Storage Card no longer recognised

I've have an XDA Stellar for 17 months, with the same Sandisk 8GB Micro SDHC storage card all along. Some months ago, it suddenly stopped recognising the card, but my PC could read the card fine. I couldn't face another hard reset, soft resets did nothing nor did blowing air from a can into the slot.
A month later, I changed batteries (which wasn't unusual; I have two official batteries for when I can't get to a charge), and suddenly the card was recognised although I had to reload most of my programmes, but at least I could access them and most of my files again. I was too superstitious to change batteries again although that made little sense to me.
Last week, the card 'disappeared' again and nothing (even a battery change) will fix it. The phone is nearly useless to me without all my programmes on that card. Does anyone have any suggestions for a solution? I've found nothing that works and it's driving me mad. Thank you for any possible help.

hi
first of all i am not a professional but what i would do in your case is:
put the storage card in another phone
sync with pc/save files in a folder in pc like sd backup
buy a new card and put it in your phone you are using now
copy the items in your new card
i dont know if it helps try at your own risk (there isnt much risk)

No Storage Card recognised now
Finalforce111, thank you for your response. But I forgot to add that I had tried other cards when this happened and it won't recognise any, not even eg the one that came with Copilot. So no storage cards are recognised, although they were before.
But thank you very much for your suggestion; it is much appreciated.

I would like to say that your Card Interface is somehow broken,i´ve your lucky,its just a cold soldering place..

Fried SD card

Unplugged my Desire from the charger yesterday to discover the SD card had failed totally. Rebooting failed to recognise it and once the screen switched itself off I couldn't get it back on. With SD card removed the phone seems fine but the card is not recognised in any reader now and can't even be reformatted. Did the card just die (it got very hot) or has anyone else had this experience?

A possible SD card failure not caused by the phone or reader. IVe seen this happen and be reported before with certain brands. You should return the SD for a replacement (assuming you have tried all the normal ways to try and read it)

I had my 32GB class 2 do the same thing, I whipped it out and put it into a USB reader then reformatted. I fully believe that its down to not 'ejecting' the card first before unplugging it since I selected the device (card) to be read as a drive.
Just be careful dude, its a royal pain restoring everything, keep a regular backup of your card if you can spare the GB. its's real time saver.
I was a bit worred too about the heat of the device effecting the micro SD card, but from what I read its still well within the safe requirements of the card even at 40C.
most cards come with 2 years+ warrantly especially Sandisk so check that out if you've well and truely screwed the card up (it happens, sadly.)

Had this same problem yesterday with an 8gb card. Just wont but with the card in the phone. So far it has done it twice in a week , one 4gb , one 8gb, both times while I've been using HTC's music application. Don't know if its just a coincidence or not...
Do you use a task killer? Wondered if I'm shutting something I shouldn't be.
Was it a goldcard?

Thanks for the responses. No task killer active and cannot reformat the card because no reader will recognise it. Guess it has gone to the great card graveyard in the sky

May it rest in peace my friend...I sympathise and am sorry for your loss...
Before purchasing a new one make sure that it's not something with the phone.Can you live a few days with the spare 4GB card that came with the phone?Fill it and use that for a few days and see if something similar happens again.Except for if you've been using that already...

could creating a ext cache partition have anything to do with it ?
i had the same problem but managed to get most my data back first time....stupidly i formatted it and carried on using it. couple of days it died compeltly !
learnt my lesson and make sure i backup every few days- pain yes but it's the same with any data if you don't want to lose it back it up !

...premature death announcement there. After a couple of days rest in a darkened jacket pocket, the card is suddenly visible to my laptop again! Clearly on its last legs as several files corrupted and it refuses to reformat but at least I rescued most of the data.
As usual the only backup you ever need is the one you didn't do!

Try formatting with a digital camera...
I had a similar problem with a corrupt SD card in my old phone. Computer wouldn't read it, but managed to format it using a digital camera after which it worked again (and still is).
Might be worth a try before consigning it to the bin...

[q] keep losing microsd

I have a Tilt 2, with an 8GB class4 micro-sd card. I used to have a class 2 4GB card. I'm currently running with the latest version of Nrgy's ROM, before that I was running the HTC updated rom and before that, the stock rom. From the first time I got this unit till now, I've had a problem where it will suddenly and for no reason, "forget" that the micro-sd card is there. Programs won't launch, because I install them all on the card, and I have to soft-reset the unit before it will recognize it again.
Is there any way to fix this permanently???

Is it after connecting the phone to your PC via USB, or completely spontaneous?
What brand of SD cards, and where did you buy them?

It does frequently happen after I connect the phone to my pc at work, but not always. The original card was a Kingston, the new card is by Transcend. Don't remember where I bought the first one, the one that's in there now was bought from Newegg.com. I also noticed that a soft-reset doesn't always bring it back...I have to eject the card, put it back in and then soft-reset the unit before it recognizes it.

You either have a bad SD card, or a bad SD slot. The former is far more likely, however. Try this out with another card. If it works with another card, then just see if you can exchange the card. If it gives you issues with another card, set everything to stock and do a warranty exchange.

Kingston in particular is plagued with counterfeit knockoffs, and its hard to guarantee a genuine one if you buy from ebay, or other places except the most reputable sources (such as Newegg). The counterfeit ones seem to have a variety of strange behaviours on the TP2, along with not having the advertised storage capacity.
Now, this doesn't explain your issue with the Transcend card from Newegg. I'm thinking a bad card, same as suggested above. You can also try a full format of the card, and starting from scratch.

[Q] SD Card Issue (Yes, still not solved)

For the longest time, I have been unable to use my 128GB Sandisk MicroSD card properly with my GN4. I have tried SD card fixes, foldermount, and messed with the platform.xml file as well. What I used to do back in the days of ICS/Pre KitKat 4.4.4 was take the SD card and plug it into my computer (via SD card adapter) and transfer the files I needed directly since it takes a while longer if I connected the phone to the computer. I can still transfer files to the microSD card if I plug it in, but they are not able to be read. This is starting to piss me off as I have a lot of music that I would like to store on the card. Anyone have anything else they can suggest?
I used foldermount last week - Some of the music files work properly, while some don't play and I get the message "unable to play this file."
I bought this card brand new and I'm hoping it's not "a bad card"

I also use a 128gb Sandisk Card, the "ultra" I believe. I never had a problem with it, I just came from the Note 3 and put it in the Note 4 with no issues. Is yours the "Ultra" also?

Maybe a bad card. I got 3 fake ones on eBay before I got a real one. I flipped out on the sellers and reported them. Each time I got a bad one I spent hrs copying data over to the 128. I would copy over around 20 gb, and another 20 and so on. When I went to look at the files that I had first put on there they would be gone. There are programs u can download for free. Just Google how to tell if sd card is fake. A fake card is really a 2/4/8/16/32 card changed to look and act like a 128 and once it hits it's limit that u don't know what that is, the earlier data that was put on the card, disappears.
Here is a link for a program I used:
http://forum.xda-developers.com/showthread.php?t=730285
This happened to me back in Oct/Nov when note 4 was launched. I ended up paying $120 on eBay for SanDisk's highest r/w 128 gb card.
The first seller claimed he didn't know they were fake and promised to stop selling them if I retracted my bad feedback as it was the only bad feedback he had ever received. Once I saw they were removed from his selling list I retracted the feedback. The second and third sellers I was not nice to, did not even have to send them back the pos card. My response was something like refund my ****ing money now for selling me this fake ****ing sd card. Ten minutes later both had gave me my money back. Assholes. After I got a good one I had contacted the first seller again and explained how much trouble I had and the scam artists there are on eBay. I feel that he was genuinely sorry and had no idea. He also stopped doing business with who he was getting the fake cards.
This good card has been great, note 4 32 gb internal, 128 external, both full, zero problems.

Plug it into your computer and check if it's formatted correctly (fat32 vs NTFS). That might solve the problem. Don't quote me, but I think it needs fat32.

Yes it does need to be fat 32.
Also if is fake, u might format it, move data, insert in phone, and it says it's not readable and needs to be formatted.

Yes mine is the ultra version as well (in red letters on the micro sd card)

the two options are exFAT and NTFS. I formatted on exFAT and it seemed to be working just fine until today.
So I use my sd card as direct storage for when pictures are taken. I was at dinner today and took pictures of the food we ate. All of a sudden when I go to the Gallery, I see a black and grey image with an exclamation point for the pictures taken at dinner with the exception of one. I am wondering whether Samsung/Google is releasing updates that put the phone back into the main issue of not being able to R/W to the external sd card? I don't know what else could be the reason. I also tested the card to make sure it wasn't fake. SO DAMN FRUSTRATING!

Shouldn't have to format it. Already exfat when it comes. If it's real, contact sandisk with pictures of the card and it's serial number and a copy of the receipt. They will replace it.

Micro SD Card corrupted? [write protected]

Hi folks of XDA! I am in a bit of a pickle right now with my micro SD card that I purchased a while back from ADATA.
Long story short, I purchased a 64GB micro SD card from ADATA due to my needs of a little more storage than what this phone offered. I ended up using the micro SD card as adoptable storage as I wanted to be able to use both my internal and micro SD card for 'everything'. It worked great until the night before I was suppose to go on a cruise: music wasn't being downloaded as it said it had insufficient storage space, and I couldn't take pictures with the camera app because it couldn't find the storage. I got frustrated as it was showing I had over half of the storage available on my SD card and I just did not have time to meddle with this problem; it was late at night and I simply needed my phone for taking pictures & videos & music.
I ended up doing a 'no no' and ripped the micro SD card out of my HTC One M9 without formatting or anything (literally just popped it out of my phone), restarted the phone, and surprisingly nothing was corrupted; everything on my phone was still working. But not surprisingly, the micro SD card got a little weird where when I put it back into my phone, it did not recognize it and my phone wanted me to format the micro SD card. Fair enough. I did that and it said it could not be formatted ("Volume partition disk: 179,32 public' failed..."). Fair enough.
I went onto my Windows 10 PC, slotted my micro SD card into the adapter that it came with, slid the little notch away from the 'lock' on the adapter, and my computer says it needs formatting. I try formatting it but all it keeps saying is that it's 'write protected'.
I slid the notch on the adapter to the lock, and away, as well as kept it in the middle; nothing helped, it kept saying it was write protected no matter which part it was on.
I tried using scotch tape to cover it as some people on the internet found it to work when their slid mechanism broke. Still did not work.
Tried using another adapter, and it still said it's write protected.
Resorted to using the DiskPart technique via CMD; everything shows up, the micro SD card status is online and disk 1, 58GB, 0 free space.
Tried going further into the steps (i.e. "attribute disk clear readonly" & another way, "select partition"), and it says it could not be recognized due to fatal error of hardware.
Would anyone happen to be in this situation before and was able to get their micro SD card fixed or knows a fix for me? I'll be happy to give you more in-depth detail if needed. Thank you!

Did you figure it out? I've had similar issue. I had to insert and remove multiple times until my PC recognized it... I think when I booked to Linux it worked though.

That sounds to me like the SD card is toast. I think it's built into the cards themselves that if the controller is going, it goes into read-only mode so that you can get your data off of it. I had an SD card bite it the first day I owned it a few years ago in a camera. I would use either a Linux VirtualBox or Linux Live Disc to copy your data to your computer and buy a new card.

Unfortunately I still haven't figured out how to fix my micro SD card; it's just sitting on my desk collecting dust and sadness. I'll update this thread if I happen to fix it!
Also, "booked to Linux"?

Fortunately everything important like photos were already backed up into the cloud and my micro SD card has life time warranty so I guess I'll have to end up using it. AHHH cost of shipping & time from my impatience with removing the micro SD card. My hunch is that the encryption that occurred when I used the micro SD card as an adoptable storage may have ultimately screwed it up... ://
If anyone have any clues to how to fix the problem or would like me to try things with it, feel free to post a reply

I've tried using Linux but it's not working.
I'm having Two SD-cards collecting the dust as yours .
Please reply if you find any solution for revering those adoptable sd-cards back to working.
Thank U....

The nature of solid state memory is that any errors causes a complete failure. You will never recover the sd card. Return it to the manufacturer for a replacement.

Hey! Sorry for the late reply (school exams) but mine is still collecting dust and will be probably forever. For the price that I've paid (~$30), it's not worth to replace and it's better if I just purchased a new SD card. Time + effort to get a new one is far too great for me to care about getting a replacement.

But even after sdcard replacement if you use same rom in your device then the new one is also going be damaged
My device has only customs roms of android 6.0 so there still bug in them if i get new sdcard i cannot use latest version in my device So i have to search for solution to unlock these sdcards

Oh I see. Fortunately for me right now, I am not using a custom ROM. I've been sticking to stock HTC and will proceed to do so until HTC stops giving out updates. I am not quite sure what you could do except try to manage with the 32GB like me by deleting all unnecessary apps, putting all your photos and videos into Google photo, and caching music that you find yourself listening to the most these days. So far it has been working well for me to the point where I don't find it necessary to have an SD card anymore! Perhaps it's a different case for you.
