I'm having the same errors .Same sd card but on a N7105.Could it be that these cards are not compatible with the Galaxy notes and the sg3 because I have seen same reports on other forums?A lot of them! I also read on another forum that the cards made before December were presenting with these errors .

Go physical
My Samsung Galaxy note 2 showed same error. But when I used sd card on my PC I could see all contents. I tried several SD cards, installing apps, changing firmware and always same result. I almost return my cellphone to seller. BUT I remembered that on PC, dirt makes some noise and generates annoying behaviors.
SO I decided to go physical.
I turned off my device
I got off battery door, battery and sd card
I used contact cleaner generously on sd reader.
I waited for about 5 minutes.
I put back sd card, battery and battery door
I turned on my device
Bingo!! My Sd card is back!!!!
I hope this can help you...

Hello, I am having the same problem.
Since yesterday after rebooting my phone, I am getting "damaged sd card". After removing the card and putting it back in, it changed to "Blank SD card or has unsupported filesystem".
Cleaning the contacts didn't help.
Any more advices on this topic? I don't have a card reader for micro sd cards nearby. Is there a way to fix the sd card using adb / filesystem / shell tools?
I have some data on the card I didn't back up yet and don't want to loose.

When SD card get corrupted, you need a PC and a SD card reader. Connect SD card, open command prompt, type “chkdsk /f /X <driver letter>:”.
If this doesn’t fix sd card you need to replace it.

All right, I bought a card reader and tried the chkdsk thing.
To my big surprise, chkdsk told me that the sd card is RAW type and therefore not usable with chkdsk.
How's that even possible? How can a SD card simply change it's type?
Can I reverse it somehow and recover the partion table? I really don't want to loose the cards content.
Any more advices on this?

[Q] Problems with SanDisk MicroSDHC 64GB card

Hi this is my first time posting a question on here so I'm hoping I'm doing this correctly
I recently received a SanDisk Ultra 64GB MicroSDHC card to use in my AT&T Note II phone. When I inserted the external SD card into my phone, everything mounted correctly and functioned right. However, when I tried to transfer my pictures and music into to the external SD card from my internal SD card using the stock app My Files, it would say that everything moved to my external SD card, but when I checked it, nothing was in the external SD card and the files that i had moved from my internal SD card were gone. So I backed up all my files from the internal SD card to my laptop to make sure I don't lose files again.
Afterwards I tried all of these methods to get files to properly into the external SD card:
I tried connected the external SD card directly to my laptop using an adapter and moved the files there
I tried moving files to the external SD card while it was in my phone
I also tried using KIES and KIES Air to move files into my external SD card
The first two methods didn't even have files show in the external SD card. The third method, using KIES and KIES air had files in the external SD card but they were corrupted where I can open my picture and it's a icon of a man of some kind and my music files just wouldn't play.
So I just factor reset my phone hoping that this would fix this problem and I haven't tried moving files yet. I'm hoping that perhaps it was an app that was conflicting with the external SD card.
I know that my external SD card is not fake because it came in a legitimate package and I also ran a software (that I can't remember the name of) that puts in data in the external SD card until it fills up and reads the data to see how much actually went in.
Could anybody tell me what the problem is and how I can fix it? I can't go back to the store and exchange it because it was a gift and there's no receipt. Thank you so much for your help.

well seee if it works on other phone if not then sent it back to sandisk service center they dont need any proof of purchase just the sd card packet pic will do as proof as it comes with lifetime warranty , just sent them a mail and report if its faulty and they will ask u to send the sd card back to sandisk center and they will send u a new sd card :good:
if they ask for a sd card no just chk your sd card back it written over there and not on the package as the org number they need is available in sd card back

SD card problem. does not work and mount. HELP Please

Dear readers,
I hope you all fine.
Just bought LG G3. Shifted from S5. Facing problem of SD card not being shown in the setting> storage and not even the file manager.
When I plug in the sd card it shows a notification in the phone, "SD card inserted". However, after showing this message it does not show in Storage (setting) and file manager. Meanwhile, the sd card perfectly works in S5 even I plug it again.
Card: SanDisk 64GB xtreme series card.
Please tell me the solution to it. I am really worried.

First off, it might be a bootleg, I had the same problem. But, since you said you used it in your S5 and it worked, it's probably not.
The G3 might not be reading its contents or able to mount it properly, it senses it in the slot but can't or won't read it.
You can try backing up and copying your SD card's contents onto a PC. Then quick format it on your PC and then insert into in the G3, go to Settings then Storage and then, if it's mounted, choose Erase SD card.
After doing that, it should be able to mount the card and read/write to it. Then you can copy your files over to the SD card.
I noticed what might cause it not to be read is the Android and Data folders on the SD card (carried over and written by your other phone). I'm not sure if the G3 reads those and see other system files/configs and decides to ignore it or not.

i had the same problem. could never get an sdcard to mount, so i had to return the phone. my new one read the sdcard (same one) just fine. luckily, when i returned it, the VZW person didn't know to check for root... lol

Same issue for me but sd card was pefectly working since few hours...
Will try a backup and erase sd card

My SD Card died. I tried it several devices and it was "Dead Jim". Just got my replacement today from Amazon 17.99 for Samsung 32gb micro SD Card.

Can't remove android secure folder from sd

I have an non rooted, official Tab Pro 12.2 on 5.1.1. with an 64Gb sandisk Ultra SDXC micro usb card. I use the sd for movies on holidays. A few weeks ago i suddenly couldn't delete or write any files anymore. Not even format the card in the Tab, on Windows Xp, Windows 10, or even Linux Mint. In other tablets or phones i get the message that the card is empty, but can't be formatted. When i take a picture, the image is stored on the sd, so it isn't broken. I just can't remove it anymore.
I tried several programs for formatting sd cards, but i get the message that the card is write protected.
There is an folder named .android_secure and it can't be removed. I googled and found out that this is folder is created by app2sd, but i never used this app. Also i never moved apps to the sd card, so i don't understand how this folder is created. By the way, the date of the folder is 1-1-1970. Very strange.
It's very easy to buy a new sd card, but what if this happens again and ruin my next sd?
Has anyone had this problem and perhaps has a solution.

When the sdcard goes read-only the card detected a major fault with the card and a protection mechanism will switch the card to read-only mode so you can get data off (hopefully), unfortunately the card is toast there is no way to revert the read-only/write protect mode, Sandisk has lifetime / 10 year warranty on most sdcards so just contact their support and they will ask for the serial number on the back of the card (use a camera or magnifier glass to read it), do the rma form and send it to them and they will send back a better brand new card usually a good model, if you have valuable data on the card you can snap the card in-half (since it is read-only you can't erase it), just make sure to note it with support ..
I have been through two sandisk cards (both 64gb), one went poof dead, then the other did what yours is doing can't delete/write/format but you can see all the files - sandisk replaced the card twice no issues, the last card they send it working great no issues.

Thanks for your advice!
I mailed Sandisk and they will sent me a new micro sd card. They know about the problem with some of there micro sd cards, so there was no problem with that at all.

Worth a try.?
This has happened to me several times on different occasions.... typically after I have deleted all the extra and hidden files and folders my phone apparently likes putting on my SD cards. When I get that message, I will right click C: drive, select properties, go to Hardware tab, highlight the storage device, then run the disk check on the tools tab. 9 out of 10 times it will scan and fix errors on the disk... when it does not.. I redo the whole process.. . lather... rinse... repeat

Internal memory formatted SD card issues

I've an Samsung evo+ 256GB SD card formatted as internal storage in my HTC 10 for almost 2 years now.
2 months ago I decided to upgrade to a Samsung evo+ 256GB v2, with slightly better speeds. I simply cloned the old SD to the new one.
Everything was always fine, worked great till yesterday.
I had some weird stutters while playing music and then I noticed the UI was also getting stutterish.
Went to bed, charged my phone as I usually do. When I woke up and checked my mail the phone just froze and rebooted.
After reboot the phone told me the SD card was missing
I decided to shut down the phone and examine the SD card but the phone just got stuck shutting down, I had to force reboot and shutdown again.
I tested the SD by a full byte by byte read in Western Digital diagnostic tool for harddrives to see if my SD was broken, but it was fine, no errors.
I popped the SD back in my phone, started and the SD mounted fine, no issues so far.
Could the file system be corrupt? If it is, how do I fix it?
I could try and move the data to an external drive and reformat the SD, I've a USB 3 OTG cable. But I'm not sure how to do that either.
Will Android move the data for me automatically when removing the SD card as internal storage?

Stutters continued today unfortunately, especially when doing a SD benchmark.
I decided to use clonezilla and do a clone of the card to another one to see if that improves anything.
On the old SD I had 72MB/s read and 20MB/s write according to A1 SD bench
Internal storage 225MB/s read and 41MB/s write
On the cloned SD I have 74MB/s read and 19MB/s write
The difference is that the cloned SD is a Samsung evo+ 256GB v1 and the old one a Samsung evo+ 256GB v2
I don't get it though, doing a benchmark on a PC shows 90MB/s read and 80MB/s write.

I advice you to check media files. I had lived same problem. I found solution by chance . I attached sd card to my notebook to backup dcim and music folder. While copying the files, suddenly copy process stopped on a not special file. I removed the sd, re attached and deleted that file before continue to copy. When copying finished, i attached the sd card to phone... Whola... Without formatting or doing nothing extra the card started to work as expected
