[Q] SD card problem

I have a 16gb class 4 micro sd card in my phone and it has been fine. I should have about 1-2gb free on the card and I did until earlier today when it now says I have 10gb free, I had not deleted nothing off the card and my phone was working as it should.
I checked and it seems to be that my music folder has went from 8-9gb in size to 182mb - all the files are still there and seem to work ok as well.
I don't trust it at all and am gonna format the card and start again but just wondered if anyone has ever seen this before

Keep ext sd card clean if unwanted files

Question
I want my extra sd card to only have my media...no and secure or data or any other app crap placed on it
I try and keep everything on the internal 16 GB storage. This way my 64 GB sd card only has my games and movies.
What I have noticed is I can delete them off my sd card...remove it...and restore the app data with titanium back up and I am all good. But after a few days they sneak onto my SD card and take up about 1 GB of space. In effect the files are duplicated on my internal memory and my sd card.
This is inefficient...does anyone know how to prevent this ?

If I understand you correctly and I believe I do, you want to maintain all of your External SD cards space for your media, and if its a 64gig card you want ALL 64gigs free for the media of your choice.
The simple fact that your phone formats that card so it can use it sould tell you that your phone placed data on your SD so not all 64gigs are free. Formatting in general takes some space away from the media for the format to reside. So on a 64gig card, you may end up with like, 62.3gigs or a bit less after format.
I use a 32gig but only 29.8gigs are useable due to format. just saying...hope I'm correct and that I helped you.

Not what I meat.
What bothers me is my phone sees two sd cards ...one is the 16 GB internal memory and the other is the ext sd card.
When downloading an app that installs to sd by default the phone will randomly throw it on my ext sd card if It is plugged in...but if I take the card out it will put it on the 16 GB memory
What bothers me most is all the extra folders and the fact that somethings are in one place and not the other or both.
There needs t be a way for the phone to leave my sd card alone
It gets confusing because the so called 16 GB internal memory on the phone is treated like a sd card by the system and is not part of the system rom....the system rom where most apps is installed is seperate

SanDisk and KingMax have new 64GB MicroSD cards out that the Galaxy and others work on. The problem for me is the price......like ~$150.
To the OP .....Maybe it is the card as I have a couple of Samsung 32gb class 10 and don't have that problem. Whatever I put on my ext. SD card stays there.

I have no problem with what I put staying on my card..it is the app folders and android secure data that my phone seems to duplicate onto my sd card as well as the included internal card.
Check you app directory you will see an android secure folder on your internal and ext sd card...chances are you have duplicate data in each...

There is nothing limiting phones to 32 GBs ...that is just sales material.
I put this sd card in an og droid and n1 and it worked.
Fat 32 can read large drives on a pc so nothing stops iron android either. I have a 2 TB hardrive formatted as fat 32 at home.
Fyi SDXC will allow for up to 2 TBs on your cell phone within 5 years. Prototypes of the micro sdxc @ 2 tb have already been developed.
Hence why the whole nexus internal memory only is bs

Did you ever figure out a way to keep data on the phone only? I have a BIG problem with Evernote (free). I love the program as it holds small bits of data that I cannot remember (e.g. license plate numbers, birthdays, drivers license numbers, etc) but are too personal to not worry about. I only use 1/2 MB (yes, that is right, 1/2 MB) so paying for the premium version is much too expensive for what I store.
What I recently found however, has me ready to stop using it. The program stores all the 'cards' on the SD card of my Samsung S3 phone. And if you pull out the card, pop it into a computer and go to the Evernote folder, they store the data IN PLAIN ENGLISH! So even if I lock my phone anyone who can get the card out can read all this information. I even told the program not to store the data for offline access and cleared the cache/history but it still remains on the SD card if the program is running. I need a way to prevent the program from storing the data on the SD card. I thought I had it fixed - completely remove the program, delete all stored data and folders, pull out the SD Card, reinstall and download my 1/2 MB of data from the cloud (forcing it to phone storage), then rebooting with the SD back in. IT PUT THE DATA BACK ON THE SD CARD! This is a BIG security risk and now I am looking for a way to prevent it.
So, back to your original thread, any luck?

I am having this issue too, I think it had something to do with going from Blazer ROM (GB) to Paranoid Android (JB), and the difference in the way they handle partitioning the ext SD card

[Q] Eating/Erasing Data Off SD Card

I have a SanDisk 32GB microSD card. I originally had one at launch but after a few months, I had a terrible case of Media Server constantly running in the background sucking up all of my battery. I got the card replaced by SanDisk as per a lot of discussions on the forum.
Its bee fine with this new card for over 5 months. Now, out of nowhere, I'm noticing that my Galaxy is EATING my data. Slowly over time more pictures and music files on my SD card are being wiped out. The files stay on the card, but read as 0 bytes and I can't open them.
Last week I lost an entire folder of pictures. No big deal, thats backed up.
This week I noticed half my music library is now a bunch of 0 byte files. What on earth?
I'm going to go home and copy my backup over SD card after reformatting and will report back. But what gives? What is this nonsense and why would it be doing this? I haven't dropped my phone or installed any crazy stuff on it as of late either.
EDIT:
I'm on stock ROM with AutoChainFire root. 4.1.2

What rom you are running? What format you have in your sd card, ie exFAT, FAT32 or NTFS? Highly recommend to format you sd card to FAT32.

FAT32

The card may be damaged or corrupted..
Not uncommon for SanDisk...
Try a clean format to FAT32 and test again...
If the same conditions exist...a replacement may be in order...g

How should I properly clean format?
Because I tried to format straight from the phone. But after 3 tries, it wasn't actually formatting the damn card even though it said it was. I removed the card and connected it to a hub on a PC to do it through Windows.
I know that it technically shouldn't matter. A format is a format. But is there any reason why I ~should~ do it through the phone at all? Or why it would even act funky like that?
I think I need to do a clean install on my phone too. Just to be sure.

Camera images never saved, disappeared from gallery.

To make a long story short, I took some irreplaceable pictures today that disappeared.
I have my camera saving to my 64gb memory card. I took a few pictures and a couple of panoramas and they ended up showing up glitchy and useless.
They didn't appear in the gallery with the exception of a few images.
It looked odd.
I rebooted the phone and tried to go into the gallery and they just weren't there. The previews showed up momentarily and then they vanished.
Now when I try to take a photo to go to my external memory, it works fine. It didn't pre-reboot.
Is there a method of:
A: Recovering my lost 10-15 images.
B: Ensuring that this doesn't happen in the future.
For the record, my card seems to be working fine. Music on it loads up quickly as well as any other images that I loaded onto it. Files open and there is zero lag. I don't suspect that the card is corrupted or anything.
Thanks guys.

You could try something like Recuva: https://www.piriform.com/recuva
I successfully used that to restore files deleted from microSD cards a few years back.

Thanks!
I'm unfortunately on a Mac. Guess I'll boot into boot camp and install it and give it a go.
I hope the pictures actually existed as files though and not some cached object.

Update:
Overnight, the saving issue arose again. I'm forced to use internal storage when using my camera.

I've seen this problem before. So SD cards don't work well with Samsung devices. I bought a Samsung SD card and never seem this problem again. I recommend you do the same.

I wish I wasn't broke :/
I'm using a SanDisk 64gb. Guess I've gotta dig up some cash and get a Samsung.
I don't see how this is an issue though.
What is your card formatted in? My current is in exfat. I'm thinking the format may be an issue.

It may be a kitkat issue. Google "kitkat SD card write". Root users are using a fix that sets permissions so the sd card can be written to by all apps as expected.

Right before I came across your post, I found some info on the kitkat issue with sd cards. I'm guessing that's what's causing this problem. Odd because it's the default Samsung camera that's messing up.
Oh, how I miss root. I just hope we get root soon. I'm pretty close to selling this phone and hopping on Tmobile.

I had this problem happen with very VERY irreplaceable pictures, on my backpacking trip to china, one of the most irreplaceable pictures of my entire life was taken, appeared glitchy in gallery, phone reset and it was gone.
after taking out the SD card, and doing many deep scans to try and recover the deleted pictures, it seems the pictures arent there, which leads me to believe it somehow tried to save it in internal memory (which cant be mounted as a drive, so cannot be recovered).
if you can somehow flash an older version of android (like 2.xx) you can mount your phone as a drive, and then attempt to recover deleted data from your internal SD..
yeah all i can say is ,,|,, you samsung.

I too have the same problems as the OP. And I am on SAMSUNG micro SD card! Guess it is one of those first batch gremlins?
However, I think the problem has gone away after I switch on the image "preview" option. Give it a try.

I had the same issue with a 64gGB SanDisk micro SD card. The camera would seem as if it was taking pictures but nothing was actually saved; they just shows as corrupted files in the gallery. I lost countless irreplaceable images from our honeymoon because of this. Once I switched to a 32GB Samsung micro SD card I never had the issue again, also saving the pictures directly to the internal memory solved the problem. I use the SD card for music as well so it has to be something with the phone writing to the SD card. From what I've read it's a issue with the compatability with samsung and non samsung sd cards for some reason.

Never had this issue with any of my Samsung phones (S2, S4, and now the Note 4). I'm using a SanDisk Class 10 32GB. I'd recommend pulling the files off the SD and doing a format. Download the App SD Maid as well for routine maintenance on your SD. Good luck.

My 64GB SanDisk SD card was giving unexpected unmounted errors, so I picked up a Samsung 64GB SD card. The unexpected unmount errors went away, but now I have this problem. Pictures are not saving to the SD card correctly. Sometimes it says media not found. Others the preview/thumbnail looks fine but the full view is just grey.
I am going to try saving to internal memory and manually moving to the SD card as I run out of room.

Second time having issues with 64gb sdcard

Hi all,
I am getting very worried with this LG g4.
Last December I had a big issue where I was taking pictures and saving in my sd card, and when the card got a bit full(not totally) all photos taken from a certain point in time were corrupted (normal size but no thumbnail and I could not open them anywhere), as conclusion, could copy existing, could not delete with external software, or in any other day.
End up complaining to amazon and they have sent me a new 64sd card, this time from Samsung.
So far so good, until yesterday where I took some pics and realised the last ones were not appearing as thumbnails. My thought: the same issue again. Decided to restart phone...
Error no sd card can be mounted, it is corrupted!!
Restarted again, tried on another phone, still corrupted. I cant open or see any data from it. It says I have to format?
I don't know if I will lose all my data, and I am thinking about presenting a formal complaint to LG. It must be the phone!??
Anyone with the same issue?
Thanks Tiago

It might be your phone or just a couple bad SD cards. I had an issue with the SD card they provided with the promotion, but it was a different issue. There was no data loss. It just prevented writing to the SD or deleting. I had no problem copying files off the card. Since my 1st SD card, I bought a SanDisk Extreme 64GB. It has worked flawlessly for months.
