Strange SD Card behavior - Android Q&A, Help & Troubleshooting

Hi all,
I really need some help/advice/etc. I've switched from my 32gb SD-Card to a 64gb, well just stuff people normally do. Unfortunately my phone (Lenovo K50-t5) is now forcing me to decide between portable and internal storage mode. I've tried both, but non of them works the way I want them to work. Unfortunately I've formated my 32gb SD and am unable to make it work again (also being forced to chose one of these modes). I've tried several ROMs by now and all have the same behavior.
Does anyone have an idea how to use FAT, exFAT formatted SD on Android MM?

missing files on micro SDHC after transfer

Hi, i have my HTC hero rooted with the last Villainrom 12.0.0, i recently bought a new micro sd card 32gb and i dont know why but after i transfer data to my sd card i can see it, taste it, use it with no problems, but when i put the sd card into my phone some files get missing, i dont know why, but they just dissapear, may get into some kind of trash folder hidden into the card, but they are just gone...
i tried eather mounting the sd from my phone trough USB and retrieving the card from the phone and pluging it into the sd card reader in my pc, it doesnt matter, the problem stays.
i thougt may be it was some problem with the partition, i had the partition to use apps2sd, ext3 and all the crap, but the issue was still there, then i formatted in my pc fat32, still the problem, and finally formatted trough my phone fat32 and the problem persists, i dont know if maybe some software on my phone is making this happen or anything...
i dont know what to think, i know my sd card is ok becouse i used it filled with data and had no problems before...
please help me.... im gonna cry
I have exactly the same problem with my HD2... trying to upgrade from 8bg micro SD to 2gb micro SD.... everything copies across (or so it seems) however all the files in the 'program files' folder haven't come across, nor has my TOMTOM gps folder files..... ?
I've tried everything I can think of, why can I not copy card to card via my PC.... I'm sure it was simple when I changed from 2gb to 8gb cards.
Any help very much appreciated.

32Gb Class 4 microSDHC - Phone unstable! Please help!

Hi all, I bought yesterday 32Gb Kingston Class 4 microSDHC card. Now my phone is very unstable with this memory. I mean, sometimes it can't mount it, sometimes it shows its empty, formatting almost hangs phone, some apps hang phone (apps on sd). Looks like the phone doesn't want to eat this big memory too well.
I already tried soft reset, and dalvik cache deleting. Didn't help.
microSD is formatted into Fat32 and 32Kb clusters in windows with HP Formatting tool.
If I try to reformat with phone, nothing seems to happen....
It can work perfectly for a 20min, but if I try to turn many apps on and off, it will reboot. After what it doesn't see apps on SD card. wtf? But after complete reboot, it'll work again for a some time.
I have 2.2 Android from elelinux.
If I use my old 2Gb card, everything works just great.
Any ideas?
P.S
What does this recovery mode SD card formatting? Maybe I should try this one?
I have ClockworkMod Recovery 2.5.0.7. There are some interesting options like..
What ARE these?
1. Format Cache
2. Format SD card
3. Format sd-ext
4. Wipe Cache Partition
P.P.S LOL I can't turn off phone. It is rebooting always. Wtf?

According to the HTC website, our Hero's should support 32GB.
But that's as far as my knowledge on your issue goes. Just ordered a 32GB Class 4 SanDisk card myself, so when its delivered (hopefully Friday) I'll let you know how it performs.
Just an update for you, mine came in the post yesterday and it seems to work fine with my phone. Loaded it with 20gb of music and it runs fine.
Yep should run fine with 32gb sd cart
i'm having many of the same issues with my 32gb. had a 16gb before, and all was well.
now the phone randomly goes back to charge only when i have it plugged into PC as disk drive. i'm having trouble making backups in recovery too as it says its randomly unreadable in the middle of backing up. also, and seemingly most frustrating, is it is refusing to actually transfer files from PC to SD. i will plug in as disk drive and move all files without issue. however, when i eject disk drive and switch back to charge only mode (or simply unplug), none of the files have actually been moved to my device. they are simply missing entirely when i open any file manager.
i've tried everything. formatting on device, formatting through W7 (quick and full), and formatting through the official sdcard.org tool. nothing helps.
Try this
If u have a linux PC, u will know about gparted, I guess.
Do this: boot to ur favourite linux distro. plug the sd card to ur pc using a card reader. open gparted. click tools and then click new partition table. it will wipe everything from the card.
once done, just setup the partitions as u want for fat, ext or whatever. i was having a htc tattoo troubling me with a 16GB card but now its okay.

[Q] sd card issue

I tried 3 different SD cards from 3 different cameras, none worked on my tablet, all worked on vaio laptop. Is my port damaged or am I missing something here?
make sure the format is FAT32
hmm..I'm not in the same country as my laptop now, I'll check when back home
I am thinking of buying an S1 but I read a comments on another sitre about the SD card that indicates you cannot move apps to the card (as you can with most other android devices).
Is this true? If so would it better to get a 32GB S1?
Try to plug the camera in via the USB host function, should work.
Sometimes I have to reboot the device with the sd-card pre inserted before it will recognize it. Maybe that might work?
On off suggestion didn't work...will check if fat 32 tomorrow
I bought a SDXC 128GB card for my tablet. I formated it with FAT32 and it works like a charm.
Happened to me too... fat32 formatted and all, still wouldnt detect it. I had to put it in and out until i finally saw the message on screen about the sd card being connected =/

partition SD card for android/win10 dual boot tab?

well, i recently bought the Cube i10 with android & windows 10 pro as dual boot OS.
Yet i'm satisfied with the device (even though battery drains pretty quick when switching from windows to android and back to win).
The main "problem" is that android "only" has 2.91gb space.
Well i don't know yet how these apps2sd work, yet i'm fine with 411mb left, but there may come a time where i may need more space (from SD, if even possible).
I've read around that it's possible to format an microSD card on windows. I've also tried around (using "MiniTool Partition Wizard free" for PC/Win10). I managed to split my (now for testing 2gb SD in 2x ~1gb.
I formatted both as FAT32. In windows, the 1GB is showing, yet not on android. I get the message that, if i remove the SD card, an sd card was removed, yet nothing shows in the (stock) file explorer or settings.
I think my major "problem" i'm overseeing is simply a filesystem or primary/secondary/whatever error.
Any advice from experienced users?

Access SD-Card (formatted as internal storage) via USB or Filebrowser App?

Hi P9000 users!
I had now time to test some stuff with my P9000. One question: I inserted a Sandisk 128 GB SDXC Card (UHS) and formatted as internal Storage (want to move apps). Worked fine for the Phone and i was able to move apps to the SD. But after connecting Phone to USB (via MTP & unlocked phone) it only shows 32 GB internal SD. Also via File Explorer app on the phone i cannot find the external SD or mountpoint....
Anyone with same issue? I also changed connection-type to USB and then my OS (Win 10) does not open phone file system at all.
thx and br

We did an article about the SD card memory management in Marshmallow a while ago on the XDA portal that explains this, I'd suggest googling for it as I can't remember the title.
Edit: Something to do with the SD card being formatted as Ext4 (linux file system standard these days) and Windows not supporting Ext4 filesystems.
Thx for reply, so i am afraid its related to Android 6 default behaviour. So if SD is formatted as internal storage you cannot access via USB from PC or managing files on it via file browser app? Thats really disappointing for me since it then switches SD card to enhanced app storage only, useless for image, videos, music etc. Of course i can format as portable SD, but then no movement of apps are possible (via root its maybe the only option).
In SD portable mode, i also had issue that SD cards randomly disconnects and one time it even needed to be reformatted. Have read about that in another thread, that this is related to physical sd mount... will see to fix this with some tape :/ (gives me not a good feeling here)

Update: checked some forums and blogs, seems not to be android 6 default behavior that you completely cannot access the files on adopted SD-card anymore. after adopting as internal storage... anyone could also reproduce this? I will try doing factory reset with SD-Card inserted..
