see everything on that in file explorer. You said that these even disappear?
3) What file format did you have for your microSD for Link2SD to be able to link apps to it?
