'Dead' 16GB SD card?

Hi all,
Happily listening to music with Core Player on the TP2 I received last Saturday and the phone lit up with a message from Core Player that it wanted to update my media library, following the removal of the SD Card.
Suffice to say, I was confused: no chance with the SD card hidden under the battery cover that it could have been loose and fallen out but checking through File Manager on the phone, the SD card can't be seen at all.
Put said card into an adapter and then card reader on my PC; it comes up to suggest there is no card inserted: put the same card via adapter into my digital camera and the camera refuses to even turn on with the card in.
It's a duff card I'm sure - bit peeved since it wasn't that old but meh: don't trust all eBay sellers selling 'genuine' SanDisk products I guess - however, whilst I await the arrival of a new one, could it be my TP2 that has damaged the card in some way? Has anyone else noted problems with the TP2 and higher capacity SD cards?

FlashROM based cards only have a certain number of writes. Same goes for SSDs. They should have a way to track number of writes to cards. I've had official Sandisk cards go bad on me within the first year too. Don't forget that static shocks from your clothes can actually damage the card. Also don't forget that your phone can corrupt your data if it's in the middle of a read/write op and you remove the card.

Thanks for your thoughts mate: it wasn't removed from the phone and the phone only had CorePlayer running on it at the time - so I don't think it was anything I'd done
I think I got duped by someone on eBay selling a 'Geninue' Sandisk card that perhaps wasn't - I've read here than Danetec are also quite good so I've ordered one of them directly: fingers crossed I have more luck with my second one!
I was more concerned with it possibly being my phone - I read a month or so back on the Diamond2 forum that 16GB cards didn't work so well with that phone and wondered if any forumites here had noted any issues with the TP2 and certain SD cards, thats all...

it happened to me last weekend, due to an automatic update of go news touch which went wrong.
no way to see or format the card on the ppc or my netbook. I had to go back home, put it into a usb adaptor, and finally format it with mu desktop pc. my little cer netbook couldn't detect it, and locked up each time I tried formatting it, even from cmd console. but on desktop with adaptor it went just fine.
hope you'll be able to resolve - my sandisk card was 20 days old, 65€ worth, and having it toasted isn't something I would wish to anyone

In this case, it's not even recognised - via a card reader, active sync or inside another device: this one I think is lost Meh, it's only money

Hi All
Paulplex, don't feel you are alone, this happened to me too with a genuine Sandisk 16gb card. It worked last thing at night, went to access it in the morning and it was dead - just 3 months old with no issues at all up to that point.
The solution was replace it as it would not recognise via a reader in the pc either - completely useless....
The cause? Who knows, i do suspect the TP 2 though as i had no issue with it on my old Dopod 838 pro for the first 2 months since new.

[Q] phone will not recognize sd card at all

Okay so I dropped my evo on memorial day. The back cover came off and out came the battery, sd card was intact and still locked into phone. I put the battery back in, and when the phone turned on it kept saying sd card not mounted or found whatever. I've tried mounting it through recovery, it can't find it. I can't take pictures nor see my gallery. I bought a sdcard adapter. It's a sandisk sdhc adapter but my computer will not recognize it when I insert it. It reads the sandisk microsd card just fine but not the samsung
Im running cm7 and everything was working flawlessly until I dropped it.
Any ideas?

I had the same problem with my 32gig SD. It turns out my card just broken from the fall. After trying to format it and mount it a million times I gave up and sent it back. New card hasn't given me one problem. Hope it helps.
sent from my lazy a$$ at "work"

i just dont see how it can be broken considering it looks like it did the first day I had it lol

The outside may look fine but the internals are microscopic and I know even some of the best card out are only rated to take a 10 foot drop. Maybe you could borrow a friends sd card to test it out. Thats how I found out it was my sd. I formatted and put my factory 8 gig back in and it worked just fine.

I just hooked it up to my computer. It recognizes the phone but does not allow it to become a storage device because of drivers that are not installed

ok so I realized something. The computer I am currently using is my new comp which it is not the comp that i rooted my phone with. when i hook up my phone there is a driver that will not install and windows 7 cant fix it. Could it be that I need to re download the driver in order for it to see my sd card on my phone?

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.

I do have all the pictures auto uploaded to my DropBox account and all apps I backup on my PC. I just wondering if the card slot of the phone is bad. I have a new 4GB class 4 card. I will put in to the phone, format and try to see if it happen again.

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.

also try this thread as it has helped many

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.

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.
