SD-Card Error - Round 2

Hey guys,
a few month ago, i created 2 threads here.
My sd-card simply stopped working and I couldnt find the issue, even replacing the slot did not help.
Today, suddenly, my bootloader recognized the card with a PC10IMG, just tried this one out.
I could upgrade, got to the newest radio, and android 2.3 (Virtous Sense 2) could use the sdcard.
But at first, wlan did not work, so i restarted the phone.
Now everything seems fine, except that after a few seconds, the SD-Card is "unexpectedly removed". or "damaged". I cannot format the card using the phone, even in recovery menu its unmountable after a few seconds. Example: I chose "install zip from sdcard", could find the rom on it, but when it started installing, the installation immediately aborted and after this, the sdcard wont answer anymore in any way. This is reproducable by simply formating the card again using the computer.
Any ideas how to fix this?
Thx in advance..

Its possible the connections for the sd card slot are damaged or that you got a damaged replacement, or that you might have damaged it on installation. I'm leaning towards the connection on the main board being damaged in some way. it's strange that it is intermittent.

I dont think its a problem with our memory cards. Either the card slot that Samsung made is of very poor quality or it is a problem with the latest ICS firmware. There A LOT of people facing this problem out there including my cousin who is the only other person i know with an S3. Not only does his memory card slot disconnect and reconnect, it completely killed it, it does work anymore. In some situations online, i have seen that people have ruined 2-3 memory cards by putting it in the S3.
I am facing the same problem and it is getting on my nerves. I live in a third world country so I might not receive a new phone.
Please find a solution XDA FORUM! :crying:

Had the same issue with my S3.
Turned out that the SD card was dying (the card brand is Team Group), this caused it to be unmounted by itself and then mounted again (sometimes showing notification “sd card removed unexpectedly”), hence triggering the “Media” scanning process and significantly draining the battery.
I created an application to monitor how many times the SD card was removed, and turned out to be unmounted every ~3 mins!!!
I then bought a new Transcend 32GB Class 10 card (made in Korea), and until now, this never happens, no reports from the application whatsoever, and no media process eating my battery.
I just published this app in the play store now, this is the link:

I'm using aLenovo A7000 running on ressurection remix V5.5.9 in which i don't have the option to unmount my sd card.Please suggest me a way to do it and also while transferring files from my pc on my phone...i switched my phone from a mass storage device to the'charging only'option and after that my phone doesn't get recognised at all by my pc as a usb mass storage device.... And i can't even find those options anywhere in the settings and usb debugging also isn't working.Pls help me ASAP!

My 16gb SD card also does this. Before it started though, all of my music files on it became damaged, but would still play partially, then end prematurely. I think this may just be cheap ass SD manufacturing. I say just boycott SD and get the Samsung card.

Solution / Fix:
Install Wake Lock PowerManager on google play. Enable Partial_Wake_Lock then viola! No more unmounted / eject problems. The problem is everytime your mobile is in sleep mode, the unmounting error occurs.
Also install SD Card Monitor to check the counter of mounted/unmounted/ejected sdcard.
Hope this helps.

Stupidest post 2016

[Q] SD Card makes my phone hang constantly.

I have a Sandisk Ultra Class 10 64GB card. Worked great for 5 months. A week ago, my phone started hanging like crazy. First 2-3 times a day, then 20-30 times a day. I factory reset my phone, but with the same problem.
Then I removed the SD card and phone started working perfectly again. Inserted the SD card, then same phone hanging problem.
You may note, I have never got any SD error message. The phone only hangs.
Any idea if this can be repaired with a format of the SD card or is it a hardware failure ?
Help will be appreciated.

I formatted it to FAT32 when I bought it 5 months ago. Working great for 5 months. Haven't received any Read or Write errors yet.
Would the phone hang because of an SD card?

Are you using the SD card in Fat32 or exFat file system ? I had a similar kind of issue before. Remove the card and using a card reader, connect it to PC to check for possible malware/virus on the card. And then format the card completely on PC( not on phone) and most probably it should solve the issue.

Yes it can cause issue
Format it again
insert card, if there is no issue restore data after scanning with good antivirus.

The very first day i got my Note i had this problem,(samsung 32GB card.
after several resets etc same problems, it was so bad that it even crashed the radio part of the device!
I was about to return the device when i remembered that we had similar issues with the Htc pro 2 with windows mobile,
After a few minute of scanning my brain it hit me, Pictures and thumbnails!
I then deleted all pictures from the card and thumbnails and behold, problem gone.:laugh:
In my case it was a corrupted picture or thumbnail that was crippling the device,but if i use the card in other devices as the galaxy s 3 mini there was no problems there.

Use exFAT!
It's better than FAT32 and it has file support that is bigger than 4gb

Damm! Its hung twice again, without the SD card... And in the last 6 months never hung even once.
What do I do?

http://forum.xda-developers.com/showthread.php?t=1896696

Maybe it's a corrupted file in it.. Try formating it then try it when it's empty, if there is no issues then yea there is a corrupted file was in it..
Also try to make it exFAT with perseus or RedPill kernel, as far as I know, they support exFAT..

What He/She said!!!!

So this just happend to me..

Using my wileyfox swift for a few days now and having a blast. This is the cheapest phone I ever got and i'm enjoying it
even more than my Nexus 4.
Today on the other hand, something strange happened to me.
Phone was working fine with a Samsung Evo 32 GB UHS-I formatted as internal storage.
Today I decided to move some apps from internal storage to the SD. I should have never done this..
After 3 apps the phone would stop moving them and stuck at 0%.
I thought this was just (another) android bug an rebooted the phone.
I moved 3 more apps and the same problem occurred.
This time the phone got stuck in bootloop at the wileyfox logo and a soft reset solved this.
When the phone booted I noticed 6 apps had disappeared, strange thing is. These weren't the apps I moved to my SD.
After opening the app drawer my phone froze completely, another soft reset was needed. This went on 5 more times, until I
removed the SD card. After this the phone started fine.
I checked the SD in my laptop and it was only showing the folder "Lost.dir".
When trying to format the SD card it was only showing a option to format it to 16MB.
After this i used Windows build in "disk manager" and noticed that there was a second (and main) partition of 16MB on the
card(?!).
After removing this partition I could format it to the original size.
It took me 5 tries before the phone would format it to use as internal storage. It would force close 4 times before with
an error message.
Can't find anything related about this issue on Google, is this a known bug?
TL;DR: Moving apps from internal storage to SD f'ed up my SD partition/card. Can't find anything about this issue online.
Phone info:
Wileyfox Swift
Cyanogenos 13.1.2, latest updates installed.
Not rooted, locked bootloader, nothing modified.

Even if u can use sd card as internal storage or whatever is not recomended to use it. Or even move apps on it my friend lost his 32gb sd card after using app to sd or something similar i dont remember

Actually this is some solid advice for everyone.
I tried using a build in feature and it did a whole lot of staying things. Since this happened I will stay away from the feature.

SD Card as Interanal storage problem Android Pie Soft reboots on lock screen

My SD Card SanDisk Extreme Pro 64gb (brand new) is not corrupted or anything it works perfectly fine from other devices. When i format the sd card as a adoptable storage it soft reboot or somehow like the sd card ejects itself randomly when i lock the screen (I think ejects triggers the soft reboot because I migrated the internal data and transfer all apps to sd card and somehow it affects the system too) example while im listening to music and I lock the screen then pause it using my headphone or when im not using it the device will soft reboot. (I also think that because i used vpn to install android pie update and installed the one with bugs) Tried factory reset and flash it back to v10.0.2.0 (Downloaded from Xiaomi official website) using fastboot and update to latest update but it didnt work. Pls Help me fix this.

You said you've migrated all the apps to the SD card which is formated as adoptable.
Did you try to move the apps back to internal memory to check if that's the issue?

Sorry to hear that. I personaly don't use adoptable storage so can't help more. Only thing that comes to mind is to try and clear the app data from apps that were on adoptable storage if moving back to internal memory.

Since the January update while charging the battery I get warnings that my SD card (formatted as portable storage) is corrupted. If I just reboot after the warning everything is fine again.

Do you have access to the data on the card while it's charging?
If you change USB options to e.g. MTP storage instead of charging, does it change anything?

Nope, after the corruption warning I can't access the SD card until I reboot and it only bugs when using the wall charger.

You could try to use a different charger (I know it's stupid but trying to eliminate all the small issues like that sometimes gives good results).
Waiting for another update might fix the issue if it's a ROM thing, naturaly if you want to wait.
Worst case scenario would be to try and rollback to a previous update (backup first).

I've had the same issue on both phones i bought. It randomly unmounts the adopted storage throughout the day. I've tried different cards but it's been an issue from the beginning and through every update. It seems like it doesn't have an issue as long as something is actively reading from the card, ie. music. However, I haven't tried clearing app data on the apps i moved to internal yet.

Wellp the february update did not fix this problem. Is there anyway to contact them to fix this problem for the next update?
