[Q] SD card deleted

This may be in the wrong forum so mods please feel free to move it.
I am at work and needed some images from my Nexus's camera that were stored on the microsd card. I didn't have my cable with me so I removed the card from teh phone and inserted it in the card reader port on my laptop to copy the images. When I opened the sd card I noticed that all folders belonging to android were gone. All downloads DCIM everything. Most files that are just on the sd card without a directory are untouched. I put the card back in my phone to check for sure and everything is gone.
I'm currently using a recovery tool to try to get back my images and videos.... Hopefully I don't lose too much.
I have no idea why this would happen. Does anyone have a clue what would cause this? I have never had any trouble using a microsd card from a phone in my computer before.
Any clue how/why this happened and how to prevent it in the future?
Thanks!

Bad dismount. You probably pulled the battery without shutting down the phone first.

Did you try putting it back into the N1 to confirm lost files/folders, before further risk/modification from your computer?

Says so right in his post.

Can no longer write to external SD (4.3)

Sometime after I installed safestrap and a second rom, I lost the ability to write or delete from my external SD card. It may have something to do with SAFESTRAP, or possibly an app called SDFix: KitKat Writable MicrosSD which I installed and may have ran in preparation for any type of KitKat update. Anyone have any ideas of what I may have done?
edit for more info : The weird thing is, it lets me go through the motions to delete a movie file with say ES File Explorer, but when I reboot, the file is still there and I am able to watch the same exact file I thought I deleted. Also, if I set my camera to write external, it seems like it works, but when I reboot, the files aren't there anymore. Luckily the few pictures I tried taking like that were uploaded to my dropbox before I reboot..... Also, if I create a new folder and paste a file into there, the folder won't be there when I reboot. Also, it seems like my titanium backup files aren't updating, they all seem to be dated February 28 and they won't update even though it goes through the entire backup process!

Have you tried taking the card out and seeing if it works properly on a computer?

That is a good idea. I'll try once my co-worker comes back from lunch so I can borrow their microsd-usb adapter. The weird thing is, it lets me go through the motions to delete a movie file with say ES File Explorer, but when I reboot, the file is still there. I am able to watch the same exact file I thought I deleted. Also, if I set my camera to write external, it seems like it works, but when I reboot, the files aren't there anymore.

The card is an 64GB Sandisk, and the computer won't recognize it, I believe because of the way it is formatted. When I get home, I will try to connect via USB 3.0 and see if I can dump everything to my PC and go from there....

Your computer should still recognize it though.

uhh ohh, its a VDI virtual system, and it says this card needs to be formatted before windows can recognize it....

I am copying everything over to my PC over USB. I will try the card in a card reader to see what can be done. If I format it, and if it works after format, should I have confidence that the card won't crap out on me in the future¿???

I am finally able to format it using a slow format in Windows 7, lets see if it works...
Nope, still broken with all previous files in tact.

I'm having the exact same issue and I bet others are too. At first I thought it was something to do with an ESexplorer update since I never happened before it, but I've deleted ES and tried many other file managers/explorers and still have it happen. Someone has to know how to fix this.

I had the same issue with the same card. After a lot of research I found that my SD card had somehow become locked...I know...WHAT? My sd card is looked with no way to unlock it. I can view files on it but i cannot add files or delete from the card.
I emailed Sandisk asking them if they had a solution but I never heard back from them
I have tried every solution that I have found and none have worked...

I've gone through 6 San disk 64gb class 10 cards between my Note 2 and Note 3 with my last cropping out 2 weeks ago. San disk will replace your card and tell you to contact the phone manufacturer. I did that contacted Samsung...at 1st I got the run around but I was persistent and got a hold of a good tech support agent. Samsung phones have issues writing info to the 64gb class 10 cards. They are aware of the issue and are working on a fix as of 2-3months ago. He told me the will work fine. He said they don't recommend over 32gb and a class 4 card because of the stability issues of files being corrupted on class 10s particularly 64gb 1s. Funny thing is i called San Disk back and told them what i was told and asked for a 32gb lower class and he told me i could buy it buy they could only replace it with the same one i had. Good luck!

You know this is not the first time that I've heard of this. I actually had a 10s 32Gig SanDisk micro that I ended up losing because of this problem with my Galaxy S3. I got to work one day and set my phone down on the desk and it just seeming stopped working. I don't know what it is with the 10 series cards but it seems like they all have some kind of problem.

Thanks everyone for all the info. I guess I'll have to get another card and I'm going to be sure it's NOT another SanDisk.

Apps disappear after reboot?

I have a strange problem with my note3 n9005 that is running omega v.16
Lately when I install an app from play store it works great until I reboot the device.. After I reboot the app I just installed is gone and I have to install it again..
My old apps that I have installed before this problem started occurring are just fine, and does not disappear after a reboot.
Does anyone know why this is happening, and if there is a way to fix it?
Thanks in advance

Are your apps installed on your external SD card?

Good question, I have a 64gb SanDisk card in the phone, but as far as I know I never choose to install anything on the external card.. Where and how do I check that?
Thanks in advance

I just checked, and you where right.. Some apps seems to automatically install on the external SD card, I moved it to device storage and it was still there after a reboot..
Many thanks my friend.
Now that leads me to my next question..
Sense many apps are installed to external SD and seems to work just fine even after a reboot, why doesn't any new apps stay there anymore?
I don't remember changing anything..
Is there a way to make it work again?
Thanks again

To be honest with you I'm not sure. I do know android has made some changes in KitKat in regards to the external SD card not being able to write/read for 3rd party apps. There was a fix for this somewhere on XDA. Now the question is, if this is related? Couldn't tell you. Only advice I can give is, leave your apps installed in your internal memory. Keep everything else for your external SD. Glad I could help!!

I appreciate your help, and perhaps someone else can shed some light on this.. But for now I will have to check and manually move the apps that installs to external SD..
Again many thanks!

Yo. I may shed some light in this situation.
Get a new external SD card - 'tis what I did.
I had this 64GB SanDisk UHS-1 Class 10 - exactly what you have: http://www.sandisk.com/products/memory-cards/microsd/ultra-class10-for-android/
One day when I took out my MicroSD from my phone and put it back in. I thought everything was fine. During transfer it transferred things to my computer, but then it kept freezing up. My ROM file (250mb) was transferred somehow into my MicroSD along with the Google Apps zip. When I turned off my phone, preparing the ROM flash, I only saw my ROM file and not my Google Apps file. I thought "that was strange" and I did it again, by deleting both files just in case of MD5 mismatch. This time both files confirmed inside the MicroSD, I rebooted. No Gapps showed but my ROM showed, so I tried to install it (note I deleted this file already) and it said ERROR. I plugged it back into my computer, Google Apps was not there, but my other files like photos, music, app data still remained. One peculiar file popped up, was my ROM file. It was 20kb. I deleted it. Rebooted my phone, plugged it in. It appeared again.
Seems like my microSD entered a stage of read-only but it isn't actually read-only. Like it doesn't retain any information AT ALL. My MicroSD can't be touched, I tried deleting 13gb. Windows showed the data actually getting deleted with the bar (and it fluctuates in data I/O speeds!). Unplugged. Rebooted. Plugged back in. 13gb worth of files still there, in tact. Like a visual storage to fool people you can delete files but in fact you can't.
I tried it on my Note 1 (FAIL), Note 3 (FAIL). The only way I could read the extSD was to plug it in a microSD adapter and transfer files out of it. At least Sandisk thought of a failsafe read-only phase to back up files. Instead of breaking down completely.

You are absolutely right.. I checked the card buy putting it in my computer, and it was as you said in a read only state..
I was able to copy my things from the card, but I could not put anything on it.. I could not even delete anything or format it!
So I went to the store where I purchased it, and now I have a brand new Samsung UHS-I 64 GB.. Hopefully this one will last me longer.
Buy the way, it turned out that I purchased the card on July 17 last year, so had I been waiting for just 6 more days, I would not have been able to have it replaced.. So I owe you many thanks.

I'm using a Samsung card at the moment as well, it's quite good too.. The Samsung PRO UHS-1 64GB and it has yet to break down.. [emoji4]
Glad I helped!! If you need anything else don't hesitate to ask!

1 year warranty ?
AFAIK it is a lifetime warranty if from sandisk. hehehe. I might be wrong.
but the Samsung SD card is good. I have it, and works well.
The 64gb sandisk yes got problem. I have it as well with the problem

SD Card Access Denied Post 5.1.1 Update?

Anyone else having SD card issues after the update?
Since the update my photos are saving to the phone's internal memory and if I change camera to save to the SD it stays until I take a photo, then it says there was a problem saving to the SD and writes to the phone again.
Using FX I can see the "Media Card" but when I click on it it says "Access Was Denied" however I can use System/ and see the SD Card folder and access it that way.
If I unmount and remount the SD card in Settings it works again for a short while both for accessing and saving photos to and then goes back to being seen but not able to be written to for photos along with looking at my gallery and seeing none of the photos saved to it.
I am going to back it up here to be safe but do I need to do a full format of it or has anyone had similar issues and fixed it?

Did you do the edit to platform.xml I got that when trying to back up TB Try flashing this then see if it helped, this is for a 910W8 but should work on any N4

Thanks mate.
I assume that is for rooted phones, yeah?
Mine is stock, not rooted.

I think it is just a bunk SD card, ah well time to warranty it with ADATA.

The zip I posted is flashable but it could be the card I had the same problem. I did a clean through diskpart on windows

Yeah it is really weird.
If I manually delete the info on the card it appears gone but when I go to format it, all that info comes back.
I did the regedit and diskpart trick and neither worked.
ADATA told me to download the SD Card Formatting exe and it tells me it is write protected when it clearly isn't.
Hence why it is not accessible on my phone and cannot be written to...no clue how to reverse it or why it happened in the 1st place.

I can't write to my card after jumping to 5.1.

Suddenly Lost Ability to Write to SD Card

I have a very strange thing that has just started occurred with my wife's Note 4. It appears that all apps have lost write-access to the SD card.
I first noticed the problem with the camera app. The camera app was configured to write to external storage but when a picture is taken, it says "Unable to save file to SD card. Default storage has been changed to device memory."
The Gallery app is also not able to write to the SD card (cannot create a new album) or move files to an existing album on the card.
Solid Explorer cannot create a new folder on the card.
I've tried to clear app settings for the camera and Solid Explorer. But even after setting everything back up, I still get the same results.
I'm running stock v6.0.1 (EPJ2) rooted. Also, my (seemingly identical) Note 4 does not display any of this behavior. No changes other than normal application updates.
Any ideas what might be going on?

I've had this happen when an SD Card gets corrupted - you can still view and access the files that are already on the card, but you can no longer write to it.
Try the card in a PC and see if that can write to it - if not then your card is likely permanently damaged. I had 3 Sandisk 64Gb cards go like this in two different devices. Tried reformatting them every which way, but nothing would make them writeable again. Have used Samsung cards ever since and never had a failure yet.

Just restart your phone

There are 3 possible solutions:
Using MS Windows PC
Using Linux PC
Using TWRP Recovery with a proper BusyBox
Let me know which one do you choose & I will explain how.

You nailed it. My card was a 128 GB SanDisk Ultra. Pulled it from the phone and my laptop couldn't write to it either. Copied everything off and copied it back to a new card and there you go.
Grrrr...$^%**# SanDisk.
Out of curiosity, what Samsung line did you end up choosing? I think the EVO+ will be sufficient for me but wondering what you ended up using.

Glad you got it sorted! I've been using a Samsung PRO 64Gb - this is the 128Gb version on Amazon UK:
https://www.amazon.co.uk/dp/B01CRZCLAM
I think the newer version of it is this one:
https://www.amazon.co.uk/dp/B019QO1Q4O
But you're right - the EVO+ is probably sufficient. It wasn't available when I was purchasing:
