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

i have a blue angel/sprint ppc 6600. almost every other night between the time i go to be and the time i wake up the sd card gets erased all by itself? i wake up in the morning and everything on it is gone? i make sure all the programs are closed when i put it down for the night. i cant figure it out? any ideas?
i have about 6 programs and some files on the 1 gig sandisk sd card. i have replaced the sd card and the problem continues.
thanks.
This worked for me - I don't know if this will work for you
I formatted my 512mb sdcard took it to fat32
I then ran scandisk and defrag on the card - there were lots of errors
after fixing that
I then reran the scandisk and defrag until all the errors were gone
I now back up my SD card every other day to my desktops Hard Drive
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

Ok
Have a Galaxy note 10.1 2014
No mods not rooted
I have a 64GB micro sd XC SanDisk ultra card.
It sees it and i can put files on it and read those files, but eventually i cant write to it anymore and then it says the sd card is empty but i see it still has the same amount of space used but cant see any files, didnt see any sd removed statements or anything. Still can see the files on my computer with a direct connection to the sd card but not through the tablet.
Thoughts?
I also sometimes get an "unfortunately, gallery has stopped" pop up box
I had the exact same problem, even if I formatted it lol. Had to be returned as defective. There is a tool on the sandisk website that will format the card in a specific way. Would not do mine though as goosed. Good way though to tell if your card is knackered.
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

My SD card is always corrupted. I tried using different SD cards even i bought a brand new SD card and it is still giving me issues . I did a factory reset and still does the same. Anyone else with the same issue?
What's the capacity and speed of your SD card? How are you formatting the SD card? Do you use it preformatted or format using the phone? The reason I'm asking is it seems to me that Sony has set a too low timeout values for formatting and mounting the SD card. So if your card is very big or not fast enough, the phone would timeout too early when formatting and/or mounting the SD card on boot, thus causing it to be detected as corrupted. At least that is how it seems on my phone.
perhaps have reset your phone from previous backup ? if this is the problem already happened to me ,
They are both high speed cards 10 cards Toshiba and Samsung to be more specific. When i format them they seem to kinda work at the beginning i even managed to copy a video file but after a phone restart it gets corrupted .
MM updated through xperia companion here, seems to be working normally with the old microsd card
Hi Team,
I also have the same issue here, whenever I move applications to SD card (Samsung Class 10), the application stops working and I have to
reboot the phone to have it running again. Though it happens only... when phone is from Doze mode, turned on the screen with power button, and after turning on mobile data and run the app like COC or Viber it crashes. Now this happens only, if my application is in SD, if it's on the phone it's working fine.
Hello everyone.
I also have this problem. I have a Sandisk ultra (red and grey) 32gb class 10 sd card, and my M5 on 6.0 cannot format it at all, first it says it's corrupted and I have to fix it, then the format screen is stuck on 20% and after a while it says the card cannot be formatted. The card isn't counterfeit, and it worked flawlessly in my m4. It was replaced under warranty because I presumed it became faulty, and I still have the same problem. There is no problem with it on my PC. Also the phone freezes when the card is removed and I have to turn it off with a paperclip on the small "off" button.
You have sd card restrictions on 6.0, so you can use it for media, can't move apps... I've got Transcend sd card class 10, no problem at all.
I know about the SD card restrictions but my card was working fine in 5.1 for storing photos and videos taken by the camera applications . Now i have tested even more cards and they all have the same behavior. Even with an 4GB and 8 GB Toshiba cards and an old 2GB transcend card.
tonev, how are you formatting the card?
On the phone it self. Also tried to format it on my laptop , Same result. Sometimes it works fine and after i restart my phone it gets corrupted again
any news or fix here? seems we're stuck with this sd behavior? can't really move apps to sd card?

Is it correct to assume that you restart the phone only using the default power menu and not using any third party interface?
Another thing, it is not advisable to format the SD card using Window's Format function. It is possible to damage the SD card this way. The safest way to format an SD card in Windows is by downloading and using the SDFormatter utility. I don't know if formatting you card in Windows is what has caused your SD card to be corrupted, but it is something to be considered.
Yes i do restart the phone only by using the default power button. menu. And none of my cards are corrupted because they work fine on other devices. As i said before a brand new never used genuine samsung SD card does not work on the phone.
