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...

Strange SD Card problem

I had a strange problem happen to my SD Card on my SG3. I have a Patriot 16GB class 10 card that I used on my EVO 4G for a almost 2 year without a problem. After when I got my new phone I clean all folders that I no longer needed except my pictures and some applications. Put the card in my SG3 and everything was OK. I was able to copy files take a pictures and everything seems to work the way it should. Last week I was on a trip and during the process to taking a picture I got a message that my card was removed and basically disappear. I reboot the phone and nothing happen. then a little bit later I saw another message that card was found and everything show up again. Then I check do I have all the pictures and most of them were there except on a last one was (when card disappear) basically it was look like that picture was taken a half way. So I delete that bad picture and continue. A day later it happen again but this time when card show up again instead a normal card I have that message in notification bar with a little sd card that it says Blank SD card. then if I pull down and click on it phone is asking me to format the card. I try to mount the card but got the same message Blank card or unsupported file system. Ok so I didn't have at that time my adapter to plug in to my laptop and wait until I got home to try to repair the card.
Here is what I got now and I'm not sure is phone damage the card or card slot on the phone is not good.
I use minitool under windows and GParted as well under linux. Both of them recognize my card as 60 GB Unallocated space (it is a 16GB). when I try to recreate or format both of them said successful but card is not show up. I have to plug it back and then it goes again as a 60GB unallocated space.
Does any one know how to format a 16GB card as FAT32? I mean the settings I have to use to put to get back again this card as a 16GB not as 60GB.
Sorry for the long explanation and thanks for you help in advance.
P.S. I' not rooted and on LG8 update.

Bro,did to trid any other sd?

Windows will format it just fine under Disk Management. The fact that its reading it as a 60GB... I'd bet on the card as bad. I have hours and hours trying to save thumb drives and SD cards. 97% of them had no hope. Sometimes the card reader can act up... but not likely, and the phone's kicking it out too. Try to stick with Kingston or SanDisk even if you have to pay a little more. Yes, Cards do go bad like that.

Thanks for the reply. It is look like that this card is going bad. It kind a surprise me since I didn't have any problems under my old phone. I will play a little bit more to try to repair it but....... looks like will be a lost a time.
Do you think that because it was a class 10 card causing a issue? I saw a couple treads but most of the SD card that people use are class 4.

I don't think the class would be an issue. How old is your card?

Probably 1.5 year. I got my EVO 4G back in sept. 2010 and bought the card a couple months later when rooted my phone.

Yeah, like root said, the class wasn't the issue. The different phone might have pissed it off but you really never know. I never liked Patriot myself, but then some people like them. Gotta back stuff up or have it auto upload somewhere.

last week suddenly received a message that the card was blank. did everything i could not to format it. finally gave in and tried formatting the sd card but couldn't. had to buy a new one. sounds like yours is going bad as well.

When I first got my SGS3 I used my old card from my OG Droid. I got an OTA update and my phone quit working (I got the "Unfortunately the process com.android.phone has stopped working" message). I took the phone back and they asked if I had ever had an SD card in it. I said "Yes, my old card from my Droid." I was told that this is a "known issue" with the SGS3 and that any SD card I used should be formatted in the phone itself. I'm not sure if this is the issue here, but it might be.

[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.

Known Good Sandisk Micro SD Card Not Being Recognized-Formatted FAT32/Compatible

I recently purchased a Note 4 (second hand of course) for my wife and myself. For some reason, my micro SD card will not be recognized. I plugged the Micro SD card into a reader on my computer and verified that it works. Then I reformatted it to FAT32 and tried it again in my Note 4 - no dice. I cleaned all of the terminals on the phone side and the SD card side with alcohol - still no dice.
I then plugged it into my wifes Note 4 and it recognized it just fine. I took my wifes known good SD card and put it in my Note 4 and it does not recognize it.
One last thing, I did a full factory reset the moment I purchased the phone. The SD card is a Sandisk 16 GB micro SD card. Either way it is proven to work in my wifes Note 4 so that shouldn't matter.
Has anyone else had this problem? Any fix out there? Or is this a true hardware problem? Please let me know and thanks for your help.

Sounds like a hardware problem with your phone. If you can return it and get a replacement from whoever you bought it from, that would be a good way to go. The phone should work flawlessly from the get go and you don't want to keep it if messed up right from the start.
The only other thing I can think of is that you take your SD card, install it into your wife's phone, let her phone format it, and try it in your phone again. Sometimes, for whatever reason, phones (and other devices) like SD cards formatted in the device rather than being done on a PC.

My note 4 is having issues with my Sandisk 64GB card also.. not sure why but after I play some music using PowerAmp for a while and then stop, it will no longer recognize the card until I reboot the phone! this process happens all over again each time I access it to play music.
So, sort of a similar situation.....

You might try pulling the card (unmount it first) and then reseating it. I know, it doesn't make sense since it only fails after playing music, but some have reported weird problems that were fixed simply by removing/reinstalling the card. You might want to clean the contacts before reinstalling it. You just never know!

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.

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.
