SD card fried.

I had asked for some insigh on the issue of my external sd card unexpectedly ejecting itself (not physically) , and someone told me the fix was to format it on the computer first, then put it back in thw phone and format it. The problem got even worse and then deleted all my data, and now wont even recognize that the card is even inserted. Am i screwed? Im hearing other people are having this problem as well. Whats the deal!?

Will the sd card read on the computer?
Also when you format your card.... That is basically deleting your data....

Funny you mention that about your sd card, my lexar 32gb card got fried. Lost all data too. I now have the 64gb SanDisk microsd card so hopefully it lasts longer than the year that I got out of the lexar

Having the same issue as well. I bought a sandisk class 10 sd card 32gb when I got my note a month ago. I started to notice the same messages about my card once I updated out of the lk1. My card is draining my battery life as well. So right now I'm experimenting with a blank 8gb sd card in my phone. It's only been a few hours but I havent had any kind of sd card messages. I think the sd card is the problem...why...idk

Has this happened to anybody whom switched their external memory for the internal? I ask because I would like to do that, but if the SD card fails will it perma-brick the phone?

my 32g SD card (forgot which brand) fried one month after i got my note 2. it was fine the night before, then the next morning a message on my phone said something about it cant read the SD card. my computer couldnt even read the card. lost everything from pictures and videos, man o man

I've gone through two micro sd's, both Sandisk, a 32GB and a 64GB.
The 32GB card was Fat32, the 64GB card was ExFAT. They both worked okay for a while, then I noticed the Android media scanner running too often, then I started getting the "unexpected removal" messages. In both cases once the "unexpected removal" messages started the battery life becomes unacceptable.
I was storing about 26GB of ALAC music files, using iSyncr->iTunes and Rocket Player.
I tried formatting on the phone and starting over and formatting on the computer and starting over, and low-level formatting the 32GB card. It would work for a little while and then the behavior would start again.
I'm not using any card at all now. I may try again with something other than a Sandisk to see if it makes a difference, but I don't feel like gambling the cost of a new card for a while.
[ Edit ] If it matters, my Note2 is not rooted, and running the stock ROM with all updates.

I had the same thing happen to me this week with a Class 10 Sandisk 64GB Ultra. I had had no errors since purchased at the time I got my Note 2 (release day). Suddenly the card was unreadable mid day on the Note 2. It couldn't be read by PC either. I did reformat on the PC and was able to recover some of the data with the Sandisk recover tool purchased from the Sandisk website. After reformatting I did try to use it again in the Note 2 but it failed nearly immediately. I am in the process of replacing it under warranty and am now using the 16G Sandisk card that I had been using in my Evo 4g
I am using the leaked stock LK8 kernel with H20 rom with no other issues otherwise.

That's why it's always good to keep a backup of all the data on your phone on a hard drive. Then, if you have to replace your sd card, you can just drag the file right onto it.

I would try the HP disk format tool. I've fixed several corrupted flash memory devices with it.

This seems to be a relatively known issue with specifically SanDisk 32GB Class 10 UHS-1 red/grey cards and the Note 2. When it started happening to me, I pulled out the card, tested the crap out of it like a dozen times, reformatted the card in my PC, and put it in my Acer A500 tablet and put the Patriot 32GB Class 4 that was in the A500 in my Note 2. Both are working fine now for the past week.
There's a more extensive discussion of this on the T-Mobile Note 2 forum:

Did you remove that little blue plastic sheet covering the card's aluminum housing? I was was half through doing that before I decided that I better check the internet first.

Micro SD Card Problems

I seem to be having trouble with my SANDISK 32GB Class 10 micro SD card. When I first got the Note II in November, I had a PNY card that was giving me trouble, so I got the SANDISK card to replace it. it's been reliable until this morning, in that the card lost all data, and even after reformatting it, it seems to work for about 10 minutes, thenphone does not recognize it. It's been trouble free for almost 3 months.
I seem to read that these SD cards on the Note II is extremely unreliable in general. Perhaps I need to switch brands. What would the very very very best brand of the micro SD card would you recommend? What micro SD card would be the most durable? I've always thought that SANDISK was good, but how about other brands? I'd like to keep using a 32GB Class 10 card if possible. I'm looking to use a card that will last more than 3 months.
Also, I'm completely stock on my phone...as I did not do any rooting.
Any suggestions would be greatly appreciated. BTW...I love the Note II!!
Thanks,
Mike

I had a samsung 32gb class 10 that would keep resyncing by itself after a SD card failure. I thought it was my card going out so I bought a new one to replace it. After a day or 2 with a Sandisk one I noticed it doing the same thing so now i know its not the SD card but the reader. Havent figured out a fix yet

A class 10 64GB sandisk card has been in my Note 2 since the day I received the phone. I haven't had any issues with it, and have about 20GB of space left.

It was on sale for ~$40 last November
Running Stock, unrooted.

My wife's N2 has the exact same issue. I'm about to send it back... And she's the one that never jacks with ROMs and crap...

Since I installed saber kernel it has been happening alot . Almost every five minutes... or less.

I had issues with my SanDisk 32 as well try this
Put card into pc (windows) save any files you want to keep
Open terminal command where your car is at and format the card (I use fat32) then type
F dsk /h
Worked for me no issues since

Swapped my Sandisk for a friends PNY. Fine ever since.

my wifes 32gb sandisk also crapped out. didn't work in her phone, my note II, or pc in several different readers. tried for a few days and nothing. i put it in the pc a week later and up pops the card. quickly d/l everything off the card.
so weird

I can't believe a reliable card made by Sandisk is giving issues, guess I'll get a samsung card next time.

Had the same issue with my card, removing and re attaching constantly. Got SanDisk to replace it, just took about 7 days turnaround time. New one is still working fine. Let's hope it stays that way.

Contcted through their website first, then called their customer service number for their site. It will go faster if you tell them it is mounting and un mounting in your phone and doing the same on your computer. Because my computer would register it, I they wanted to wait and see if it would fail on my mac. I believe the response to my online query through their site got me response to send it back. They sent me a packing label and everything.
Sorry to ramble, but go through their site and you will have a new one in about 7 days.
If none of this made sense, sorry, I'm tired. Pm me questions and I will do my best to be more clear. Good luck.

I've been having this problem as well. I figured it was just an issue with the phone because the card works ekse where. One thing I've noticed is when it says the sd card has been removed I can go into my files and pull up what I need. I just can't go directly into the app to open it (I.e. gallery or music player).

I have tried everything they suggest to fix it, multiple reformats, both internal and with a computer. Once it starts doing that, it won't stop. It's the card, not sure what, but it's just a bad card.
My new one is working fine, so far.

Note 2 killed my Sandisk Micro sd HC card?

First, sorry for my bad english. i hope you will understand my problem.
I am using a genunie sandisk 32gb micro sdhc card. used it with my old xperia t too...
Started using it with my Note 2 since 2 months. But i got an error yesterday, that my card is removed because format is not ok. i did nothing with the card or not removed from my phone. My phone was also turned on since 4 days. And today asked me for formatting micro sd card. i had no time to check it on my computer so i choosed format it. Note 2 has formatted it. After that it didnt see my card.
In the storage menu it shows no ext.card. i tried to format my micro sd card on windows and on macbook but they dont see my card.
I lost my photos and some files... i dont care about them now, i just want to format my card but i think its dead now...
Anyone has experience? What shall i do now?

Now i see this again, choosing format but nothing happens...

Do you see it listed in Disk Management in Windows? It could be that it is not being mounted as a drive, but seen as a RAW partition by the system, in which case you can format it from Disk Management and start using it again. Don't look for the card under Volumes, but where disks are listed, in which section you'll see Disk 0, Disk 1 and so on. Good luck

Try to format your card using SD Formatter https://www.sdcard.org/downloads/formatter_3/

Thanks for your replies. I will try it when i arrive to home from my work.

I had a 64GB SanDisk card. I bought it in December. Last week, somehow, it became write protected! I could not format it, either in the phone or Windows and could not write any data to it.
I phoned SanDisk and they said they would replace it. I managed to copy the data off it. I told them I couldn't send the card back to them, as I couldn't delete the data. They just asked me to photograph the card before and after I cut it in half. Now they are sending me a new card.
However, as there seem to be many problems with SanDisk cards, I will never use one again. I bought a Samsung 64GB instead.

Don't think its the phone, rather the SD card itself.
after getting a Samsung MicroSD card, there are no further problems.
the Sandisk card even has problem being detected by a windows 7 machine

Sandisk and Lexar are both garbage! They have the worst quality control ever. I don't even understand how they are so popular.

I have mailed to Sandisk support, they wanted photos of card with serial number and where i bought it.
than they want me to break my card and send again photos of broken card. Now, they will send me new card...

Had the problem myself with a 32 gb sandisk class 10. The phone said the card was damaged. I used the card adapter that came with the card and when inserted in my pc card reader, surprise: it worked like nothing happened! Saved data, format it with sdformater and i use it now.
I mention a kingston card adapter didn't do the job. It kept saying the card was not formatted.

Yes SD Formatter is kind a low level formatter. If flash storage is not physically damaged, SD Formatter solves most of the problems

defo not the phone but the card itself. Has happened to me more then once. Some card's are just ****

well from personal experience. I have to say first hand, i honestly think its the phone. the same thing happened to me. i have the att note 2 and a centon 32gb class4 card and out of nowhere, i get a message that my card was removed unexpectedly and now my card doesn't work on ANY DEVICE. I've tried multiple card readers, different software, different computers, even tried a mac, took my memory card to s specialist. NO DEVICE recognizes anything even connected. now i thought, ok maybe a faulty card but my wife with same phone and a sandisk 32gb class 10, SAME THING happened. my friend with a Kingston 32 gb and a sprint note 2, his memory card died as well. THREE different brands, and same type of phone. too much of a coincidence, could be it really cant handle 32gb. now im using i think 8 and its working fine for now.
google this problem and youll see its a bigger problem then you think. BACKUP YOUR DATA, i had to learn hard way. :crying:

Happened the same yesterday. Trascend class 4 32Gb SDHC. Completely dead.
Checked with a macbook, but the card isn't detected anymore.
In my opinion, the NoteII may haves some problem with sd card (maybe the voltage regulators aren't correctly programmed, or something similar).
But frankly, I do not have any proof to support this, just a sensation.

I had the same thing happen to me. Put the card on a windows machine, and run
chkdsk /f
this makes the disk readable again. At least, it did for me. One problem was that even though the disk was readable, it seems some
files had errors, so the media scanner ran forever and used up lots of battery when the fixed card was used. I ended up not using that card any
more.

Same problem with me... 32gb microsd hc class 10 sandisk... In sn2 n7100 it says blank card or unsupported filesystem... In windows 7 laptop... It is not detected.... Chkdsk does not work in cmd prompt as the card is not detected... Unable to do anything with the card as it is not detected... Cannot format, cannot see in disk manager. Card is also not read in other phones.
PLEASE help as it had a lot of information and i have NO money to buy a new card.

just had a 32gb sandisk ultra micro sd die in sg4

Bought this ultra micro sd class 10 sandisk about a year ago. Had it in my htc amaze until may 1st when I got the s4. Today my sd dissappeard. I ejected and inserted multiple times but the phone wont even acknowledge it has a sd card in it. Bought a new identical sd card and it was recognized right away..
plugged bad sd into computer and the computer didnt acknowledge having it plugged in until the 5th time I tried.
was able to copy all my files thank god. 24gigs of work and info almost lost..
anyone else think the sg4 did this some how or could it just be a rotten sandisk micro sd?
input greatly appreciated.

SanDisk had issues with the 32/64GB MicroSD's; im on 64GB number 3 right now, which has worked fine for about a month (the first two would randomly dismount usually once a day on my Atrix 4G and also stop responding on my PC randomly), this one does not. Try getting it replaced or getting a different brand. Normally SanDisk is pretty rock solid (i use sandisks exclusively at work as they are the only certified cards for the recorders i use, and the only brand ive never had problems with. i use mostly CF and also sometimes SD/MicroSD)
Honestly i think the MicroSD thing is all SanDisk related; specifically to 32GB and 64GB Class 10's (the gray/red units). The older 32GB Class 4 black MicroSD's dont have issues.

Crazy update. 2nd 32gb ultra micro sd un mounts and mounts every 9 seconds. Or if you tap the card or shake/move phone slightly it un mounts and re mounts.. I put in a 1gb sandisk black class 4 micro sd and shook and tapped phone over micro sd and it did not unmount at all stood in fine.
this is terrible quality on sandisks behalf. I dont even know if I have receipt for them. I bought both at bestbuy tho...

I bought a SanDisk 64GB microSD card at BestBuy. So far so good works like a charm...*knocking on wood*. I had a 32GB Lexor that I used in my Sensation 4G and it died on me after about 2 years. Was not able to recover the data either. I did backup the data every 2 - 3 months, but still lost a lot of data. :crying: With the S4 I'll probably end up backing up data about every 2 weeks just to be safe. The free 50GB from Dropbox came at the right time.

I bought a samsung 64gb since i read a bunch of reviews that said the Sandisk 64gb would randomly lose all the data on the card and the card would just die. Some said a week after getting it, others said months. I didn't want to risk losing all my pics and stuff

Glad I'm not the only one having issues. I bought a 32GB card and had a bunch of issues with it. It would unmount randomly and the gallery was always slow to load up the contents. I bought a 16GB one and it's been fine. Very fast to load, no issues. I ran an hour long SD card test on it Saturday and it passed with no issues and decided to try it again and so far it's been perfectly fine.. Weird.

i had the same issue with my S3 and my SD card it would just become unreadable out of no where..
if your stock then the only reason i can come up with is nolonger valid
I think i'm going to start utilizing these instant sync apps (G+, Dropbox) just out of fear of losing pictures

There are already multiple threads on this. if you get a damage sdcard warning, plug the card into a PC, open cmd & type chkdsk /r /f <drive_letter>. it will take time to fix your sdcard. Backup your data & reformat if you wish. I get this occassional but with chkdsk I'm have no worry since I can repair & already have backup in place.
With that all said, it is disappointing to have to go through this. What I noticed so far is that it's only happening on my exFAT & FAT32 formatted 64gb sdcard for me. I never had this kind of issue on my 32gb sdcard.

I think this might work
I've been having issues with my 64gb sandisk ( unexpectedly removed error ) & remounting or formatting has not done the trick until now. Formatted card to fat32 with my PC which I have done multiple times & still had issues, but now after a fresh format to fat32 using my PC I decided to format with OUDHs recovery under mounts and storage - format extsd & have absolutely no issues as of yet. No more errors finally. Lmk if it works for you guys.

Thats weird. I've had the same problem with my 32gb sd card i thought it was just the sd card but it seems like a lot of other people are experiencing this as well...

SD card unexpectedly removed.

Anyone else getting this message? I put in my 64gb SanDisk Ultra and have been getting it intermittently since day 1. Almost always when I open camera or gallery. I reseated the card, took everything off, formatted and everything to no avail.

samsung and SanDisk 64 gig cards are an awful mix. my s4 killed my 64 gig card and I got it replaced. new one worked fine... didn't use it for a while bc i had the g2, but i used it in my digital camera and it was perfect. then I got the galaxy tab s in July and put it in there... by October, the card is dying again. keeps randomly unmounting and stuff. it's a Samsung and SanDisk issue. I have a 32 gig SanDisk class 6 that works fine and never corrupts but the 64 gig class 10 always corrupts. people have this issue often. I'm actually gonna buy a Samsung 64 gig card as many people did that and they say it doesn't corrupt like the SanDisk does.

Thanks for the info. Just strange because I've used this same card since the note 2. Only this phone has given me issues.

Have you try to format the card using the note 4?

Me too. I had my Scandisk 64 gig card in my note 2 for 2 years no issue. As soon as I got my note 4, I have been having this problem randomly. Seems to be happening less as time goes by.

I used to get that with my note 2. Supposedly it's a loose cable connector. If I placed my phone on the table, the force of the placement would cause my phone to say that. I really hope my new phone won't develop this over time. Maybe you can try to test it by slapping it into your hand (that used to trigger it in my n2) btw it's not specific to the card manufacturer because I had the SanDisk 64 class ten and now have the Samsung 64 class ten and they both did it in my old phone. You should try to see if you can get a replacement if you can replicate it in the store.

The same thing has been happening to me. I have had a 64GB SanDisk Ultra card since the Note 2 and it hasn't caused any problems. Now with the Note 4 is is doing this all the time. I have formatted it with the Note 4, reseated it, and it still is happening. I hope they can fix it and soon.

Also, btw it was not specific to a firmware/software/kernel because my N2 had many many versions of touchwiz, android, and cm on it and they all did it.

I used this card on my note 2 and note 3. It still works fine in my note 3. I took everything off and formatted it on the note 4 itself. I then left it blank and didn't get the issue. However as soon as I take a picture, try to send one via mms, or play music(I downloaded a song to sdcard), I get the error. It almost seems as if everytime it tries to access anything on SD card it happens. I'm going to take it in and see what they have to say about it. I'm sure they will tell me it's my sdcard. Even of they replace is what are the chances it will do the same thing? My cousin has AT&T model and his does the same thing.

Which model/speed rated 64gb ScanDisk are you all using? There's different kinds

Ultra Class 10

I'm getting this same issue with a 64GB SanDisk Ultra Class 10 MicroSDXC card. I was about to RMA the card when I found this thread. I hope a solution is found soon, this drives me crazy when trying to take photos.

Yes! I have a 32GB Sandisk Ultra that seems to get lost on a daily basis...
Also, not sure if this is the case, but I seem to remember this was an Android 4.4.4 issue?? Or was it KitKat??

Same issue here. I yanked the SanDisc 64GB Ultra from my Note 3 when I sold it. I put it in my brand new Note 4, and it would get that error constantly. I removed it, formatted it, put it back in, formatted it again via my phone, and then transferred over some videos. I could play them a bit but it would quickly lose the memory card and stop playing. I yanked the 32gb from my GoPro ,formatted that, and it's been flawless ever since.
I wish I had an answer too. I got this phone partially because I like having a lot of storage space available.

I had the exact same issue with a SanDisk 64gb card. Thankfully I had purchased a Sony micro SD card not too long ago. Put it in and haven't had any more problems. Very strange that it seems to only be SanDisk cards having an issue.

My Scandisk 64 gig was solid in my note 2 for 2 years. In my note 4 it does it like every minute or so.
Put it back in my n2, rock solid. It is not the card. Now here is the weird thing, I took off the back cover and rock solid. If you look at the inside of the cover the is a little bump I think to help secure the card. I think that is the issue.
Try to perform some stuff on the card with the cover off. Let's see if it really is this simple. Report back with your findings. I am interested to know.

When I was first having issues with the card, I got sick of removing the back, and left it off. I still had problems.

I have had zero issues with my card. Again. It is not a SanDisk error.. it is model specific. When getting the note 4 I went with an SD card that is 4k data compatible. Yes.. ordinary memory cards will not like 4k data. Is that why yall are getting errors? I'm not sure but it might have something to do with it. That a data transfer rate must be able to handle the pics and videos we create with this high end device.
I have this one...but in the 64gb varient.

Again, absolutely zero issues since I've loaded the card into the phone.

Thanks! Was hoping this was not the case, but I broke down and purchased a PNY Class 10 4k micro sd. Works great, no issues.
Thanks,
Bill
