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..

[Q] Can't format my sd card!

So about a week ago I downloaded new version of icecream tosti's ICS rom (v0.6) and booted into CWM to mount my sd card and move the zip file over. I noticed that it was taking longer time to move the file than it usually does but I let the process finish. I unmounted the card and went to install the zip from sd card but couldn't find it. I tried to move the file again and again but couldn't get it to copy the file onto the sd card. I tried moving files from the sd card onto the computer but that was not possible either. It wouldn't show me errors and complete the moving process but it actually didn't move anything. I thought there was something wrong with the sd card so I tried formatting it... no success!
I have used easues partition manager, mini tool partition manager, hp sd card utility, panasoic sd card formatter, tried formatting it through windows native options, used disk management, even tried formatting it through CWM but i kept on getting the same error, can't format. I was placing the micro sd card in a usb card reader and sd card reader in order to format it through computer. I have also tried using different computers but that didn't solve the issue. The problem is that every time I try to install a rom it reverts back to an older revision of the rom with old settings that I set before. It seems to me some how the sd card is locked in a previous state and it is write protected and won't let me format it.
Does anyone have any ideas on how I can solve my problem or does this mean the sd card is gone and I have to buy a new one?

I have exactly the same problem after using NexusHD2-ICS-4.0.3-CM9 V1.3. It seems this sd card was frozen, nothing on it can be changed. If I copy a file to it on computer, it shows copy successful, but that file cannot be read, and if refresh it shows nothing have changed in the SD card.
Anyone have any idea about this?
I have three broken micro sd cards now, two from WP7 and this one from ICS.

I waited a couple of weeks for someone to answer on this forum and tried all methods possible to format the sd card or revive it somehow but no luck so just recently purchased a new sandisk class 4 sd card hopefully this one doesn't go bad either. I just wish I knew why it was happening so I don't repeat the process again and end up damaging the card.

Have you tried to format with MAGLDR and after it on windows 7 pc ?

I did that, also followed this post:
http://forum.xda-developers.com/showthread.php?t=1283232
Contents on this sd card just refuse to change.

is there a solution to this coz im having the same problem and cant find a way to fix this

you can do it by this software's :
HDD Low Level Format Tool
MiniTool Partition Wizard
EASEUS Partition Master
Partition Wizard Home Edition
.
.
.
.
but i dont know how create swap and ext4 partitions on sd .

This happen because you formatted the card on the phone. I never recommend to format on the phone the cards but on PC. Try the application I posted on computer with FAT32 in 32768 unit size.

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.

If you corrupted your SD card rooting............

Or you could just use SD Formatter 4 for even faster easier fixing.

After using the scan dish program several times I noticed the SD card was not recognized by teamwin recovery every time.
It could have been a fluke but I think.
The MS DOS commands in the OP are more reliable.

I'm using lenovo A7000 and recently updated marshmallow and chosen 32GB SD card as internal memory. It was worked as internal memory perfectly quite some time, all of sudden I got message that SD corrupted and doesn't show data stored in the card, it shows zero files, I lost all media files!! However USB storage option in settings SD card shows 6.5GB used out of 28GB. Since it's treated as internal memory I'm not able to read the card in other devices. I have important media files and documents in SD card and I didn't backup them. I'm bit worried!!! How to recover the data from SD card. I assume if SD card changed back to portable, it will format and lose data!!! Please support

I've heard of this problem before. Good luck

After step 9, is it possible to change it to another format type or does it need to stay on fat32?
Also, does the sdcard need to be connected directly to the pc? When I tried list disk while the sdcard was still in the phone (sdcard>phone>usb>pc), it wouldn't come up.

Had the same thing happen to both mine and my wife's SD cards in the Note 4....I think its the phone screwing things up. When it happen to me the phone rebooted and then the card was corrupt. The are like ticking time bombs..

I use the drive format tool from hiren''s boot usb. 1 click and Works like a charm.

We can just format these corrupted micro sdcards by using the Format SD card in the phone's storage settings? What do you mean by 'dont Use the note 4' though?

I wiped it on my computer, then put it back in once android was started and immediately wiped it, it's worked every time so far.

The note 4 will bootloop with the sdcard you used to root due to the fact it has your bootloader original CID stored on it as a fail safe (something messes up during the procedure ) but any device not using said CID is fine ....I used a Huawei ascend to format .worked fine and formatted card without need of pc.
