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.

Same problem here. Had the 32gb sandisk class 10 for about 3 weeks and now everyime I turn the phone on it said sd card unexpectedly remove. Tried switching to the pny 32gb class 10 and the same thing happened. Is there a fix for this, and how is the samsung 32gb class 10 sd card?

My 64 gb class 10 sandisk works great, its in my second phone now. You have to be careful when you remove them so you minimize scratching and damage it.

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.

[Q] Micro Sd(s) not compatible with?!

So as a new android user (switching from apple) i realize how much i've been missing out on the beauty of Android devices. So that being said i am so happy to be here and posting about this new friggin device!
SO heres the problem that i realize: Most micro SD card does not work with this new device!! I've tried installing it in the note 10.1 and realize that in the end it cant read. However, if i put it in my s4, it does read and store data. So i emailed samsung personally and they basically said, "as of right now, there arent any micro sd card that is compatible with the note 10.1 2014. Can anyone confirm this? Has anyone used a micro sd card with their device yet? If so what brand? I have a kingston.

I am using 32gb Kingston with no issues. If it is recognized by your phone, try formatting it inside the phone then put it in the tablet. Most likely the card is not formatted properly.

Yeah it's most likely this.
I'm using a 64GB SanDisk Class 10 card formatted to exfat.
Plenty of help on the web if you are unsure of what your doing.
Good luck!

i tried a brand new PNY 64GB formatted to exFAT. it worked fine until it die- two friggin days!
now i'm using my back up 64GB sandisk. it's working fine so far, exFat too. had one incident that made me think that this may be a dud too, or that the 2014 may be killing my disks. i'll have to keep an eye out.

There are way too many reports of this for there not to be a problem! I myself had a card that worked great in my old Note 10.1 and my cell phone but had to be formatted for the 2014 edition. Why? No reason other than something just ain't right somewhere!

That's what I'm using too, though Kingston makes good memory, and I've had good luck with other companies as well, like Patriot and Trend Micro.

Have not seen way too many reports of this problem with this particular device. The problems lie in the the memory cards not the device. Flash memory is notorious for just flat out dying or not working in certain devices. Sandisk or Samsung are the top choices for broad compatibility, hence the fact that their prices are usually higher. Probably due to more R&D and testing. I just swapped my 64gb Sandisk for the Kingston 32gb with no issues. I had the 64gb in an Acer W3-810 Windows Tablet.

My bad. There is only this thread and another thread on the next page. It is kinda suspicious that my 64GB card as well as others here works fine in my other tablet and phone but just won't work in my new 2014. Call it what you want but to me that's a lack of plug and play!
For everyone without any issues of course we are just making a mountain out of a molehill but for us FEW sitting here with a 64gb micro card that won't work consistently this is a fail!
So yes I surrendered and picked up a 32gb card and it works flawlessly.

i have a 16GB patriot Class 4 that i pulled out of my Nook Color (and formatted on my computer) i have had no issues using this.
one thing i did notice, is that the sd slot in the galaxy note 10.1 is pretty deep, i cant get the card in without assistance, usually from a pen or key that happens to be nearby.

Do not make this in to something personal. Please read what I typed. I was not trying to deny there is a problem but let people know where the problem comes from. One android device works with a card but it will not work with another. It is more than likely the card. You made it sound like it is Samsung's fault. They cannot test every card with every device ever made. People should be asking for help from their card manufacturer. My original 64gb died right out of the box and Sandisk replaced it.

I'm sorry if this came across as personal. I apologize for that. We just disagree and that's fine. You think it is the card even though it works great in 3 other devices, my laptop with the insert, my phone, and my old Note 10.1 and I think it's the 2014 edition because it doesn't work in it. To me if it was the card it would give me some sort of trouble in the other devices.
But to each his/her own.

Maybe its how the card is formatted?

I may be mistaken but I believe I have mentioned that I formatted the card while using the Note 2014. I also formatted it on my PC. It's no biggie anymore since I have a 32 gb installed that works great. I'm just going to wait till another update and try it again. I believe it's going to work at some point.

32gb class 10 Samsung micro sd card works perfectly in my Note 10.1 2014, TAB3 8.0, GS4 & GS3

I'm having intermittent failures with my card also. I took my 32 gb Lexar out of my Transformer Prime and it wasn't recognized by the Note. I formatted it, it was fine for a few days, now it's telling me that the card is blank and/or unreadable. I formatted it again using the SD Formatter. I'm adding music to the card now and I'll be keeping an eye on it. I'll buy a Sandisk if this continues. I'm not at a risk of losing data, so I can experiment a little.

Don't cheap out on crappy low end cards, and you *should be fine. I have a combination of 6 Samsung phones & tablets all using one of the two cards listed below. Have never had a single issue, and a few of the devices have been using the same card for well over a year.
SanDisk SDSDQUA-064G-U46A Ultra 64 GB microSDXC (UHS-1) Class 10
Samsung Electronics 32GB microSDHC Extreme Speed (UHS-1) Class 10
The 64GB Sandisk Ultra is currently formatted ExFAT, and has been working just fine for almost 2 weeks now in my Note 10.1 (2014 ed).
* There is always a chance with failure, as with any electronic component, but good storage cards are worth their price.

Kingston, Transcend, Lexar, AData, G.Skill and Patriot are all good brands as well.

Same issue as above posters, I have a SanDisk ultra 64gb. After mucking around trying to get the same card that worked perfectly in my original. 10.1.
Solution : I backed the card contents up on my pc and then formatted the card in the original 10.1 before checking that I could write a new directory on the card using the 2014 edition.
Seems to work so far, hope this helps you guys (who still have the original 10.1 as well).

I have a 64GB Patriot class 10, No issues. Thought I would chime in.

Anyone try the Samsung 64GB micro SDXC? I can only guess all Samsung Micro SD's will work fine.

So which Micro SD card DOES work? Please Report in.

I thought I would start a thread on which Micro SD cards were recommended vs. those that fail early or are simply not compatible. I saw a thread earlier that appeared to show that some cards (and sizes) were better than others.
I can report that the Samsung 64GB card (says Class 10, HC, 24MB Read, 7MB Write) does NOT work in this tablet. I was able to use it just fine in my Note 2, and a laptop. However, the card doesn't work properly in my 2014 Note 10.1. An older Pansonic 16GB MicroSD card worked just fine however. I've tried formatting it in other machines, and it's still a bust. Currently, these cards are selling like wildfire on Ebay for $30.
So, what DOES work for a 64GB card? Any help is appreciated by myself and I'm sure a lot of others reading this forum.
Thanks in advance.

I have got a SanDisk 64GB card in mine. Also got the same type in My Note 3.
The SD card issue seems a bit odd, both of my cards were also fine in my older Note 10.1 and the Note 2. I've never had a problem with either of them

Samsung 64GB works just fine.
I have a 64GB Samsung MicroSD and it works just fine, haven't had to do anything to it, worked right out of the box.

This is the exact one I purchased

i've tested my 64GB sandisk on my gn8 for a week now with no issues at all. one day after being put back in the gn10.1 2014 and it's acting up again. files, fail to delete, wrong size reported, inaccessable, etc. the 32GB sandisk works fine. both are uhs-1 formated exfat. take it out without reformatting and it works fine on my gn8 and pc. put it back on the gn10.1 and it won't mount without a reboot.

Hey guys, thanks for the info. After some research I discovered that this was indeed a fake card I ordered from Ebay. Looks like this is a common problem as the packaging is *almost* perfect and you really can't tell the difference without some serious research. Luckily, the seller refunded the full amount back to me. Based on your feedback here I've ordered a SanDisk Ultra from Amazon.
Thanks for the help and & Happy Thanksgiving!

A really good way to check them is to simply try to fill it up. Only 4G of data will be saved and readable, whereas the other 60GB is corrupt.

It's sad that a lot of people get duped into buying fakes. But sites like ebay don't/can't do anything about it.
Memory cards/Usbs should only be bought from reputable sellers only (Amazon, Currys, Play.com etc) as there are wayyyy too many fakes out there.

I'm currently using a Transcend 64GB SDXC UH-1 Class 10 card which was formatted using the tablet.
It works fine except for one annoying problem. When transferring large, singe or multiple files, say 1.5GB+ HD movie or a huge amount of photos, from internal to external storage, the device would freeze. After it starts up again i notice that i can no longer access my SD card even though the device says it's still mounted. The only way i can fix this is by removing and reinserting the card or rebooting the device. Although there's no problem transferring files from a computer straight to the SD card.
Anybody encountered a problem like this? Is there anyway to fix it?

Yes, I'm having the same issue. Except the SD card will randomly lose the files even though it still shows the card is still mounted. Just recently I was watching a movie from the sd card and this happened.
I am using a SanDisk that was being used in my note 2 for the past year (never had problems with it before).
This is especially frustrating when trying to sync files with Plex.
Anyone have any ides?

I know I'll sound like a noob, but my 32gb Samsung micro sd card just doesn't seem to work on galaxy note 10.1 2014, yet it worked perfectly fine on my previous note. Would i have to format the card on my computer? A little bit annoying since I don't have a reader for it.

My Sandisk does not work
I have a SanDisk Ultra 64 GB microSDXC Class 10 UHS-1 Memory Card 30MB/s SDSDQUA-064G-U46A that has a lot of problems working in my GN 10.1-14. It has worked fine for a year in the old Note 10.1. The New Note would not even format it. Formatted it in my Galaxy S4, and it kind of works. Often it simply reports no files, although it will report in Settings the correct size and space available. Sometimes I have to reboot several times for the card to work. then sometimes I will try to open a file and get an I/O error. Then sometimes random reboots, especially if I try to unmount it.

I use a Samsung Pro 64GB microSDXC (UHS-1) Class 10 card (MB-MGCGB/AM) reformatted to FAT32. Works great. I've been using the same type card on my LG Optimus G for almost 8 months 100% problem free (also formatted to FAT32). I did have issues with a SanDisk Ultra 32GB in that same phone that used to dismount itself all the time and I know others that have had issues with SanDisk cards in GoPros as well.

ok, so which one of these sandisk ultra microsd cards will work in the 10.1 2014 edition, and what is the difference between them?

Micro SD Cards and Early Failure on the Note 3

Morning,
Purchased a second Lexmark 16gb SD card for my Note approx 2 weeks. Randomly picked my phone up yesterday and noticed there was some kind of warning on my status bar, went to check it out and it related to some kind of memory card issue or failure. I don't recall exactly what it said, but I do know it pointed to an issue with the card.
Now the reason for my post, I'm not sure what the odds are on two SD card failures in a three week time frame, but that's what I've just encountered and was interested in finding out if it's a more widespread issue, or just plain bad luck on my part
I had one 16gb card for my Note 2 with zero issues, now I've gone through two on my Note three in just over 3 months. Yes the card is fried as my desktop doesn't even see it when I plug it in via USB adapter.. Just in case you're wondering if I checked it elsewhere..

Try formatting it via your phone. This should always be the first step b4 using it on anything. Could just be a faulty usb adapter too try another card reader and or different pc/adapter.

after my S3 having problems with micro sd cards, i have stopped using memory cards entirely for any samsung products. They tend to fry the sd card every few months.

I've had a 64 Gig SanDisk since I bought my S3 zero problems. It's made it thru my s3 note 2 and now the n3 So I guess it's just hit or miss. Sorry Steve that sux dude

I had the same problem you've described with a 32GB SanDisk card, my phone kept saying the card was unexpectedly removed, then it would re-mount the card. The most annoying side effect of this issue was it caused a lag with turning the screen on, it would literally take 3-4 seconds for the screen to come on after you pushed the button. Replacing the card solved this immediately. We'll see how long the 2nd card lasts.

Yeah, that pretty much describes exactly what was going on. After I seen the original sd card warning my phone got really laggy and wouldn't even boot into recovery. Remove it and everything is fine..
Every now and then I like to completely format, which is why I like having the Ext SD card, but not if I keep having to toss 30-40 bones down the tube every couple of months..Kinda lame, should have kept the damn receipt.. lol

Just had this happen to me today on a Verizon Note 3.
SD card completely dead. I wasn't even using it...AT ALL! Will not recognize on my laptop using the SD card slot.
Battery was heating up & draining too. Crazy! Over a 3 minute period I watched the battery percentage drop 4%-5%
Oh well. Why do these devices "eat" SD cards?

I encountered the same problem a year ago with my Note 2. Fortunately it wasn't the card. I was using a custom kernel that didn't recognize the FAT 32 I had the card formated to. SInce going back the stock kernel, I've had zero problems with the SD on my N2 or N3. Anyone using a custom kernel?

Same here. Mine went thru Samsung tablets as well. S3, S4, N2, N3, Galaxy Tab 3 8.0

Lol 4th one. SanDisk sucks. But lifetime warranty. They keep replacing.
TWEAKED N3

Lexmark isn't the greatest brand of SD cards. I generally only use sandisk or Lexar and I've never had a problem.

SD card unexpectedly removed error

Anyone else getting this error? I have a 64M SanDisk that was working just fine in my note 2. I put it in my notes and I continually get this error. I unmounted, removed and power cycled my phone but it comes back any time I try to access the card. Any ideas?

I would backup the contents of it onto your computer and reformat the card. Then try it.

I've been getting this error when my phone wakes after being idle for a long time. I've tried reformatting the card but I'm skeptical that will fix the problem. According to many online threads, this issue has been widespread across a number of devices, and my card (Sandisk 64GB Ultra CL10) works fine in other devices. Will report back.

This is a common problem with the Samsungs...There is a proper process, as follows.
First, go ahead and do a fresh format of the card and get the contents onto the card.
Second, turn the phone completely off AND REMOVE THE BATTERY.
Put the card into the card slot, replace the battery and power the phone back on.
This has been my process since the sII, and haven't had any issues, save a few completely corrupted cards which were unsalvageable. There is an issue where the card receives current from the battery, and in some cases can corrupt the card and in even fewer (but still entirely plausible cases) completely fry the SD.
I'm not sure why Samsung hasn't caught the issue, or even acknowledged it, but this process avoids it entirely.
Hope this helps

Thanks, I tried that but it made no difference.
The uSD card continues to work fine in my other devices, and diagnostic tests reveal no problems with it, so I'm confident the card itself is ok.
I'm trying another card now (this one 32GB), but I'm guessing the problem will occur with that one too.

Sounds a lot like what happened to my last card in my Note 2. I was able to get a replacement under warranty and haven't had a problem with it happening since.

Well, my guess was wrong. The 32GB card I switched to is actually working fine--no recurrences of the unexpected-removal error.
So I guess there's a problem with the 64GB card, even though it was fine until I switched it from the Note 3 to the Note 4 (and I handled the card carefully).
Good thing, though. It's easier to RMA the uSD card than to exchange the Note 4.

was it an SanDisk card? I have problem using my 64gb SanDisk in my s4 and note3. I changed over to a samsung brand and now I dont have any problems.

Yup, SanDisk Ultra 64GB. I had no problems with it in my Note 3, though.

I have a scan disk 64GB card that I took out of my Note 2 (rooted) and put in my Note 4. I started getting random unmounted errors.
Finally last night I pulled out the SD card and threw it in my computer. Sure enough it came up and said I had some corrupted files. I fixed the files. Dumped the SD card to my HD and then formatted the card in my phone. Then I put my music, pics, videos, and a couple of files for apps aback on the disk. So far no more SD card issues.

Glad that worked for you! My PC, though, reported no errors when I scanned the card, both before and after reformatting.

Just got another SD card removed error...grrr

I picked up a new 64GB card, made by Samsung this time, I put it in last night and formatted it.
I had to reinstall a few apps after that.
I am going to give it a few days and see how it works out.

Flickr gives you a free terabyte of storage that you can auto-sync your phone's photos to. That way you don't have to buy a large SD card, and you don't have to worry as much about losing photos due to disk corruption.

Yeah, I tried formatting my SanDisk several times and kept getting the same issue any time the phone tried to access data or write to it. I put in an old 32M cheapo brand and have had no issue at all

3 days and no errors. Maybe the Note 4 doesn't like SanDisk brand SD cards?

I have a SanDisk from my S5 in my Note 4 and it has been flawless.

I'm happy to report that the RMA replacement for my Sandisk Ultra 64GB uSD card arrived today (the replacement is a Pixtor rather than an Ultra), and so far it's working flawlessly.

I have been dealing with this error with my Sandisk 64gig also. Didn't have a problem with it on my Note3. I have reformatted to numerous formats. Anyone know of a specific one that works. Always have had trouble out of Sandisks on Samsung galaxy products. Some I don't , but I have had this problem on at least 5 different devices. I have always read that the thing to do is go with Samsung brand SDs. The new 64gig Samsung is apparently faster than any other micro SD. However, since I have paid for this one, I'd like to use it.
