'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.

Note dismounts SD card for no reason...

HI all,
Yesterday the Note 2 decided it wanted to update itself.
After the update all appeared to be well, but i have noticed that the SD card decides to dismount itself randomly, for no reason. The only way to re-mount it is to restart the phone.
Any advice?

I have been experiencing similar problems recently. I have yet to find any help with the matter. One problem I have is that the Camera will not save imges to the SD card although the option is chosen in the settings. I have also had folders created on the SD card from a PC dissapear from the SD card shortly after disconnecting from the PC.
I downloaded an app called Media Scanner which helped with a few of the problems.
https://play.google.com/store/apps/details?id=com.clypher.mediascanner

It could be, unfortunately, your SD card itself. Other threads that had the same problem seemed to get solved by getting a new SD card. If you have another card, try that to see if it makes any difference.

had the same issue a while back. Happened out of the blue. One day I could save to external SD card and the next day I could not. Long story short I back up everything on the card and formatted it. Problem solved after that

Just to update this threat. The phone was acting a little strange, after each reboot it would recognise the SD card, then out blue it would ask to format it. I decided to plug it in to my SD reader and in the the computer. The computer would not acknoweldge the card itself so i decided to put it back in the phone.
Long and short of it is, the phone will not read the card either. If i insert a new SD in, it reads and i can save items to it. I am a little miffed as to why this has happened though.

Seems like a bunk SD card to me. This will happen time to time with low quality SD cards. Prob happened to all of us at one time. If the phone nor the card reader will recognize said card but will another this is a good sign the card is a goner. Sorry to be the bearer of bad news

Also got this problem often about two weeks ago. Don't know why exaxtly, aber after always removing SD when the dismounted-message show up seems to have solved the problem. Possibly there was some dirt in SD slot.

got the same problem
tried to format as FAT32 and exFAT.... still no go
anyone know how to fix that??
i am using sandisk 32GB class 10

there are a lot of fake SD cards around, low quality cards that get rebranded as quality brands. these are much more likely to fail
for that reason I only buy Sandisk, Lexar or Samsung cards, and only from reputable vendor (i.e. not ebay, and only from Amazon and not an amazon partner/merchant)

I use a SanDisk 64GB, bought it directly from Amazon.de and also got this problem.

I had a similar problem (of auto unmounting microSD card) with my prev. phone, the Galaxy S2, which was hard-bricked. I found it strange that photographs were missing from the microSD card (other than those taken with stock camera), practically the photos in the Whatsapp folders despite I had configured to save to external storage. I bought a 32GB microSD and so far, it has no issues with my N7100.
Previous microSD card was a Sandisk 16GB, new card is a Kingston 32GB.

[Q] Is my SD card slot damaged?

Hello everyone.
I have had this tablet for almost a month and so far, I have loved it. Last week, the micro sd card that I ordered arrived. It's a Toshiba Class 10, 32 Gb. I inserted it, and nothing happened... then I tried again and a message appeared, telling me that the card was being prepared.
After a while, another message told me that the card had been "unexpectedly removed". I tried it on my PC and it worked, but started looking out for a solution and found out a program to format it on these forums. I used it to format the card with FAT and tried again.
This time, the card worked for a couple of hours, then the tablet told me that it had been unexpectedly removed again.
I took it out, used my pc to reformat it, put some files and tried it on an Android based media center. It worked and still works.
So, I went to the store and bought several other cards, and so far, either they work for a couple hours before getting the "unexpectedly removed" error... or they don't work at all.
Here's the list of all the cards I have tried:
SanDisk Class 4, 16Gb
Kingston Class 4, 32Gb

I know, the SD Slot is unusually deep and it takes some time to get the card into. However, I have inserted it until it "clicks" into place, but nothing works.

[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.

HTC 10 damaged micro SD card

HTC 10 damaged my micro SD card. Did happen to anyone else?
I listened music form my phone on my way to work in the morning and then, on way back home firstly music didn't play, so I found that card is not recognized by the system even after restart. I have checked it later on two computers with 2 different adapters and no appliance can recognize the card. Branded 64 GB Lexar fast card. HTC wasn't restarted or so, wasn't even hot I kept in whole day in the pocket. I'm not sure what to do, I mean don't want to lose another memory card which I probably buy.
And maybe, by any chance, someone have any idea how to check memory card whether is completely dead?

Did it ever occur to you the card could have had a hardware failure?

It's more likely a short life span micro sd card, and this kind of suck always happen once a while.
Don't blame your phone unless other one or two micro sd cards also die in the first two weeks.

Hi, The reason I'm asking is to avoid the risk in the future. If it happens to anybody else I will rather buy some cheaper card.
That memory card was bought for GoPro so I use it for many other apliances without any problem and suddenly it broke with HTC 10. At least I noted it here for statistics.

...and if it had broken in one of your "many other appliances" it wouldn't have been broken by your HTC 10.
Cards fail. Cheap cards fail often.
Lesson, buy more than one card and don't recycle them from device to deice.
Another lesson, don't ever buy cheap cards.

lexar isn't usually horrible, but yeah sd cards fail. On the notes of sd cards dying my t3i must have killed my sandisk ultra 2, it couldn't have been the card that died.

The HTC 10 does appear to be finicky with microSD cards. My 128GB Sandisk that worked totally fine on a Galaxy S5 kept giving me problems on the HTC 10. I wonder if the phone is stressing the cards too much somehow (for instance if it is scanning the card too often for media files and you happen to have tons of media content on the card like in my case).

Thank guys for the reply,
I never broke before any memory card and that one was not cheap. Happily I can buy now double capacity and double speed for half of the price which I spend for the last one. I'm planning to buy Lexar 128GB. That card did work perfectly but only few days.

I'm having issues with my card as well. I purchased the SanDisk Ultra 200GB Micro SD from amazon. I put it straight into the phone and ran diagnostics on it to confirm it was a true SanDisk card and its read/write speeds which were in line with manufacturer's specs (88 read/ 14 write). Within the day it was having issues pulling images off the card. All the images saved directly to the card had a grey area or "box" over some portion of the photo that would correct after a few seconds leaving the full picture to view. The images could be sent with no problem but eventually they seemed to become corrupted. I figured it was the slow write speed causing the issue so I replaced it with a new Samsung ProPlus 128GB card (95 read/ 90 write) and the issue still persists. Not sure if anyone else is seeing anything similar.

if your looking for a new one, this one is great. very fast speeds 90mb write 95mb read. bit on the spendy side so hopefuly it was just the card failing and not the HTC 10 eating them
I haven't had any issues with 1000s of files on mine so far, crossing fingers

Same here, Kingston 128 GB micro SD worked fine on my s7 edge. Inserted the same card in my HTC 10 and it was readable for the first hour, after that the card was not recognised by the device. The card wasn't even recognised by my Mac and PC. I'm glad I had my photos backed up on google photos.

My 64gb kingston kicked the bucket in my HTC 10. Last weekend I woke my phone up and it said sd card unexpectedly removed. Card was not readable in any other device.
Got a Sandisk as a replacement as never had an issue with their cards in the past. The kingston only lasted 4 weeks, but I'm putting it down to just a faulty card.
If the sandisk dies too, then I'll be a bit concerned it could be the phone...

Im Using Lexar Pro SDCARD 128gb and havent had issues using it. The card was also formatted as adaptive.

So, there is two of us. There is one only connection - 64gb.
Where is Sherlock?

You're made me worry. I use SanDisk 200 Gb, it's kinda expensive one.

Worry for what?
I don't have any issues with my HTC10, but I broke a 64gb Sandsik in my Sony X10i, phone just got hot. Shut down, Card didn't work anymore. And another one SanDisk 128gb was in my Sony Z2 when I replaced the back plate somehow the MicroSD got broken.
The 64gb Card had a Lifetime Warranty and the 128gb a 10 year. Not sure how long my 200gb card is now. Think they reduced it to 3years or 5.
But yeah, went to their Homepage, registered the cards. Requested replacement, they sent someone here to pick them up, 5-9days later I got the new Cards via Mail
So yeah, always back Up your important stuff somewhere else and who cares if they fail. It's annoying Yes, but **** happens.

SD cards can fail in ANY device. I wouldn't go as far as saying it failed because of the device. Quality of the cards is what really dictates how soon failing can occur. A knockoff SanDisk failed in a few months while the real one has lasted years for me. I highly recommend SanDisk and Samsung SD cards because I have had no issues with their original products.
EBay and some Amazon sellers have tendencies to sell fake cards so beware.

I woke up this morning and my HTC 10 says that the micro card couldn't be recognized. Crap. Did a search and found this thread. The card is a Lexar 64gb card. I went to Walmart this afternoon and got a Samsung 128gb card. Hoping this card will last my long tern stress test. Ha!

been using this without any problem 128gb and prior to this i tried samsung evo + 128 and that worked fine....
but as the OP stated it is true that many users using diferent sd cards has been facing issues with htc 10.....
some has issues on some firmware, some on custom kernels, some on different formats so its wise to say that there is something beyond a faulty sd card itself.
in all the custom rom threads you could see sd card issues highlighted at one point or other by mutliple users including devs

I have the same issue, and now i remember this is the second one in my htc 10, first one a pny 128gb worked well for more than one year in my previos s5 and after a month in my htc it failed, i blame the sd card that day and decide to buy an 128gb lexar and today after 5 months it failed, or i have a very bad luck now or my htc is damaging my sd cards.
