"SD card unexpectedly removed"

[ToddL]

I tried many things, nothing worked until I broke down and bought a Samsung SD card. That was 6 months ago, and haven't had that warning pop up once with the new card.

I bought a cheap microsd from ebay, it began to unexpected remove, and doing so always when I was compying or sending a bigger files, and sometimes it removes instantly after inserting card in. At the 2nd problem always helped puting card into another phone and back.
The first problem I never have solved, I would say that it's because of a cheap piece from ebay

I also received the same message, followed the forum advice of re formatting sd card (sandisk 32GB) and so far no more problems. I formatted it on my PC (UbuntuGnome 14.04) so far so good. Had to reinstall a few apps, but they were already backed up to sd card. I copied all data to PC prior to re formatting sd card.

Good luck to all, hope this helps.

I've been experiencing this issue since my galaxy s4. When I made the move to the HTC one m8 I used the same 32 gb SanDisk class 10 and the problem went away. I recently upgraded to the Galaxy note 4 with the same 32 gb card. And I'm getting this Damn error every time I open my gallery. I've done all the little tricks such as formatting the card with the phone etc and nothing. I find it absolutely ridiculous that Samsung hasn't address this on going issue that's been going on for years now. I've heard rumors thought if you buy their brand mirco sd cards there's no problems. Any truth to this?

Yes, after having many problems with the SanDisk cards, I've had the Samsung SD card for 1.5 years, no problems with it.

SOLVED by this workaround. Credit to XDA user sijie.

What failed:
1. Changing kernals and ROMs
2. twrp / goomanager / open recovery script
3. Setting SD card cache

What worked:
Thanks to the SD card monitor app, it was obvious that this problem only occurred when the screen was locked. It unmounted / remounted every ~3min, which drained the battery really fast. So I suspect it's caused by the phone's sleeping mode. After trying out a few apps, Wake Lock app did the job for me. Download the app from Google Play and set it to PARTIAL_WAKE_LOCK to keep the CPU awake constantly. Of course it consumes battery too, but way better than the SD card did before. Now the card never gets ejected and the battery can last more than 10hrs in normal usage.

This worked for me!! Very minimal impact on battery. This is clearly a power saving issue compatibility with certain SD cards.

S2x T989 (koodo)
Android 4.1.2
32GB adata class 4 SD

Was mounting and unmounting dozens to hundreds of times/day, but never when plugged in (e.g. charging overnight). Did not seem to be a physical problem with SD slot or card. Formatting SD would temporarily help, but it would come back. Had tried disabling various power saving, various ways of formatting in computer or phone or phone via computer, etc. Nothing worked until now.

Wake Lock app with Partial_Wake_Lock seems to have solved issue!

followed ur more than 2 year old tip and its been more than 24hrs since SD being unmounted. saved me from getting a new phone.

my phone was a replacement phone from an RMAed unit from getting the same issue. now it's over warranty and i can't get anymore replacement.

i had to endure nonsense like being told my SD card is fake or is damaged when i post issue on other forums.

couldn't find the OP sijie, so thank tqvm

I've had a Samsung 64 gig in my galaxy s4 for 6 months and nothing but several unexpected removals a day. It's ridiculous.
