microSD disappearance.. SOLVED!

People have been replacing their microSD cards not knowing that the problem is actually in the files and folders..
Ok here it is!
When i scroll through the hTC Sense tabs to music or photos, the applications try to load the thumbs from the Phone/microSD, that's when it suddenly freezes then the microSD vanishes..
I inserted the microSD into my PC and browsed the drive in "Thumbnail view" and guess what happened, it froze.. I figured since the idea was the same in hTC Sense when it tries to load any thumbs..
So i went to the microSD drive again and chose "detailed view" then went into each folder and changed to "thumbnail view" until i found two folders that kept freezing; "Program Files" and "My Music"..
In Program files the only folder that couldn't be deleted definitely had files that were behind the issue.. There was a music album too that froze, i deleted that too...
I backed up my files and formatted the microSD, i had to, because the folders behind the microSD disappearance cannot be deleted even with an "Unlocker"..
So far i'm playing around with my Leo and nothing is happening..
So by viewing the folders on the PC using Thumbnail view, you'll be able to identify the file or folder behind this annoying issue..

I had the same issue
I have (had) Sandisk microSD 16GB card. It was last week that it happened to me. Only backup of good files and re-formatting the card helped.
Today, I was copying 700MB file and suddenly it told me - cant write on a disk. I disconnected cable from the PC, rebooted Leo and SD card was no more present.
I put it into a card reader, tried to format it, but nothing is working. SD card is probably faulty.
So be aware, that that problem might be a first sign before your SD will break.

I think the fault is from some files somewhere in the microSD.. After going through the method i mentioned earlier, up until now my card is fine..

yup right, but be aware. I dont think that normal SD card should perform like that. I am using stock 2GB SD now, and it is ok!

My 16GB microSD is Sandisk and its 100% compatible with this device.. The Leo is doing something when loading the files creating some system files i suppose..

guess what? windows could not load sandisk microSD 16GB and I was already preparing to return it to e-shop, but I tried live cd of ubuntu 9.10.
It can read the card, it formatted it and it is working again! :-D

That's great, so you didn't have to replace it?
But strange, i've always been using the 16GB with my HD and now HD2.. The issue just occurred a week ago..
A day has passed and everything seems fine..
I hope it stays that way..

ok
I got exactly the same problem with my 16G Sandiskin and HD
and found that the problem was a damaged file in my SD
connect your SD to your computer throw card reader, using total commander or whatever, begin coping all SD files and directory to your hard disk, until get a message can't copy "file name", this will be the damage file, unmount the SD and mount it again and delete this file and your SD will be ok
ps: may be you have more than one damage file, try the this method until you can copy all SD files to your hard drive

When you have a write or read problem with a particular file, it usually points to more than just a corrupt file. In my experience with 4 16GB Sandisk microSD, it is the beginning of a failing card. The safest bet is to copy out the good files, reformat in your HD2 and copy the files back. But if it happens too often, it may be time to invest in a new card as your data is of primary concern.
The strange thing is that this usually occurs with the bigger cards, 8GB and 16GB. I never had this issue in the past with smaller cards.
I back up my card weekly or when I have updated large number of files just to be sure I have a valid set in my PC in case the card fails.

I know what you are talking about. Low format may help. I had the same issue with 2GB SD card 3 years ago (had to recover SD card to save few photos) and also on my DLSR with 4GB CF Card (linux helped to read the card). I don´t think it can be damaged so quickly as normal PC HDD, but when it happens often (damaged files on card), it may be a sign of something wrong with the card.

Unfortunately it happened again.. After a month of having everything under control i got the same problem.. The great news is I'm using windows 7 on my PC and when i plug my microSD card via usb reader, i get a choice of scanning and fixing the removable disk...
Now i'm happy without those annoying corrupted files..

My S4 (GT-19505) cannot read SD cards (SD card blank)

Hi XDA Family.
I recently flashed Omega Rom on my Galaxy S4 and everything went well. The next day I played my music from my SD card then there was an error "cant play this music file or something like this" after that my S4 was displaying that my SD card is blank or has unsupported files. The phone recommended that I need to format it using the phone. I formatted it like my phone said but it did nothing. Phone still displaying that SD card is blank or has unsupported files.
The next day bought a new SD card (8gb Scandisk) and the phone read it no problem. I transferred all my music to my new SD card and after playing my music the error appeared again and now both SD cards are showing that the SD cards are blank or has unsupported files.
Re flashed stock rom and stock kernel but still has the same errors on my SD card
Borrowed a memory card reader from a friend and formatted the SD card using my PC formatted it with all know file system. FAT32, exfat and NTFS but everything is not working.
Lastly I tried my SD cards with another Galaxy s4 and they worked without problems, formatted it using the phones formatting capability inserted it on my S4 but still has the same errors.
Any suggestions are greatly appreciated guys.
Thanks in advance.

Any help would be greatly appriciated.

I have The same problem.
Pls help

Hi! Thanks for replying, I was beginning to lose hope that anybody would reply. Tried your suggestion. Downloaded 3 scanning SD card apps on Playstore but none of them worked. Both of my SD card still shows up as blank in my S4.
This only happened after i flashed a ROM, anything I still need to do to go back to stock? Already flashed an official softwas and kernel.

Hi Good Morning!
Tried that last night still the same problem. Tried the chkdsk on CMD still the same problem. I can buy another SD card but I am just afraid that maybe a week or two the sd card will mulfunction again and I cant forget the fact that my PC and other S4 can read my SD cards.

Two possible reasons. Sandisk SD cards supposedly fail easily but yours is 8gb so it should be ok.
Next reason is Omega Rom bug, I personally don't have this issue but I have a similar one. My Sdcard does not mount as r/w automatically.

Thanks for the reply lamstone, I have read somewhere that disabling the automount helps. Can you help me on how to disable automount? and can I do it if I am on stock firmware?
Thanks

Just use the card reader and adapter and attach it to your computer and format the card using exFAT file system. Then use it in phone. AFAIK the current custom recoveries already support exFAT. So you should be fine for anything. I had similar issue with my 32GB Sandisk Ultra card when I formated it using phone. No issues since I formated it as exFAT on PC.

Hi thanks for the reply.
Tried Fat32, Exfat and ntfs and all of the still has the same error. Actually bought a new 16gb sd card earlier I popped it in my s4 and still has the same problem.
This started happening when I flashed Omega rom. Is there anyhow I can check if I have a stock everything? My kernel, recovery and firmware?
thanks for the patience.

BUMP!!!
Anybody who can help me??
Another update is that I installed CWM recovery Philz Edition and tried hooking it up on the UBS cable and mount usb storage. My computer can now see my sd card inserted on my phone. Tried reformat while my phone is on CWM and connected thru USB cable and formatting goes thru but phone still says SD Card is blank or has unsupported files.
One thing that is strange though is that when I try to copy things to my SD card while my phone is attached to the USB cable my PC freezes like it cant copy any files to my SD card.
Any help would be greatly appreciated.

Same problem

I have the same problem. I bought an 16GB class 10 Kingston SD Card and inserted in my phone . Nothing. THen I disabled Developer options and it appeared. Then I though I will reformat it using directly the phone. Ok. Tried to use it bam "unexpectedly removed " and nothing. Then I tried another SD Card and the same happend first good then removed and so the third one.
Any updates on this thread ? Did you manage to make it work ?

This phone is pissing me off. I am having same problems with stock music player and Goohle Play Music app giving errors on any tracks in my Sandisc 32 gb class 6 micro SD. I have started to wonder if it is related to me using the Samsung Smart dock with a 500 gb external HDD to watch movies on HDTV. It mounts the drive and works great but following day I was try to play music that worked day before and now I get unsupported file type error and other error.
I tried avg to check for a virus(which is unlikely imo) and it shows no virus. I just tried this SD on another android device (Nabi 2 tablet running 4.0.4 and all songs play PERFECT without error. This must be my At&t galaxy S4. Any ideas anyone? I really dont feel like reformatting the sd since it seems to work fine on tablet. Also: I already wiped both music player apps in settings and eventually uninstalled and reinstalled the apps (and another musiv player also) to see if it was cache related. This made no difference.
Edit* oops. After rereading OP... I think I posted this in wrong thread.lol. But my issue with S4 and SD card error with music playback is similar so Ill leave my post unless mod wants to remove it. FYI I fixed my issue(somewhat). Ths SD card is fine as I suspected. The phone has an issue having stock music app, play music and mx player. Either one of the apps was running in background or the system was running sound in background. Hope to not have problem repeat itself. I bet custom rom would fix this if AT&T hadnt locked phone with sneaky update.

You can try flash Rom Cook MH8.
I think your problem will resolve.
Thanks

i think you need to try this.. Get your SD card and try to put in another phone example Blackberry (im not sure if it will work on HTC, alcatel etc. except samsung).
then format using other phone. after formatting ffrom other phone. reinsert the sd card on your samsung unit. then check the storage and try reformatting again using your Samsung.

still nothing
Well. I still do not know how to fix this and I searched and tried almost everything. Only thing that I think might be wrong that somehow the "auto mount SD " does not work.
Because the card is there. The phone cannot see it . Other phones do fine. And in CWM even I can see that there is indeed an SD card but cannot acces the files.
So... I really do not know

i am also having this problem but nothing seems to help have tried alot of thing but yeah :/ sp i have given up on it ! it is a 32 gb sd card loved it.. now i almost got anxiety cus i have so little storage xD hehe well well might buy a new sd soon

My class 4 32gb sdcard too stoped working properly these days.Sometimes it gets unmounted randomly or it doesn't get detected or it shows blank sdcard.I don't know what cause that but the best I could have done is to backup my data and buy a sammy 32gb class10 micro sd.I heard that S4 has problems with sandisk ones.

UPDATE:
My SD Card problems has not been fixed until now!
I just flashed the leaked 4.3 firmware and I tried to insert an SD Card just to try it and BAM! it worked!!! I am now afraid of rooting my phone because maybe the SD Card will not be working again but as long as my SD Card is working I am good!
Anybody who has problems with their SD Card should try to flash this:

Need help with 64gb sd card

hello...here's my problem:
I just purchased a 64gb sandisk sd card and it doesn't not work...
more specifically:
1) whenever i re-insert the sd card, it shows "blank sd card, need format" (ONLY if i formatted the sd using my pc before i insert it back)
2) i tried to format to exFat and FAT32 through my pc, it works..but when i insert it back, it's gonna show either "blank" or not able to read any files that i copied to it.
3) when i connect it (inserted to the phone), i cant move a large number of files, it's either gonna disconnect or some errors.
4) i notice whenever i managed to copy all my files to sd, after reboot, it's gonna show "blank sd" again.
5) i also try copying the files to the phone first and then move them later using phone's application, but when i wanna use those files, it's not usable.
6) i think sometimes it deletes all the files that i moved from phone to sd card.
Please help! any suggestion will do...ihv been looking for answers in this forum for like 3 hours.
(English is not my first language so bear with me)

do not use sandisk 64g, mine got file not found at random, using 32g is fine

As mentioned sandisk has gone downhill...Ive had issues with them also. That said it sounds like your card is no good. Return It if you can
Sent from my SM-N900W8 using xda premium

If you can return it--recommend the Samsung 64gb Class 10 on Amazon
ZERO issues and pretty fast

Did you try to format it with your phone ? not PC.
Because i also have Sandisk 64GB micro sdcard i had it since Galaxy S3 and now use it with Galaxy S4 , and have zero problem with it , it works just fine. I keep it almoust always full and even encrypted it.

[Q] Weird MicroSd issue

Hello world,
I'll try to make it as short and accurate as possible. I have an S5 SM-G900F and until recently I was using a 32 GB micro sd card (formated in Fat32) that i had on my S2.
A while back the card just unmounted and died (i tested in another phones + on 2 pcs through card reader).
1st i bought a 64 GB card on ebay (a cheap one) and when receiving it I had 2 issues: the card was slow to read/write and no matter what method was used and how many files were transfered, after a reboot it would only display the first +/- 7.5 GB. The remaining folders remained, but with no files in them. I thought the card was defective and got myself a new one but went for a 128GB this time Read/write speed were correct but i still had this +/- 7.5 gb limit on it. I do not have any phones to test this time, due to the capacity, but on several computers, the size of the microsd card was correct and when connected through USB OTG when i had more that 10gb files on it, they displayed and played just fine (movies and music). It appears that the phone just "deletes" files going over the 7.5 GB threshold. I used the following methods to copy files to the card:
1. USB cable and MTP.
2. Card reader
3. Over wifi using ES File Manager
I thought that maybe the stock kitkat rom i had was the problem so i upgraded to a stock lollipop 5.0 (spanish one) but i have the same issue. I even tried unrooting the phone.
Has anyone ever encountered this kind of issue? Does anyone have any suggestion to try resolving this?
Feeling desperate here

can anybody help? please

Hi :good:,
Sorry to hear that you are faced with a Defective SD Card. Stop buying from ebay as the sellers most of the times are not authentic and the electronic products you buy will be fake from inside but looks absolutely genuine from outside.
Currently ONLY 'SanDisk' and 'Samsung' produces 128GB mmc card.
Try to reformat the Card as Full Format in Windows and check if it works.
if not then Delete the Card partition from Windows. Put it in the phone and it will be identified as Damaged Card. Go ahead with clicking the message and the Phone will Auto Partition and Auto Format the card.
If its still not working... then you are married with a Damaged Card.
Check if you are accessing the SD Card Folder over WiFi not the Phone internal memory Folder which is anyways will be much lesser. KitKat do not allow accessing the SD Card to 3rd Party Apps but there are few tricks here in XDA (search for it) which will overcome that.
Happy Troubleshooting.

On custom rom or stock rom?

I have exactly the same issue. Tookk me a while to realize it was on SD, but now it is confirmed. If I take pictures (or I receive pictures on whatsapp) they are fine for a few mins and than they disappear. In some cases just a few mins after disappearing I can find an icon with a trinagle and a !. How did you solve the issue? did anyone else experience it? Is Huawai aware of this issue with their phones?

I have same problem on my P9 EVA-L19. Phone somehow locked SD card, and no changing content, but I can see all content. It is NOT POSSIBLE to add or delete files, even to format card. My card is Transcend 64 GB Class 10. Phone is not rooted, I use Android 7.0, never playing around with custom roms.
Is this fixable? Can we somehow solve it?

I have the same. Currently on my 3rd card now in almost a year.
I learned the hard way to replace the card the first time my phone finds corrupt files.
There seems to be no return from that, only temporary fixes.
