[Q] Suddenly can't write to or delete from external SD - AT&T Samsung Galaxy Note 4

Not sure if my kid downloaded an app or somehow set something but I'm finding that I can't write to or delete from my external SD. Doe anybody know of an app that could cause this? Not rooted of course.
I tried unmounting and remounting, removing and replacing. Even when connected to a PC through USB I can't delete. If I remove the SD card and use a USB SD dongle directly in the PC I can then delete files.
Thanks

It means your SD card is dying. Back up your files and get a new one.
Mine is doing the same.

I've had this myself a few times.

Invest in a quality SD card. Watch out for the fakes.

Maybe you encrypted your data OR check your SD card with H2testw for bad sectors.

Can you help with micro SD card

I was wondering if another Desire user could help me out. I had a bit of a problem with my phone and had to switch it off and remove my micro sd card, but when I plugged it into my computer with an adapter there was no useful information on it for me to get back. This either means that this is standard and the micro sd card can only be read properly when the sd card is in the Desire and then plugged in. Or that my sd card has an error.
Could someone please help with this and let me know what files they can see when they put their micro sd card into their computer directly.
The picture is what I see.
Run Checkdisk (chkdsk) then file restoring software, to recover your files.
Then Re-format the card. Happened to me once, everything got meesed up. Re-format helped.

Checkdisk isnt a recovery software, but I ran it already, and I tried the recovery program but I cant seem to be recovering anything but more useless information, I dont know if the data is lost or if its still on the card but only readable through the desire itself.
Can someone please do what I said in my original post and let me know what they can see with just the micro sd card in the computer
Thanks
CHKDSK is scans for harddrive damage and it DOES recover the files, but with the .chk extension.
These are the files on my SD:
Uploaded with ImageShack.us
If thats the case then thanks for letting me know.
I ran chkdsk like this.
Plugged in the micro sd card in the computer, went to my computer and right clicked the SD card, clicked properties, went to tools and then error checking.
Selected both the check for system errors and scan for bad sectors. Started it and 2 seconds later it closes and doesnt actually do anything taht I can see. I go back to the sd card and still nothing has changed.
Where should it be putting the recovered .chk files?
Cant wond scan via windows, so i did it by cmd. Said it couldnt convert threads as there is no room. So I'm guessing I have to format it first. I hope this doesnt get rid of my files permanently, I didnt have any other copies of my contacts or anything, and phone is completely broken.

[Q] [q] Evo doesn't detect SD card

Hey guys,I was running Unsleashed 3 on my Evo
And after I rebooted it(yesterday),The phone won't detect my Sd card,I tried Astro and some other file managers e it won't detect
I've been looking into others threads since yesterday and nothing works
Also,my laptop doesn't detect the phone even on recovery
and finally,The Evo keeps rebooting itself every 50 secs or something
Can someone plz help me?
Thnx
Well mine won't read as disk drive. People don't like us lol

Nobody?
1-Did you try using another sd card?
2-Take your sd card out and see if your phone keeps rebooting itself still.
3-Are you getting an error notification in your status bar about the sd card? If so, use an sd card reader and plug it directly into your laptop. Copy and paste all the files from your sd card to your laptop. If you have a corrupted file or files on the sd card, windows wont copy it over and youll get a pop up window telling you so. Once all of the files are copied to your laptop, reformat your sd card using windows. Then put it into your evo and reformat it through the phone as well. Then copy and paste the good files from the laptop back to the phone. This should solve your problem as long as its not ROM related.
Just Got it to read on my laptop
What should I do next?
Format it?

try another sd card. if the phone is still not detecting it then you may have a prob with the phone.

You don't have to unroot your phone for Sprint to replace it. As long is it is not physically damage or been exposed to liquid take it to a Service and Repair center and they will order a replacement as long as you have TEP.
did you have to pay 100?
I didn't pay anything but my phone wasn't rooted! I blamed it all on gingerbread

[Q] best way to change your SD card ?

Hi guys,
I have a 32g class 10 sd card I bought to use instead of my 16gb class 2 but I have been facing quite some issues in the last couple of weeks
I took the 32g, put it in my win7 PC, formatted it to FAT32, safely removed it and now the arc doesnt recognize it... I just wanted to format it via the settings-> storage -> erase card in order to make sure everything is all peaches and cream before loading 20+gig of music in it.
...
All I want to do is finally transfer all my music (24ish gig) to the new 32g , and back up all my apps and stuff via Titanium Back Up pro.
Simply said, I want to have my 16g card data in my 32g one , with all my beat
Please could someone share some tips or links, I'll do homeworks and have been, but I have been facing so many complications since the last few weeks
Thanks in advance
Does your phone recognize another card properly?
Did you apply a volume name when formatting the 32GB card?
Did you try the 32GB card in the phone before formatting it?
I've done pretty much the same as you with a 32GB card (Kingston Class 4) and had no problem.
Are you sure the 32GB card is good and not a counterfeit?
Try formatting it again to with FAT32, default parameters, short or no volume name. Try copying your files to the card on the PC to see if it actual works.

Thanks I did put a volume name. That might explain it.
Yes the card already worked ( plenty of times ). I have been trying numerous time to transfert the music ( takes forever to transfer 20gig to an SD card , even class 10... ), and had mixed results that always ended up failing ( most of the times because of me... like forgeting to safely remove the sd card from my laptop made the card unrecognizable by the phone afterward...of course I just finished to tranfers the 20gig and was too happy to safely remove it... )
I will try that right now. thanks again
*EDIT*
Bah still same problem I must be doing stupid... SD card is not recognized by the phone. In the settings menu ( storage ) I cannot mount or unmount it and thus format it via the phone itself
That even after reformating it to default FAT32 partition with no volume name using MiniTool Partition Wizard Home
So number 1 priority is getting the SD card to be recognized again by the phone
**EDIT2**
When browsing the card with astro it says problem creating external cache , with root explorer it only says directory is empty. Still can't do anything in the settings menu

Ya I'd love to get to this point ( which I got in the past hehe ) but at the moment it's still not even recognizing the sd card anymore
still formating btw....
How did you recover your issue?
I think I have a similar SD card problem. But, I encountered it after I did factory reset with SD card erase option selected. I didn't do anything after all. When I connect to PC, on the phone upper bar, there is no notification regarding USB. The middle button seems not working either.
Try formatting the card with this Panasonic SD/SDHC/SDXC Memory Card formatter.
That's strange why not just do a quick format in Win7 or WinXP, to FAT32? I use a 32GB as well and Arc has no issue with it. Coming from the 8GB, here's what I did.
1. Take off the 8GB from the Arc and placed in a USB reader.
2. Copy off all the files to your PC. I used WinRAR to accomplish this, just archive everything and STORE it (no need to compress so operation is faster). Or you can just use drag and drop plain copying its all the same.
3. Analyze the copied files and remove all unneeded bloats (ie. old movies u don't intend to watch anymore, clear out useless temp files, etc)
4. Copy back the files on your new FAT32 formatted card using the USB reader, then put in your Arc.
If you notice, the entire data migration is done via card reader/USB. Using the Arc as such will slowdown your progress and introduces unnecessary delays.
You can also use usb tool, it basicaly creates a back up image and can be restored to the new sd

[Q] Micro SD card works on PC but not on S4

Hi,
I have just purchased 64 GB Class 10 Samsung micro SD card with a SD adapter and USB adapter.
I plugged it in to my S4 and everything seemed OK. Copied all of the contents from my old SD. Everything was working fine until I restarted my phone. After restart all of the files were present by could not access them. Some of the files and folders had ~ as prefix. Plugged the card in my PC and the files were corrupted. Recopied everything and tried several times again. The same outcome. Reformatted the card to exFAT and to FAT32 both from my phone or my PC using several available programs. No success. Whenever I unmount the SD card or restart the phone the files get corrupted. So I figured the card is broken. So I decided to test it only on my PC. Copied lots of stuff to it (music, movies etc.) and started using it on my PC. I have mounted/unmounted it on my PC probably 100 times and it works just fine. So that means that the card is fine (or am I wrong???). Also tried it to plug it with the usb adapter into my TV. It says that usb disk is empty.
The files only seem to get corrupted when I place the card in my S4 and unmount it/restart the phone. The card works just fine on my PC.
Does anyone else have this issue?
I am running a rooted 4.3 Android OS.
Thank you!
You have to partition the card into 32GiB chunks. So make two, 32GiB partitions and it will work fine in your S4, except it will show you have two external sd cards.

If you don't want to make two seperate partitions on your external microSD card then do the
following:
Remove your external microSD and plug it into a card reader and or the adapter which came
with the card then plug it into your computer.
Make an empty folder on desktop of computer and copy all files and folders from the microsd
card into the empty folder.
Format your external microsd using this windows utility and copy all the files/folders back onto
the card from your computer and replace it into your phone.
Here is the direct download link for this fat32 formatter which is a windows utility:
http://download.cnet.com/MiniAide-Fa...74ffba47b88ad1
By doing the above your external microSD card should work fine in your phone.
Good luck!

Thank you for your reply. I did as you suggested and it worked for some time. I mounted/unmounted several times and it seemed fine. Then did a restart and the files were corrupted again.
Why does the card need to be divided in 2*32GB in the first place? Isn't the S4 suppose to support 64 GB cards?
Your suggestion seemed to isolate only part of the problem. It remains only the restart. What can be associated with corrupting data on sd card and android restart?

No, it depends on your kernel if it supports a certain FS. I am not sure why your files are being corrupted other than one, your ROM isn't unmounting your card properly on restart or two, your card has issues. Again, I am not sure.
Sent from my SGH-M919 using XDA Premium 4 mobile app
In that case do you suggest I try changing kernel? Do you think that might help? My kernel version is 3.4.0-2082040 if that means something. Do all S4s come with the same or different kernel? Will it help If I unroot or maybe install other ROM for different country or different operator?

All the stock S4's come with the same kernel, so if your S4 is stock then it's not a kernel issue.
Have you tried any other external microsd cards, if not that's what I would do next.
Most of the better microsd cards have either a 2-3 year or a lifetime warranty.
Good luck!
I currently use my old 8GB sd card with no problems whatsoever. My S4 is rooted. Does that change the kernel? Should I unroot?

[Q] External SD Card Read-Only Problem

I tried researching this but wasn't successful finding same exact problem or solution. I'm on 4.4.2 Baseband N900TUVUCNB4 rooted with stock rom and ext sd fix. Everything was working fine until recently. My external SD card has inexplicably become read-only, both on the phone and on my desktop. I first noticed this last week when the phone camera began having problems writing to external SD card, and now I can't sync music to card. I've tried formatting on the phone and desktop, both quick and full but no dice. On the phone, I am able to delete individual files or folders but they reappear. On the PC, I can view but get write protect message when trying to format. Anyone else come across this or have suggestions?

Happened with me once with a different phone/OS. Weird thing is that it was only for a particular SD card. I put a different card and it worked.
It turned out to be a problem with the card (dunno how thats possible though).
What's the brand of your SD card?
I have the exact same problem with my SGNote 2 and SanDisk 64gb micro SD card. First I lost some pics I have taken that day. I searched through with a file rescue tool but they were nowhere to be found. Deleted files reappear, and the ones I copied from internal SD dissappear.

It's a SanDisk 64gb class 10.
Glad to hear I'm not the only one. Maybe we can share the solution when we find one. I'm using internal memory in the meantime for new media files, but frustrated that I am not able to use the rest of the memory available on my card.
SanDisk works fine for me, maybe your sd card is a faulty one, let's wait for a while here and maybe someone could answer your question and hopefully solve your problem

Thanks, Lorettaa. It seems like that's the only option right now, since I can't find any other info about it on XDA. I know Kit Kat has that design "flaw" where apps can't write to an SD card, but I can't even write to it, modify it or reformat it on a PC. I have full read access to every file, just can't do anything else

I have the exact same problem, i tried many options , used some softwares in windows to format , wipe, fix, modify. nothing works.
One possible reason for this problem is file system errors , which can be rectified using the 'error checking' option in windows and 'fixing the file system errors'
But that doesnt solve my problem, even after formatting using advanced softwares, the sd card is the same - no files deleted, no files added...
The fat as well as ext4 parition is not formattable now in anyway.so the possible conclusion is 'sd card is going to fail'.. Take a backup before you loose the read capability.
Recuva is a good, free tool (from the people that make CCleaner) to deleted recover photos.

And one possible reason for a false error condition is a corrupt system. This is normally an unlikely possibility but it is very likely on devices that have had partition images written to (i.e. a flashed ROM). If you have done all you can to the SD card and if the errors are not only on one SD card then wipe everything and load a backup. If you still get errors then wipe everything and revert to stock to see if they still occur.
