Guess this is mostly a canadian concern, but has anyone else's external SD mysteriously been deactivated when the phone is exposed to temperatures below freezing for relatively long periods of time ?
For example, taking a walk outside for +/- 30 minutes when the temperature is around -10°C (~ 14°F).
It behaves exactly as if it's being manually deactivated in Setting --> Storage.
The card comes back to life after leaving the phone untouched for 5 minutes on the table upon returning to "normal" room temperature (~ 21°C / 70°F).
Never encountered this issue with the exact same SD card in my good ol' GS1 (i9000m), so I'm wonderring if it's the GS3 that doesn't tolerate the cold very well of if it's my SD card that's getting old.

EDIT
It was indeed the external SD card that seemed to be the problem. Switched temporarily to a 16Gb SD from my old GS1 i9000m and couldn't reproduce. Have bought a Sandisk Ultra 64Gb Class 10 micro SD card since then and couldn't reproduce with it either.
Glad it's not the phone! :victory:
Re: External SD vs. cold temperatures
I've had stuff like this happen, (Canadian as well). I always thought it was due to moisture but it's never been a big issue
Sent from my SGH-I747 using xda premium
Normal Operating Temperatures for SD Cards are: -13ºF to 185ºF (-25ºC to 85ºC)
There's a possibility that the SIII can't read the SD cards under cold conditions?
I'm not 100% sure, as I've only owned my S3 for a week and a half, and still playing and tweaking it..
I also live in Canada (Montreal), so our weather conditions are about the same.. So i will let you know if i encounter this problem or not?
I would try to re-format your card?? maybe that will help??
Use the Panasonic SD Formatter Software for Windows, and then I format inside my S3 for best performance.
Try that, maybe it will help???
It's an issue when :
Your camera is set to record images/videos on that SD card and you want to use it
You meet someone on your way and want to show that person pictures you've taken

If you're courageous enough, go take a walk outside today, or this evening, and see if you can reproduce.
Temperature a freakin' cold enough for it to happen these days! lol
Also, it's been discussed that most people think that SanDisk Extreme III is the SD card for extreme temperatures.
Which brand? is it?

Lexar 16Gb ... class 6
But like I said, this exact same card used to be in my GS1 and never encountered this issue back then.
Re: External SD vs. cold temperatures
I had an issue last week where, when I was outside on a job site, my sd card became corrupted. Lost everything on it and the card was damaged so badly I couldn't even reformat it to get it working. Had to get a new card. Don't know if it was coincidental or not. It was only about -4 C.
Mine got corrupted as well the first time as I didn't expect this to happen.
I kept trying to access it up to a point where when it was available again it got corrupted.
Had to format it and lost everything.
Since then, when this happens, I let the phone sit for a while and never had data corruption since.
Still curious to know if this is phone or memory related...
It was indeed the external SD card that seemed to be the problem. Switched temporarily to a 16Gb SD from my old GS1 i9000m and couldn't reproduce. Have bought a Sandisk Ultra 64Gb Class 10 micro SD card since then and couldn't reproduce with it either.

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 know man, i like sandisk but i have had issues with their cards since the s2. I just ordered a 64gb samsung off of amazon. You should give samsung a go.
Nvr had one prob any sandisks in my Htc devices.. I guess this is a underlying samsung issue

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...
Hi people I have a little problem, I had buyed a Micro Sd 32gb Class 10 Ultra for mi Tab 3 7.0, the tablet show the 32gb, but the problem is when I tried to create folders or copy thing to the sd from the same Tablet, example: copy music from Sdcard0 to extSDcard and say "error could not be writte to"
I probed the Micro sd in a THL W5 and in LG Optimus L5 2 and works Fine, in my pc also works fine, the problem is with the tablet
(I have formated the Sd a lots of time but the problem persist)
anyone know what is the problem? This tablet support ultra micro sd?
SD cards have been annoying the crap out of me for the past week. Between discrepancies between how my PC reads em and how Android (or at least the T211) reads em, difficulty xferring files via USB, etcetera....personally I found out the bulk of my problems had to do with: an Amazon marketplace seller sold me a counterfeit SanDisk card, and before I realized the card was counterfeit (and more generally how prevalent counterfeit cards are), I purchased a Samsung 64GB card off of Ebay, turned out to be fake as well. The SanDisk fake was convincing, the Samsung as well although all the white text on the SD Card wore off within days.
Anyways I bought a legit SD card yesterday, and encountered similar problems to what you are having. IMO, save your files, and re-format the SD card using the tablet and not your PC, if you haven't done so. If you have done so, don't know what to tell you.
Hello,
Anyone has problem with the microSD card being ejected when writing on it ? I have that when I take a video or multiple photo in line, even when I run a backup with Titanium and the phone is just on a table, without moving it.
I use this one: http://www.amazon.co.uk/gp/product/B007JTKM30/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
I use it for months on my macbook with a nifty drive without problem.
I've had this happen myself a few times. Then my SD card got mostly corrupted, but it wasn't new, I had a 64GB Kingston Class 10 SD Card that I've abused and over used for the last few years coming from my Epic Touch 4G (Galaxy S2), Galaxy S3, and now LG G3.
My best advice:
ALWAYS backup your SD card every three months onto a computer and external hard drive, and replace your external hard drive and SD every three years if you're a heavy user (just to be safe).
I installed a newer 32GB Sandisk Class 10 (until I replace my 64GB card some day) and I have not once had it "eject" at all since. So that's probably heads up that your card is failing. Whatever you do, don't format it and keep using it, it's on it's way out from the sounds of it. The thick bars/lines in the photos are a good warning. Buy a new one as soon as you can, for now try to stick to internal storage.
Yeah, it's possible, I will try with a new one. Thank you
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.

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'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.
