(Guide/How-To) How to Fix a Non-functional microSD - Hardware Hacking General

This guide/how-to will show you how to fix your non-functional microSD card.
Things you need:​-Broken microSD
-Blackberry (tested with a Curve)
That's it!
How I came across this fix and some backstory:​Your microSD card might not really be broken. Just follow these easy steps to fix your "broken" microSD. The other day, I tried to flash a ROM from my external SD. In recovery, it said that there was no external SD mounted. I knew that wasn't true, so I took a deeper look in. I also tried to manually mount the SD card in the settings menu. I tried changing my ROM, trying putting the microSD into different devices, but no matter what I did, the microSD couldn't be read. I even considered returning to stock.
I was on Amazon, already looking at some new UHS-1 Sandisk cards. I figured I needed a faster and bigger card anyways. That was when I noticed a Blackberry Curve next to me. I hadn't tried putting the microSD in it yet, so I said to myself, "What do I have to lose? It's already not working. It can only make it better." I put in the microSD and voila! The BlackBerry recognized the card and asked if I wanted to format it. I hit yes and the BB formated the microSD with no issues. I put my microSD back in my T-Mobile Galaxy S2, and guess what? The phone recognized it! Another plus is the fact that with the BlackBerry format, there was only one folder. Normally, when you format a card in a phone, there are A LOT of folders. I just deleted the BlackBerry folder so basically, I had a completely empty card.
Formal Instructions on how to fix your microSD:​1. Put your not-functional microSD into a BlackBerry.
2. The BlackBerry should ask to format the card. Hit yes.
4. Connect your microSD to a computer. Open it up.
5. Delete the folder called "BlackBerry" (optional).
6. Your microSD card should now work fine.

It might not show up. My microSD only showed up in the BB. This is just if nothing can read the card.

This solution not for all cards If you card is password locked - it can help to format. If card totally dead - solution not applicable.

If you get *really* desperate, have stuff on it that can't be replaced, and have a few days to burn, you can also try to rip the bits from it using an Arduino (or any other microcontroller).
The easy part is pointing at address=0 and sequentially reading it a bit at a time, byte by byte, via SPI. The *hard* part is interpreting it as a filesystem. I know code exists for FAT32, but I'm not so confident about ext2/3/4 or NTFS. For those, you might have to come up with a way to get the raw data into a form DD can recognize.
The point is, a microSD card is pretty hard to physically destroy. It's one of the few devices we have left that can be low-level read by fairly simple means (in theory, you could probably read it with a 3v DC power source, a SPST toggle switch, two momentary buttons, a LED & resistor, a soldering iron, and some wire... one button for MOSI, one button for SCK, and the LED for MISO. Flip the switch to transition ~SS from high to low to reset the latch, and press away. Ok, maybe debounce it, too...
It wouldn't do you much good that way, but it's an example of just how easy it IS to rip raw bits from a microSD card. No real timing requirements (AFAIK, microSD timing is entirely static). Apparently, this is kind of how the first home computers worked, too...

I don't know. This only applies to people who have a BlackBerry. I guess you could try sticking your microSD in different devices and see if something pops up asking you to format your card.

More to the point how about doing some basic fact-finding first and finding out what errors the kernel on the device is reporting when it tries to mount the sdcard, then steps can be taken to solve the real problem rather than relying on magic and what some people might term as beginners luck! A good place to start is
Code:
adb shell dmesg

32gb micro sandisk not mounting ??

hi,just tried my new 32gb sandisk & it wont stay on,i plugged it in & it says i can safely remove & when i mount it it appears as 29gb and then vanishes again,ive erased the card but still wont stay & also restarted phone ??? any ideas ? is the card a duff ?
bloody hell now my old card is doing the samething & all my data,music & videos etc are not showing ?
none of my cards will stay mounted & ive factory reset also,they just appear & disappear 16gb & my new 32gb sandisk ?
notification keeps coming up to safely remove sd card
There is a little switch that clicks down when you put the back down. Be sure the back cover of your phone is all the way one or it won’t mount.
Also once you change cards your old card will not work in your phone again (data wise).
The phone seems to marry to the card then forget the old card. I learned that the hard way when I put a smaller card in while I rooted my phone (all I did was format the other card at that point). Then I put my main card back in all my games had to be reinstalled.
You can copy all the data files from one card to the other and the phone will recognize both properly

Not that I know of. Like I said it forgot my SD after putting a new one in and formatting it. So i'm guessing one at a time.

[Q] 32 gig card trouble

I have recently purchased a 32gb micro sd card. When I go to put new music on it, it shows from the pc side that it is loading on the external drive(g2 phone) and form the phone it says that it is on there. However when I disconnect the phone only the last album that I put on there stays and the music player will state that "this type of file cannot be played". I have formatted the card through the computer and to no avail, it acts the same.. I did format it on the Android and it worked, temporarily and could load music from my computer for a few days, then it stopped. I am clueless as to what is going on with it. p.s. I tried placing it in a card reader and it did the same, but i did not format it first that time. I seem to think the android is placing a bad file on it causing all these issues. (again I say this because when I format it through the phone it will work temorarilly) any help would be great, I really want toload my phone with music.

Put the same file on a known good SD card. If it stays, it's a bad card. Most of the time the company the card came from will replace it for free (like Wintec did with a bad card that couldn't handle an EXT4 partition).
It is not just one file, it can be multiple files, like I stated in the other thread (I apologize to do two on here, but I rarely have to ask for help, I am usually able to figure the problem out, but this one has got me) I have checked the card with h2test and it states that it does have 32 gigs on it but that the card is corrupt, I have formatted the quick way with sd formatter. What puzzles me is that at one time I was able to load more on it and now I cannot. I feel that there is a fix, I am just not finding it yet.(okay im testing while updating, if i uplug and replug the phone and place music on it, it will only keep the last folder, for instance i put nirvana nevermind on it, it will keep it, i then put a folder with two albums on it, say radiohead the bends and kid a, it will replace the last one , I am certain that space is not the issue, due to having placed less files on it the first time I restored the card agai)
Did you buy this card from ebay? A lot of counterfeit card on there. Cards that say they are 32gb but will only hold a quarter of that.

Try writing zeros with dd to the card... but be careful, dd will destroy anything you point it at, without hesitation. This is a typical dd command:
$dd if=/dev/zero bs=1M count=32000 of=/dev/somepartition
Where did you buy it? Like others have mentioned, it sounds like a counterfeit or broken card.
what is dd, and how can i tell if it is fake, every program ive used to check it goes through 29gigs of partition

DD is found in the terminal emulator on linux/unix systems. Be carefull, you can destroy everythign on a partition with it.
Also, you'll have to reformat afterwards ... the sdcard

Lots of the counterfeits are tampered with to report the "alleged" GB capacity. Its not until you try to transfer the files, that you run into problems and realize you were taken.
Again, where did you buy the card???
I apologize for not having answered your question, I bought it on eBay, I have been given a refund though. Where should I look for one at instead?
I got mine on amazon for like 55 bucks a few weeks ago been working great. It was a class 4 adata with a little blue usb card reader.
okay i bought a sandisk from a trusted store and again same thing, i am lost
What trusted store?
newegg class 4
Yup, that's about the must trusted store there is!
Any luck with lower capacity cards working? I'd say maybe its just a defective card. But its weird to have a string of bad luck like this. Is it possible the SD card tray on your phone is damaged?
Do you have an after market battery? Just curious...

Droid X SD Card not reading

Well i bought a Droid X yesterday for my dad for 60 bucks phone works great just the backlight is dead. The Problem i am having is my micro sd card does not read i have formatted it in fat32 and still a no go. I have no clue what i am doing wrong. The SD card does read in my Xoom and my bionic so i know its not the sd card. and the chips in my phone and tablet does not work in the droid x.
SD Card remount
I had a problem, and have fixed the same problem for many friends, where my SD card could not be read. My first recommended fix is:
Goto Settings > Storage > Unmount SD Card
Then simply remount the SD Card once the unmount has completed.
If this does not work let me know and we'll try something else.
well i just found out one of the pins for the sd card is shot so the phone is shot. Is there anyway i can save the phone or is it just trash now.
I really don't like TouchWiz at all, so, when the first ICS sources became available, I started porting AOSP to our device.
There are still some major and many minor bugs, but ROM seems to be stable and usable.
Please look for buglist below, so you can decide, do you need to flash it or not.
I'll try to fix those bugs as soon as possible, so please, don't ask when something will be fixed, I really don't know for what. I'd like wast more for Louis Vuitton Luggage
Description: This is clean and clear ICS (4.0.3) without any modifications. This is not CM, just AOSP. It may be used with tablet or with phone UI.
Take out the SD card and put it in another phone and when something pops up, you press ok then when its done, you put it back in your phone at it should work fine

If you've swapped around several microSD cards in your phone and none of them work, your phone is the problem. It more than likely has a dead card reader.
The only fix for this is to get a new phone.

[Q] HELP problems writing in micro SD S4

Hi my problem is, I was transferring some videos from my desktop to my S4 micro SD, it suddenly threw an writing error, a few seconds later I unplug my phone from the usb and then plug it again, I was able to copy the files.
Everything was okay until I restarted my phone, the videos were gone. And now doesn´t matter if I write or delete something from the SD card every time that I restart my phone or remove the SD it returns to what it was.
This is my 2nd 64GB micro SD having this problem the first one was with my Samsung Note 10 2014, but was exactly in the same way.
I need to know if it can be fixed and how or do I need a new SD card.
I can think of a couple of possible causes.
I'm wondering if you might have a fake microSD card. In other words, looks like 64GB, but is really only 32, or maybe 16 GB, or something else. Think where did you buy the card. If you bought on line especially, this could be the case. You can get software that will check it.
If the card really is 64GB, then maybe you can try reformatting it to see if that corrects the problem.

Memory cards corrupt because you copy large files at a time which cause fault in memory card internal circuits...Copy data at some intervals give it break dont try to fill 64gb at a time..

Strange external micro SD card problem with Moto X Pure 1575, please help!

Similar issue like in this post:
http://forum.xda-developers.com/moto-x-style/help/sd-card-problems-moto-x-pure-t3447789
But even worse. The external SD card suddenly vanishes from phone, now it only shows up shortly after phone re-starts, then the external SD card will disappear again. Don't know what's wrong. Then I put a new SD card, it happens like that after I used it for two days. The external SD card is used as portable storage.
When I tried to format the SD card when phone just started, it fails to do so, then it disappears.
I took both SD cards to Windows computer, they show up correctly and I can copy the files out from them. However, I cannot format them, they give out error: the exFAT card is writable protected. How a micro-SD card is locked for writing?
Tried to search online, but couldn't figure out how to solve the issue. It seems to me the phone has some issue with the card and changed the card somehow.
Can anyone help?
Thanks a lot!
I've had similar issues with SD cards that were going bad - weird, inconsistent behavior. Do you have another SD card you can test the phone with to confirm it isn't a rom or tray problem?
I once had a card that would work fine in TWRP, fine in a PC w/ adapter, but just show up as removed and added over and over again in a rom. Had another that could be read, but not written or formatted. It was full of music, but music players could only play about 5 seconds then they'd skip to the next song. Both of these cards failed in short order after starting this flaky behavior.
Based on my experience, I'd say recover your data and RMA if it is an option. Having microSD to supplement storage is convenient, but those things are cheap for a reason.

Had another that could be read, but not written or formatted. It was full of music, but music players could only play about 5 seconds then they'd skip to the next song. Both of these cards failed in short order after starting this flaky behavior.
Based on my experience, I'd say recover your data and RMA if it is an option. Having microSD to supplement storage is convenient, but those things are cheap for a reason.

Thanks, I've tried the second one(which works perfectly before I put in the phone) already, it ends up as the same bad state. I am afraid to brick the third SD card I throw into there...but I will try another one later.
I should have read more carefully. I wouldn't throw a third card at it if you've already tried two and had the same result.
Is this with the stock rom?

Yes, stock ROM, but I did root the phone.
I tried to contact Moto support and request a repair, funny enough it didn't go through because I don't have US address, which I did and put it right there!
For test, I put another small capacity card in the phone again to see what's going to happen...It might be the card, but two cards in a row...and they are different brand...Anyway, Lexar card will replace my card without trouble. But I still want to know if it's the phone's problem...Will see.

Be interesting to see if the small card behaves. If it is <32 gb it is probably fat32.
Some of the problems I described above started after letting an old phone format a high capacity card that started out as exfat to fat32. Some people say they do it and it is not a problem, but I tried formatting one 64 gb card from exfat to fat32 and broke it twice. Once using a phone and the second time using a laptop and gparted. Manufacturer did replace it both times. Left as exfat I'm still using the same card in my XT1575 several years later.

Just thought I would chime in and say since you unlocked your bootloader moto legally will not offer a repair unless you pay for it since you're warranty is now null and void.

Now I put 4GB card there, it works fine now, need to wait for a few days. My original cards are 64GB, both were formatted as exFAT, now both say being locked fro writing(what...the micro SD card is locked for writing...I want to know how...)

Yes, I heard of that, I just did a test drive there and it didn't go through...
