[Q] Weird issue - not able to make modifications on external SD card - Galaxy S 4 Q&A, Help & Troubleshooting

Hello,
I'm having a strange issue...I am not able to make any modifications to files on my external SD card either directly through the phone or USB via my computer. Operations on the internal SD card work fine.
To be more specific, the changes I make will not "stick" after a reboot. When I say changes I mean anything, whether it's moving, copying, editing or deleting a file(s).
An example of this is if I move a file to the SD card through the computer or on the phone, it will work and show up. Once I reset however, any changes I made will revert, just like I never did it. I attempted to re-flash to a different rom, but I'm having the same issue.
I'm not sure if it's relavant, but I was originally using Slimkat 4.4.4 (build 9). When I flashed a different ROM to see if it worked, I used CM11.
Does anyone know what might be causing this??
EDIT - Please disregard. This appears to be a known issue with Sandisk memory cards and not an issue with the phone. Guess I'm SOL and will have to buy a new one since I got it in 2013...
Thank you!

Damaged SD Card?

Hey guys,
Was using my Vega fine the other day...
Was using the new shuttle tool to read from a usb stick and all was working fine. Gone to use it today and it says the SD card is damaged and can't read it?
Have i done some thing wrong?
Its telling me to format it but i dont want to do this as it has ALL my apps and everything else are on it!
Can you connect your SD on a computer?
Then you could try and backup your data, format it and restore data back onto your SD.
Will give it a go!
Nope, it is still showing as corrupt!
So means I need start all over again right? What could have caused this then?
Do people take a nanodroid back up and save to a PC for just this occasion?
Ok, have got the vega ok again however all the Apps that were stored on the SD card are naturally not working, says that they are not installed... so going to the market on the vega I can see about 10 that are not installed.. have installed these and all are fine. I go to the market on the PC and can log in fine, go to my apps and can see all the apps that are on the vega, however if i now to go to install them again it says i have no device linked to this account? How? I have not changed any thing? Any ideas?

I have also made my SD card corrupt in my SGS.
Corruption on SD card occurs if your phone crashes and you take the battery out (abnormal shutdowns).
But don't know how the Vega could get SD card corruption, you can't take the battery out and as it seems you're the only case here.
Maybe your microSD card was already corrupt when you bought it.
And you first noticed corruption when you wrote to that bad sector on your SD card.
It could have also slowly degraded and more and more corruption could occur.
hi,
i've similar issue, but once i reseat the sdcard it's fine again.
i also notice if i insert a mobile stick it shows sdcard requires format - damage...
maybe it's the format of the sdcard?

If you actually have corruption on your SD then I would suggest you try to test it more extensively.
Calculate how much free space do you have on your SD card and then find data with same size on another computer (actually it must be few MB less than free space on your SD) and make an MD5 hash from those files (create MD5 file with hashes and filenames).
Insert the SD card into your computer or connect it thru your phone/tablet.
Copy those files from your computer onto your SD card to fill it up as much as possible.
Restart your computer and phone/tablet.
Then copy those files back from your SD card onto your computer and verify the MD5 file against the copied files.
It's a strong possibility that you would then notice CRC missmatches.
If not then your SD card is really safe.
My phone says that the SD card is OK, but some files there don't copy back at its full length, therefore become corrupted.

Im not 100% sure i understand... Can you explain the MD5 file bit again pls?

In short MD5 is a short hashed value that is uniqe for each content/file (if file content is the same). With that MD5 value you can check content/file integrity (that some content hasn't become corrupted in a transfer process).
If you're using windows I really can't help you much there, because I use Linux.
I think this one works OK (you can also make SFV, MD5 is not really needed):
http://www.quicksfv.org/download.html
If it doesn't work for you, you can find some more if you go to:
http://www.download.com
and search for "md5" there.
Microsoft has also an app for checking file integrity.
Or you can google for "md5sum" for more info (google knows everything).
are you running a custom rom or stock rom? The reason I ask is because I have had errors on nearly all the Modaco roms I have tested and the solution was to use moddedstockv2 and upgrade to vegacomb9 (I know it seems extreme but it is a much more stable rom than the modaco roms in my experience)
Loui - I on th latest Vegacomb
Yani - cheers for your help mate.
Ah well it may well be just a hardware problem then (I'm sorry I know that is not much help to you) perhaps you could tell us how lod the stick is or if you have been copying lots of files to and from it.
The reason I ask is because all things have limits and expiry dates even if they are not shouted about on the packet; Maybe the stick has reached one of these limits. If not then you could probably get a refund from the store you bought it from or a replacement from the vendor (as I recently got for western digital hard-drive that had SMART failure)
Also is it working okay now or have you had issues since the corruption?
The card is only about 3 weeks old, has not had much use if honest. Seems to be working ok now although since the market issues I have not been using it any where near as much as before so I cant give an accurate answer.
I think it may have been me messing around with the host mode or some thing as it did say i had removd a card that was mounted... i hadnt, i had just turned some thing off... so it could well be that which caused it!
Thanks for the info though mate, might see if can get a refund!
Hi, I had the same issue, I had tried to move an app from tablet to SD card I then got the same error message about the SD card needed too be formated. Check your card in your PC, it will most likely be OK. I then reinstalled vegacomb 3.2 update 3. Make sure you wipe cache, factory reset and wipe Delvic then reinstal.
That will fix the issue, the chances of your micro SD card becoming unstable after 3 weeks are slim.

I often have this problem but after a restart it works again.

[Q] External SD Card

Since I have my Note 3 retted have a weird problem where I have cause not yet obsolete.
If I remove or something new place in my ex sd card and restart it, then that is negated and then state that I did not delete it again, or is that beyond that I have is gone. Posted
Ie mn card is exactly as it was before.
Somewhere is thus always a backup put back but do not know which program is responsible for it.
've Backup program, s removes and then done the same, but that does not matter, then there happens the same. So I think that the unit itself does, but can not find anything in the settings.
Anyone here have an idea?
Gr JB.

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!

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 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.

galaxy S4 microsd card problem

Hello
I have SanDisk 64gb microsd. I have not done anything to the phone and now periodically the phone stops reading the 64gb card .It does not say unmounted just when I check gallery the photos are not there and I have to restart the phone.
I have a rooted 4.3 ROM..The only thing I can think of is ES file explorer potentially caused issues. I noticed things acting weird after I used it when I do heavily.
Please help. Any and all advice welcome. Thanks
Tried to re flash a nandroid still issues. I noticed in general my touchwiz is running so slow. I flashed sacs red theme about a month ago. Not sure if that had anything to do with it. Should not have.
It will reread it when I remount it or reboot. Not sure specifically what is causing it though.

Have you tried searching the forums for sdcard fix? Google it? There have been issues with 4.4 and sdcard reading issues. Also downloading foldermount from the playstore has helped others with issues. If all else fails reinstall rom.
Sent from my SPH-L720 using XDA Free mobile app
I searched on Google and there is not really a concise answer as to why this happens. It is a very ambigious issue, however; it seems to be a reoccuring issue with SanDisk cards and 4.4 KitKat ROMs.
What I did was completely flush out and re-installed both custom recovery and my ROM to 4.2.2
It is disappointing because I really like my Samsung Galaxy S4 phone and you'd think upgrades mean better quality product when it has not. 4.4 KitKat ROM is not that good. I don't like both CM and TW versions of KK. One feature I do not like with TW KitKat is the inability to hide icons. There are also issues with battery drain and free hotspot mod.
I don't know what is going on. When I plug my phone into the computer I can access the SD card. When I check the phone it is not reading the SD card. Don't know what the problem is.
Have you tried a different SD card? That would help you determine if it is specific to the card or potentially a phone issue.
What I will do is try and format the SD card with the phone, then put everything back on. So far, I have isolated it to ESFile explorer. Initially I did not update the apk and thought that would work. It did not.
Here's what has happened:
I use ESFile explorer to access the SD card. Then when I went into clockworkmod, I tried to delete a nandroid copy I made. It says 'failed to delete'.
Then the ROM and sdCard do not work correctly anymore, so I have to wipe and re-flash an old nandroid.
Makes me wonder if something is corrupted in the SD Card. Everything used to work fine, but now whenever I access the SD Card with ESFile explorer, even the old version of it, it causes issue.
There is a problem with some Sandisk SD cards. Evidently there was a bad batch. I had some of the same issues. My card was bad. I went to Sandisk's website and they replaced it for free. I was without my card for a week but I got a new one and everything seems to be working fine now.
Can you explain how you did this ? So an update on my situation. I can read the sd card but it will not format and nothing can be written to the card. I tried using recovery and touchwiz to format and it fails.
Can access what is on there but cannot write or format anymore. Any ideas ? At this point I swapped to a new SanDisk card I had lying around. Don't know what to do with the old card

I assume you are asking me how I got my card replaced. I did some research and found the issue mentioned here on XDA as well as on the internet. I went to Sandisk's website, http://kb.sandisk.com/app/answers/list/kw/microsd microsdhc/, and did some more research. I finally contacted their customer service and they told me the process for getting the replacement shipped. If I were you I would just contact their customer service on their website and let them run you through the process.

[Q] Major Camera Glitch after update to Rooted NI2

Did the update to my S5 from rooted NCG to rooted NI2, everything works great BUT having a major camera issue.
When I take a picture, and immediately review it from within the camera app, it does something to the picture. They show up as a grey screen. When I try to review them in the gallery, they show up as these grey broken thumbnails. I can't send them via MMS. It says "can't send file".
Now, if I take the picture, back out of the camera app, and ONLY review them in the galley app, they are fine. This only happens if i review them with in the camera app.
Now, here's the thing , this only happens when the pictures save to the SDcard. If it saves to the Phone's storage, there's no problems.
Didn't happen on NCG. Does this have something to do with the Secure Storage glitch related to Root and Xposed? I just deleted the secure storage module, and it's still happening. (Don't use S-Health so it didn't matter).
Is there anything I can do. We just had triplets, and we're taking A LOT of pictures, and just realized I've lost half of my pictures. This sucks.
Do I re-install the stock camera app? If I do, where do I find it?
Please help. Having root, isn't worth not being able to use my camera.
Can't format SD Card, SD Card is Write Only?
Since this issue is only happening when the photo's are saving to the SDCard, I attempted to FORMAT the card.
Using the phone to FORMAT, the phone UNmounts the card, says preparing, and REmounts the card exactly as is, without formatting it.
So I tried to reformat it on the computer, three different times, three different programs including the Windows 7 utility, ALL of them gave me the message that my SD Card is WRITE ONLY?
What the heck is that? Did the NI2 update do something to my SD card? Did it corrupt my SD Card?
Any one have any ideas? Guesses? Similar experiences?

Never heard of that one...
Do you have exposed installed? Any other MODs? Install any apps that mess with permissions or SD Card?
If no to any of the above, backup all of your data (sd cards too): wipe the entire phone (including SD Card), ODIN back to an older rootable build, and start over.
Pretty sure it's the SD card.
Spoke to SanDisk, they said that something caused a fault in the card, and as a safety measure, the card will become write protected so your data can't be corrupted.
You can copy the data on the card, but you can't add or delete files. So the camera won't record new pictures to the card.
I tried to delete some sensitive files from the card through the File Explorer, and the phone reboots.
I've been using the phone's on board storage, and no issues thus far.
So everything is pointing to the card.
I have Xposed.
The only modules I have loaded is the Moto X tether, YouTube Ad Away, and the Secure Storage Fake that re-enable S Health.
Could one of these mods have created a fault in the card?

Always possible when using MODs. Secure Storage Fake.. what all does that do? It's also possible the sdcard just failed. Things happen.
The S Health mod that changes your secure storage from True to False.
Fixes the S Health crash, and Private mode failure caused by running Xposed on the S5.
With NCG and NHA, I used to physical make the changes in the system/build.prop, and change ro.securestorage.support from True to False.
On NI2, and just used the Xposed module that does it for you.
That's the only thing I did different.

I believe most ROMs here already have build prop set to false (mine does). As for private mode, I don't use it so I couldn't make any mention on that note.
Have you tried another SD Card yet?
I'm stock, so I have to physically set it.
I have a new sd card on order, so we'll try again with a new one.
I really don't use S Health that much, and never use private mode, so I think I'm going to delete that mod and leave it at true.
Then again, it could just be a bad card. My S4, has had the same card (64 gb Ultra) for almost 2 years, a lot of the same settings, and never had a problem.
