External SD vs. cold temperatures (solved)

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.
Glad it's not the phone! :victory:

[Q] SD Cards Burning Out

I have an unlocked Rogers Samsung Captivate Glide (i927R) running gingerbread (since Kies doesn't want to update it to ICS, and I haven't gotten around to rooting it), and it seems to be eating through SD cards. I had a 32gb micro SD card in there, but the phone decided to stop reading it after about a month and a half. Nothing else can read the card either; not my computer, not another phone, not even my camera can read the card. This is the second 32gb card it's happened to, and I'm starting to think that maybe it's my phone. When I have the card in the phone, it simply says "Unavailable" when I check under storage, although the phone can still read other SD cards.
Does anyone else have problems with this phone (i927R) killing SD cards? Am I simply just overloading the SD card, or is there some possibility that the phone is burning them out? Should I go for a 16gb card and see if it doesn't burn out, since smaller cards seem less likely to burn out?
Any help is appreciated.

The last one that burned out was a Transcend, and I don't remember what the first one was. but I don't think it was a particularly high quality brand. I will be sure to get a better quality card next time.
Do you think downsizing to a 16gb card would reduce the chances of a burnout?

It's a crapshoot man ... I've had kingstons bad out of the box at a couple of sizes, the flash drives I had die were 16gb Corsair USB3's and rated with high speed..
just make sure you get a class 10 and read up on some reviews ... Newegg is really great for it, lookup the brand, price etc. and then to buy it at a local store and have them price match...
I should really get in the habit of backing up all the information on my phone more than once i run out of space
*EDIT* .. The current one I use is G.Skill 32GB .. Lifetime Warranty. Comes w/ full size SD adapter.

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 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
Sent from Flip's Galaxy S4

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...

microSD ejected

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

HTC 10: A devourer of SD cards?

Hi!
Today my SD card died and took some pictures with it to the grave, fortunately nothing very important. It may not have been the most expensive card, but it was a fast one and I used it as internal storage. It didn't show any signs of deterioration before it died. I tried to read the card with my PC and two tablets but none of my devices is able to even see the card.
Before buying a new SD card I want to ask a few things:
Does the HTC 10 have more problems with SD cards than other phones in your opinion?
Should I use my new card as internal storage again or do you recommend to use it as external storage?
Is it worthwhile to buy an expensive card? I laid my eyes on this one: SDSQXCG-064G-GN6MA (SanDisk Extreme PRO microSDXC Memory Card Plus SD Adapter up to 100 MB/s, Class 10, U3, V30, A1 - 64 GB). It costs about 50€.
I hope that you want to share your thoughts with me.
Regards,
Benjamin

If the card was inexpensive and fast, I would think that the compromise made was on build quality/reliability. Using the card as internal storage will wear on the sdcard more than using it as external storage (more reads/writes, more heat) because it will store apps and app data on the sd card.
I don't think the HTC 10 has a problem with sd cards, I haven't heard this issue come up before.
If you have enough space for apps on the internal storage, I would recommend keeping the sd card as external storage.
However, if you still need to use a card as internal storage, you definitely want to get a more expensive card.
Sandisk extreme pro is a good choice because it's made for use with devices like GoPros that do constant writing for extended periods of time, meaning that they can handle the heat that builds up when constantly writing to the sd card.
Sometimes it could really just be pure chance, maybe you got a bad card that died early, but I definitely think it would have lasted longer as external storage.
I'd be interested to know if anyone else has had a similar problem with any phone with an sd card as internal storage.

The thing is - current sd card technology is not suitable for adoptable storage. Multiple read write proceses are killing memory cards. So, until someone makes a card that can take the beating of multiple read write proceses, just use your card as it's ment to be used - as a removable storage and you'll be just fine [emoji6]

Thank you both for your well formulated and competent response.
I've taken all these points into consideration when I chose to use my first SD card as internal storage. I really would like to know if a high quality card could last the expected lifetime of my HTC 10 when using it as internal storage. I wanted to avoid the limitations Google imposed on write access to the external card but when I saw the limitations of the internal storage solution I was unsure if it was a good decision.
It's good to hear that you do not have the experience that the HTC 10 has a problem with SD cards. With that information in mind I can buy an expensive SD card with good conscience.

Let's hope that more users are going to share their opinion with us.

I've just sent back my second SanDisk Extreme PRO card in 18 months. The first one stopped working after just 4 months in the HTC 10, the second one a few weeks ago. The circumstances were identical, I wrote larger amounts of data in a short time and the phone started saying that the card has to be formatted. I could use a reader connected to my laptop to get most of my data back, but the phone insisted on a format. I'm not sure if it was the SanDisk cards or the phone, either way, I ordered a Samsung card this time. Luckily amazon.de is extremely customer friendly and just gave me my money back in both cases.

I always use transcend, I've had a 128gb external SD card in since may 2016, all camera shots goto external card, all flashing and backups goto external card. Never had a problem, touch wood ?

Guys, are any of you using Spotify? I have consistently had microSD cards die after downloading songs for offline use i.e. two phones and three different microSD cards.

I use a Samsung evo card as removable storage since January, never had any problems with it. They are a bit more expensive, but it is worth it in my opinion. I use it mainly for Spotify and Netflix downloads as well as pictures (wallpapers) and ringtones... Don't use a rather inexpensive card as adoptable storage, since they are too slow. Or even expensive cards for that matter In a few years, sd cards will be fast enough, but not today. Also, I fail to see a practical use for using the card as adoptable storage as of right now since 32 gb are plenty of space for apps

I did not know that it is possible to tell the Spotify app to use external storage. Will try when I get my new card.

I'm going to buy a card produced by a reputable company this time, for sure. But I thought that cards with the A1 specification (Application performance class] would be fast enough for use as adopted storage. But you are right, 32 Gb is a lot of space for apps.

Actually, if Spotify recognises your sd card as removable storage, it even is the default setting

I've used Samsung evo and Sandisk Ultra Extreme and the both failed a short time after downloading Spotify songs!

I've had a Transcend 64GB card fail after a few months. It was inserted as external storage and I was able to recover its contents on a PC. I was able to put it back in the phone without formatting it, just tried a few times until eventually it worked.
It happened when it was very hot outside, not sure if this is related or not. I wonder how many failed cards are failing during hot weather, during heavy phone use, or in hot climate areas.
I've switched to a Samsung 128GB evo plus now, u3 speed, so far so good. Fingers crossed. Judging by this thread though, it does seem that this phone kind of eats through SD cards.

This is precisely what I wanted to know in this thread. Before buying my first card for the HTC 10 I read a number of threads that suggested this phone specifically has problems with cards bigger than 64 GB. But the reaction to my thread doesn't seem to be so hysterical to me.

I been using a Toshiba Exceria M302 128GB as external storage since the phone first launched and it hasn't failed on me yet, touchwood. Although I only been using up to around 50GB usage, I have re-download my Spotify collection a couple times.

The SD card in my HTC 10 is going on 15 months old, and it's still ticking. I have never used it as adaptive storage. It just stores photos taken on the camera (which are backed up to Google Photos). Some games offer to save data onto the SD card, so I do that as well. It's a Samsung 64GB PRO (class 10).
Not sure if the UHS-1/3 cards will fare better.
