SD card not being read

Okay, I've not really payed much attention to my Play at all, I've probably picked it up once this week to realize the sd card was not being read, after formatting it and trying over 3 sd cards I come to believe something is up with the phone itself, My S3 also cannot read the sd card, any suggestions, I think its an issue with the phone itself, I've flashed back to gingerbread and still nothing.

Format it with a computer.
This worked for me...
Sorry for my bad English. It's not my native language.

If the microSD is not being read, put it in a BlackBerry. The Blackberry should ask you to format the card so it will be usable. For some reason, this worked for me and now my microSD is working fine. I already added a new UHS-1 card by Sandisk to my cart before I tried to fix it. It saved me some money .

odd sd card problem, help?

i have a sandisk 2gb sd card and another 8gb sandisk card, but one of my friends scrapped a 16gb internal sd card out of an htc surround7. the 2gb and 8gb cards work perfectly fine in my epic 4g touch running blazer rom and either agats kernel or the kuban kernel, but the 16gb card wont mount in the phone, and if i pull the card out, it causes the phone to reboot. ive done the same thing on my friends evo 3d and my brothers galaxy s3, and had the same problem. it also wont mount on windows 7, 8 or linux mint. any ideas on the problem/ how to get the card to work?

i had the same problem with an 8gb card even when i put it inito a card reader via usb the card actually started to heat up. i sugges you to throw it out and get a new one its not worth messing with it

it didnt heat up, theres no problem with the contacts or anything, i think the filesystem on it is corrupted, and that could be fixed if there was a way to mount it

Have you tried reformatting the card? either NTFS or FAT32 partitions. try it via a PC. not the phone

it wont mount to my pc in windows 7,8 or linux mint either through the phone or with an sd adapter. i need to find a way to reformat it

Sounds like a bad card

Any way to fix it though? Anyone I can ask? Or is it just a waste of silicon and copper at this point?
Sent from my SPH-D710 using xda app-developers app

I don't think these can be fixed. They are really cheap to replace though. I think my sandisk 16gb was about $10 from eBay.

Eh no biggie. It was free anyway. What's a good price for a class 10 32gb? I saw a sandisk in target for $44 which seems steep, and RadioShack had a class for $22
Sent from my SPH-D710 using xda app-developers app

The current rate seems to be about $1 per GB. You can probably pick one up on eBay for less though usually lots of auctions on these. My sandisk is a class 4 but speeds are good for my use
Also
Here is one at staples on sale now http://m.staples.com/Polaroid-32GB-microSD-microSDHC-Class-10-Flash-Memory-Card/product_730752
Not sure about that brand but if the store is convenient you can always return.

[Q] Anyone have problems with 64GB SanDisk SDXC card?

I have a Bell Note 2 and I recently bought the 64GB SanDisk Ultra microSDXC UHS-I card. Since using it, I noticed that (when installed) the Device Status of the phone changes to Modified and I can't check/download Android updates from Samsung. Also, the Samsung Video Hub app won't let me use external storage to save movies (which I could do using my old 32GB PNY card). The card seems to read/write okay though.
I contacted Samsung by email, the reply was laughable (solution was for a different issue on a different phone). I also contacted SanDisk and they suggested reformatting to FAT32 using a utility from www.sdcard.org. I haven't tried this yet but I know that FAT32 will reduce file sizes to 4GB. I don't know if it will have an effect on the read/write speeds of the card.
Just wondering if anyone else using this card was experiencing the same issues. If you haven't checked, maybe you might want to.

I miss the build quality, sleekness, and how quick the battery would charge/how slow it would drain.

Well, I tried to do what the SanDisk guy told me but the formatting utility that he mentioned doesn't have the option to change file formats. Started out as exFat, still exFat. Some of you have mentioned using other formatting/partitioning utilities - the folks at www.sdcard.org say the following:
"The SD Formatter was created specifically for memory cards using the SD/SDHC/SDXC standards. It is strongly recommended to use the SD Formatter instead of formatting utilities provided with operating systems that format various types of storage media. Using generic formatting utilities may result in less than optimal performance for your memory cards.
The SD/SDHC/SDXC memory cards have a "Protected Area" on the card for the SD standard's security function. The SD Formatter does not format the "Protected Area". Please use appropriate application software or SD-compatible device that provides SD security function to format the "Protected Area" in the memory card."
So there you go.

I am using the card with the t-Mobile version and it working fine.

Works without any problems in mine.

The weird thing is that it starts out okay and only shows up after I've reloaded all my apps. Even then, I can still read and write to the card. I just can't get updates because it says that my phone is modified. I can't see how an app would cause it. There are no side-loaded apps. And it doesn't happen with my 32GB card.

Just a quick update for anyone who might be wondering....
After making this thread, I went to my local BestBuy and bought another SanDisk microSDXC that was exactly the same as the one I had. I put the same files on the card and the phone did exactly the same thing. I did discover however that the problem shows up when I reboot the phone with the card installed but doesn't show up (at least not right away) when I unmount/hotswap/remount the card with the phone left on.
Then I took the card to the BellAliant store where I bought the phone and had them try the card in a brand new phone. Same problem on the new phone.
Nothing funky on the card, just my songs (transferred using DoubleTwist AirSync) and my photos (transferred via PC). This card hasn't been reformatted and my phone hasn't been rooted.
So I don't know what's going on, if its only a problem with Galaxy Note 2's that are being sold in this area. I can't believe that no one else is having this issue.
Anyway, I put in a support ticket with Samsung (again), not expecting anything new. The Samsung tech that I spoke with did say that only TWO (I think) 64GB microSDXC cards were tested and approved for the Note 2 and that the SanDisk was one of them. Also, the girl at the BellAliant store said that they were told that the phone only worked with a TOTAL of 64GB (internal + external) but I KNOW she was wrong about that. Just some of the things you hear when trying to troubleshoot something that no one seems to have an answer for....

iMHO you really should format it fat32 and retest.
-- other suggestions for tools --
Might search for mini partition tool or gparted live cd. I've used the gparted live cd to partition my 64gb sandisk previously for dual booting my og atrix.
-- I'm sure there are better suggestions on tools, but I strongly suggest converting it to fat32 before further testing / actions.

The Note II ONLY supports FAT32
When I got my new 64GB SanDisk card I powered off the phone. Pulled the back cover and replaced my 32Gb with the new 64GB micro SD card right out of the packaging and then replaced the cover and powered it up. Phone recognized it and accepted file transfers to it without issue. No problems to date and I have been using it for 3 weeks without issue.

ExFAT works fine with my note 2 on perseus. Doesn't play well with note2core though

If the Note II only supports fat32, then someone needs to tell my note because it's working fine with my card on exfat. stock kernel and all.

I too have bell note 2 with 64gb sandisk and everything is fine. I jusy put the card in the phone and formated with phone. Its exfat btw.
I suggest u to format the card with phone so it can format with the appropriate fike system.

See, that's the strange thing. The card DOES "work" - it formats fine and I can transfer files to and from it. The ONLY problem is that, when I put my files on it, the status of my phone changes to "modified". Then, when I go to updates, it won't even try to connect to the servers, just tells me that my phone is modified and that updates are not available. As I mentioned above, I've duplicated the problem with two identical cards and in two different phones (one of which was in-store, brand new).
I realize that I can just take the card out of the phone when I know an Android update is available to download, I just don't always know when updates are available. In either case, doesn't seem like it should act that way. And I didn't want to force-format the card to FAT32 with a 3rd party format utility because that would destroy the "protected partition" on the card and void the warranty (those 64GB cards are expensive).
I understand that I might just have to live with this, it's just odd that no one else is experiencing it. Think I'm going to let this thread die. Folks on XDA tend to not like re-reading the same thing over and over. Thanks to all who replied.

Why do you think formating an sd card with fat32 would void the warranty? Never heard such thing before. You can format any file system you want.

UPDATE (see post#30):SanDisk Ultra 32GB kiss of death? (

For the past 4-5 months, I've been seeing quite a few posts regarding issues with the SanDisk Ultra 32 GB microSDHC Class 10 UHS-1 Memory Card 30MB/s with Adapter SDSDQUA-032G-U46. I bought one back in November 2012... been running it hard for 6 months without incident.. so figured I was one of the lucky SanDisk recipients.... until today! Starting today, every time I wake the phone get the "sdcard mount" message. So loaded "SD Card Monitor" from the Market (screenshot attached) and found that during deep-sleep, it unmounts/mounts/removed/bad-removal/ejects constantly (example: phone slept from 10:04am to 10:22am)...but during wake state, no issues. So I suspect I'm about to experience the SanDisk 32GB Ultra kiss of death any day now. Backed up ExtSD to computer, but now the search for a proper extSD replacement. Any recommendations? Leaning towards Samsung 32GB or 64GB...
UPDATE: SEE POST # 30

Yea I just bought mine about a month and a half go. One month in of using it, my card corrupted and I ended up having to reset it. Lost everything! Lucky I put anything of importance on my cloud before it finally died on me. :banghead:

Are you having issues with dropped calls too? I was thinking I was alone, and maybe it was a bad module? I got my phone 2nd hand, and that's my next step to order a new sdcard/sim card module and try to replace it. Data works fine and never cuts out, phone calls last maybe 30 seconds, and it's killed 2sdcards already. ..

FAT32... not a single problem for 5 months until today... and I r/w the crap out of my extsd cards daily... we'll see what happens.. still works, just getting these warning messages.

Really like that Samsung SD card idea.
Back to Amazon. ...g

I purchased one of these from Amazon last week. Works like a charm, albeit only when formatted as FAT32.
It is roughly twice as fast doing read/writes than my previous Samsung 32GB card.

My Sandisk stoped working also, so I bought the samsung 32gb and it's starting to do the same thing again. I just think there is something wrong with samsung phones in general.

I haven't had any issues with my sd card or phone. But a buddy of mine has burned up 3 pny cards and one sandisk. Although it's an s3. Sounds like a phone issue. I told him to call a warranty claim.

[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.
