MicroSD card showing as empty until pop out and reinsert - Galaxy Tab Pro 12.2, 10.1, 8.4 Q&A, Help & Trouble

I have a Samsung Galaxy Tab Pro 12.2, SM-T900 stock non-rooted OS 4.4.2, and a Sony 64 U1 microSD.
At times I go to send an attachment and the file manager shows the card but it shows it as empty. I pop the card out, re-insert it and back it comes. Sometimes the card doesn't have the problem for weeks and other times it happens 2 or 3 times in a day.
I thought I might reformat it after copying everything off, but I know there are apps that store setting/data there and don't know if that will mess things up.
An issue anyone else has had? Any thoughts?

should be fine, first unmount the sdcard cleanly by going to settings - general - storage - unmount sdcard, then remove it - when you copy the data off make sure your pc can see hidden files since you will need the hidden folders if you have apps moved to the sdcard.
when you format the card it should be in exfat format (not fat32), since it's a sdxc card (64gb+)
if the problem persists then the sdcard probably went bad (happens all the time, I must of went through 3 64GB Sandisk ones already) the system is designed if the card gets an error reading or writing it will unmount / remount the card - it could also be temperature related too some sdcards also have a protection mechanism where it will switch it to read only mode making it impossible to write to it or format, if you are lucky it might have a good warranty and you can get it replaced hassle free.

I did check the card before posting and it is formatted exFAT. Also using an SD card adaptor put it in my PC and did a Chkdsk on it with the /f option to fix any problems and no errors were found.
Unless someone has something else to try later today I will copy everything off, put it back in the tablet, and under storage SD I'll Format it with Android.

Cannot take pics :unable to save file to sd card due to insufficient file permissions

Hi geeks
Problem when i try to take pictures.
Does anybody have a fix for that issue "unable to save file to sd card due to insufficient file permissions".
Formatting SD or rebooting doesn't seems to fix the problem indefinitely.
error message come back after a little while.
I don't want to hard reset unless it really fix the problem!
Is it a defective sd or a bug or else ?
Many thanks

HaHa, I have the same problem with taking Pics on my Desire too, I get "unable to save file to sd card due to insufficient file permissions"
I defragged my SD Card yesterday using Windows 7 defrag tool but I doubt it's damaged it long term. If I figure out a fix i'll let you know...
FIXED!
- Press Menu/Settings
- SD & Phone Storage
- Unmount SD Card
Turn off your phone then take out the SD Card. Replace the SD Card & Battery then reboot your phone. With any luck it should be working again, did the trick for me
I tried that. It works for a day or two. And then again the same issue. Any long term solutions? I am planning to send a query to HTC support. Let me see what they say.
Same problem with Evo 4G
I have an Evo 4G (from GoogleIO) and have been having the same issue. A reboot fixes it temporarily but it comes back in a day or two. Hoping HTC gives you some ideas.
It has happened to me , remove Ebuddy or any msn messenger and probably you'll be fine.
I used to get this occasionally with the 4GB card that was included with my Desire. Once I bought a new MicroSD card it stopped happening.
Same problem with Eris. I unmounted, now just formatted and still cannot take a photo. Argh
HTC aria sd card insufficient file permissions
All I did to fix this issue was reformat the SD card. In windows, go to computer management, disk management, right click on the SD card, it might be labeled as F: or E: drive, click format. I formatted mines as FAT. All done, I was now able to save pictures, and videos to my phone's SD.

If you format the fat32 and you have ext3, and it keeps happening, you'll need to remove the ext3 partition, format in fat32 the whole card. This will solve your problem permanently
Hi, I have an HTC HD2 which I recently upgraded it rom ver. 1.66.415.9. I used spb backup to get my main memory files. Somehow, in a way, I was able to get all of my files anfd programs with windows settings and registry using ROM upgrade mode without changing the rom version back to the old one. But the then when I took pictures then tried to open them in albums, they weren't saved. A probition sign (circle-backslash "no" sign) showed up. I tried to open it but an error shows up saying "unable to open this type of jpg file" and then the sign diappears, as if the image wasn't saved. I even tried saving a note file. After saving, I opened it but instead of showing the notes I wrote, symbol characters showed up as if the file was encrypted. After rebooting my mobile, the note file wasn't there. I still have enough storage space to save more files and pictures. Did anybody face the same problem that I did? Please help me and thank you in advance.

If you are on Windows machine, connect your HD2 via usb and mount your SD card. In Windows go to System Tools and Drive Manager. You should see your drive mounted as a removeable hard drive. It should be about the same size as your SD card- a 4GB card will show up as 3.7 gigs or so, a 16GB. as 15 gigs, etc.
Click on that drive and on the right side window it will tell you what kind of partition it is formatted with. You can also right-click on it to reformat it.
JUST MAKE SURE YOU ARE NOT ACCIDENTALLY FORMTTING AN EXTERNAL USB DRIVE OR HARD DRIVE

had the same problem and reboot fixed it. i thought you had to have the ext partition to do apps to sd on some of the roms. i use extended batteries and like my synister rom alot so i'd rather restart my phone occasionally to fix the issue. Usually i power down and pop in the fresh battery before heading out the door so it took a long time to notice the problem. Otherwise i'm too much of a noob to be much help but really is restarting your phone occasionally a huge deal.

[Q] Epic 4g Microsdhc issue and One Click Root & Recovery v2.5.5

Hi,
Please forgive me if this is a noob question. I recently developed an issue transferring files to the sd card. Using the usb storage method, after transfering 2 or 3 mp3s, the phone would shut off and reboot for no reason (This caused the Zeam launcher to crash apparently? for at least 15 tries)
I tried using the SD adapter, the transfer rate is extremely slow or to no transfer at all and causes windows explorer to crash or hang (tried at least 15x).
I figured my sd card was corrupted so I tried formatting the card. If I used the SD adapter, it would say the card is write-protected even though clearly, the locked was off. I even tried another SD-adapter to no avail.
Finally, using USB storage, I was able to format the SD card.
Since I mentioned earlier that the Zeam launcher crashed, (yes, I selected always use "zeam launcher" even after it crashed causing the error message to loop) I resetted the phone with the wipe data/factory rest option in clockworkmod (I'm using ViperRom 3.03).
I wasn't sure if the 1 click root (http://forum.xda-developers.com/showthread.php?t=770388) installed any folders into the sd card so I ran the 1 click root in windows just to make sure. After rebooting from the 1 click root, all the files that were previously formatted were back.
I guess I didn't read too clearly but
my questions is
1) how am I able to disable that backup function? I had a bunch of files (which I have no idea what they did) from when i first started playing with the phone and I want to start off fresh with just the files I need.
2) anyone have any idea why the sd card was unable to accept files through the SD adapter or USB storage method?
3) what to do when the launcher crashes (this happened to me 2x already where I lost all my data)
Thanks to anyone who can help. This will help me close some gaps in my limited Android/Epic 4g knowledge.
definitely something is weird. Using usb storage, I ran the scandisk to fix errors and some errors were found. I formatted to ntfs just for kicks and the sd card read blank and in properties the drive had nothing in use. I turned off usb storage, turned it back on and voila, all the files that weren't there are now back. It this a sign of a corrupted sd card or am I going crazy?
Which files/folders are you referring to? Because as soon as your phone mounts your sd card, it will write about 4 folders (I think) if they are not already there...
.android_secure
Android
DCIM
LOST.DIR
if I recall correctly. The other thing you can do is use your phone to format your card instead of doing it on a computer... go to 'Settings->SD card and phone storage->Unmount SD card' then after it is unmounted, use the 'Format SD card' option. If this doesn't work, then you may need a new sd card/phone.

[Q] SD Card Destroyed??

I picked up my phone looking to download a new ROM to it but then found that my ES File Explorer (given root permissions) was not able to view my external SD card via the mnt folder. At the same time, I was trying to back up my apps and such via Titanium Backup but it said that it couldn't backup anything because my card was full (it's default save location is my external card). It just said "Empty". I went to check my Settings to see if my card was somehow unmounted, but nope, it said it was still there. Even said that I had 11.27 GBs left out of 29 GB or whatever and gave me the usual options to Unmount and such. I pulled off my battery cover and the card was still there, so I assumed that the Android system might just need to sit for a while and cool off while off. Then I turned it back on to find that ES was still not able to view the contents of externalSDcard. So I went to my Root Browser and it too said that no files were there. I then went into my Settings and now it just says "Insert SD card".
I've had this happen before on other Android phones so I did what I normally do and hook it to my PC and reformat it. Windows found the device when I attached it via a SD card reader (the big fat kind like in your standard camera), it didn't want to format it. Windows brought up the prompt and said that it only could format 1GB so I knew Windows wouldn't be able to recognize it. I even tried formatting it via Command Prompt and typing "Format G:" and it too said there was only 1024MB to be formatted then went through trying to format and then said it failed.
I then tried pulling up Ubuntu's Disk Utility to format it. At first, Ubuntu wouldn't even correctly identify the device! Then I got the Disk Utility to recognize it and it couldn't even recognize how many GB/MB were originally on the card! Trying to format just brought up a message telling me that it couldn't do anything.
I had this happen a few times with my HTC Evo 4G OG but was able to format the card and put it back into my phone and have it work. Of course, the last time with my old 16GB card ended with it being destroyed much like this.
Please tell me that I can do something to fix this. Anything?!?!
This card is a 32GB Class 10 Patriot. This has happened before in my old HTC Evo 4G OG with a 16GB Class 4 SanDisk card. That card became unusable after a few times of this happening except I was able to fix it those times using the methods I tried above and allowing my phone to recognize the card again.

The second issue is that when I try to reboot it says usb brick and fix it before i can reboot,
but this has not fixed the card.
can somebody please help me with this issue as I do not want to purchase another card.
Can you at least read your sd card, preferably in a card reader to remove any phone element? If so back up the whole card to PC
Then I suggest a complete reformat of the sdcard using gparted live cd: a single FAT32 (on the left) and then maximum 2GB ext4 partition. Again do this in a card reader to remove any phone or driver issues.
Copy contents back to sdcard afterwards.
If none of this works then you may simply have a bad corrupted sdcard. Although it's not a great solution to buy a new one, make sure you stick to a reputable brand, even those are not that expensive nowadays.
No .. I have tried several times, but pc can not read it.
I do have the contents copied though.
any suggestions, as pc can not read card.

The card is Sandisk.
I can sometimes access the card on the pc using the usb, but not all the time
Well at least you have the data backed up, so nothing to lose except an sdcard.
- Are you using a card reader?
- Have you tried gparted and a card reader? This has the best chance of working.
If you can't read or see the card by any means, then not much else to suggest but a new card.
Can see it sometimes using usb connected to phone.
will try your suggestion shortly and let you know

MicroSD problem: corrupted message and unable to format + bootloop if SD is inserted

Hi everybody, I just wanted to share my experience with microSD card reader on my XT-1676 16GB/3GB RAM
When I bought it in May everything was fine but few days after the purchase it suddently came out with a problem I can't work out with: the microSD I had inserted and which was working quite fine was recognized as "corrupted", and I had to format it (and choose between external or internal storage) in order to get it working again. Point is: formatting keeps failing, no matter what I choose (external/internal) with this error when as external: "command '15 volume partition disk:179,64 public' failed with '400 15 Command failed" (numbers change sometimes), and by stucking at 30% when as internal. On top of this, if I keep any micoSD inserted (I've tried many of them) when the phone is off, then if I power it on it will bootloop, even if I boot into TWRP recovery. As soon as I remove the SD during bootloop, the phone boots. During the last months I've been searching for a solution of course, and I figured out that many other Lenovo users has my problem, but I didn't find any Moto G5 owner with my frustrating error.
After the NPP25.137-72 update (which didn't solve) I've unlocked my bootloader and tried many ROMs, but seems that my Moto G5 is just unable to deal with /extsd (ot whatever it's called) partition. Lastly, every single microSD I have tried in my phone and has been told "corrupted" by the MotoG5, works flawlessly instead when in other devices.
Do you think I have an "hardware disease"?
Thanks
The only thing I can suggest is if you put the sd card into a pc (you can get a cheap card reader if you dont have one) - and using something like minitool (or any other partition manager) delete all partitions one the sd card and create a new fat32 partition and format it
Only use the sd card as external storage and you can use the rescan media app (see app section) to find any missing files that the android media scanner couldn't find
if it keeps coming up corrupted when trying to mount the media scanner app wont work - but if it can mount the sd card but cant display the files the media scanner app should be able to display the files - of course if you have to delete and recreate the partition than any files you had on there will be lost

I always format my SD card via GParted before inserting it in the device. I am seriously afraid this is a HW problem, though.
