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] Strange problem with 32 gb card

Ok, so I'm going crazy now, but I just can't figure out what's wrong with my card.
I bought a new 32 gb card. I know, I know, you're gonna say it's a fake card, but it's not. I tested it with H2testw and it fill up the card with 32GB of random data.
So, here's what's happening.
1. The card came formatted, I just swapped it with the old card and the Tab recognized it without problems.
2. I took it out and copied backed up files from the old card onto it.
3. When I put back the card into the tab, only a few folders were visible and other data that was copied and visible via the card reader was no where to be seen on the tab.
4. Then I took it out and tried repeating the process - same thing.
5. I tried quick formatting the card through the PC, and tried everything once again. Now the results were different, but again not all folders were copied.
6. I tried formatting through the Tab. The format went fine. Then I tried copying files through the USB cable (mass storage option). That also went ok, but a few of the files could not be opened. Scanned it with disk check and automatic fix error option.
7. Back to PC, did a full format with a Panasonic sd card formatter. Ran H2testw. No problems. Put the card back, re-rooted the tab (since I started suspecting it could be somehow related to this).
8. The card is back in the Tab, but it's still showing some strange behavior, such as folders dissapearing or files not being readable.
Anyone have any idea what to do? I would also like to note that the card works fine when in my reader, I can copy files to it, open them directly from the card etc. No problems at all. But as soon as I put it in the tab it goes crazy.
P.s. The tab is rooted, firmware is out-of-the-box. I have app2sd, but I didn't put any of the apps on the old card, and all apps work normally with or without the sdcard.

I dunno. Bad card? Or maybe just incompatible with the Tab?

just wait android 2.3 to fix this program
Sent from my GT-P1000 using XDA App

the card is fake,
i had this a while ago, i could copy files over fine and the files showed in the file structure in windows explorer. BUT if i restarted the computer loads of the files went missing, i then found out the 32gb card was in actual fact an 8gb card but some trickery makes it look as if you have copied 32gb over. the best way to test it is to copy over say 25 films at 1gb each, see it copy over, restart your computer and then see how many are left after the restart, you will then see how big your card actually is!! Sorry to be the bearer of bad news but i hope you can send your card back and get a full refund.
I have tried a genuine 32gb card from expansys which works correctly in my galaxy tab (JM6 firmware) and my x10i.

AFAIK only Sandisk and Kingston make 32GB microSD cards now.
I got my Kingston 32GB card from Newegg and it works great in my Tab.
Where did you buy your card?
I would not dare to buy SD card from eBay or from a store that has no good return policy.

[Q] how to insert a new sd caed without losing data saved on previous one?

android folder on sdcard is not readable.
data folder on sdcard is not readable.
lol.

should be visable if you use a card reader as opposed to just plugging the phone in via usb?and make sure that folder options in windows is set to view hidden files and folders?
I've just tried with mine and I can see the Android folder and the .android_secure folder.
I think DATA is on the phone itself not on the ext-sd?

not sure, but usually the difference between sd cards is due to read/write speeds. best thing to do is read reviews from wherever you're buying the card and see if there are any from people using the card you've chosen with your device (or similar, like another mobile phone at least). if there are lots of reviews saying that it fails after a while, or that it is slow on their phone etc, then look for another one?
I have a Samsung branded 64gb class 10 micro sd xc (with the same "I" and "1" symbols as the one you've linked to, expect mine is plain black and samsung instead of sandisk. never had any problems, except for when i chose a custom rom that was not compatible with 64gb cards. but on stock rom it works perfectly, and even on other roms it will work fine if it's formatted on pc first with fat32 formatter.

External SD card issues

Hi! First of all sorry for my english. Not my best language.
I'm having issues with external SD card on mi note 4 (910H). On KitKat I noticed that some files became corrupt after some time (mainly pictures and videos). Now with lollipop I thought that the problem was solved, everythimg was ok, but now I'm facing the same issues with corrupt files. It seems that mostly everything copied to the SD card becomes corrupt or damaged except for some small files. I've formatted it several times but after some time it comes back. I've read that it's an specific issue with Galaxy smartphones. Anyone with the same problem? I want to know if there is a possible solution or if there's no solution at all.
Sorry if duplicated post.
I have a 128gb Samsung SD card.

probably a bad card. replace it and enable sd card encryption. that way the system can at least detect it.

The system has no problems detecting it. Some people was talking about this too in other forums. Going to replace it and test what you say.

Hi
I have a similar isues with multiple Note 4 's please see my thread , i hope it helps
http://forum.xda-developers.com/note-4/help/please-help-strange-problem-t3030198

I found the possible solution for Note 4 SDcard Issue after dealing so much with it, posting here it may help some people.
History :
If you own an SDXC or 64GB+ SD card with exfat you probably faced suddenly disappearing all the sd card contents where says the sd card is empty, mine started with this and formatting it using Windows, Note 4 and etc goes to same scenario, it actually happens because Note 4 and Windows formatting them using exfat FS.
In this guide you need a windows PC or TWRP or Mac at your choice.
Steps to fix the issue :
I assume only high speed sd cards (SDXC and U1+) with exfat larger than 32gb are problematic with note 4 and smaller size than 64gb can be formatted to Fat32 without any tools already in Windows, so this guide is intended for high end ones, like the one i had Silicon Power SDXC U1 Elite class 10
Metod 1: (recommended)
1. Detach your MicroSD card (most known to be problematic typr sd is SDXC)
2. Insert it to SD Adapter place to your laptop (if your computer has no dedicated sd slot attached to motherboard better use a laptop otherwise use Card reader) and remember drive letter
3. Store your sd content to your pc to restore later.
4. Download EaseUS partition master (free or other type) all will do the job
5. Right click on the right drive letter corresponding for your SD Card and select Format
6. Give it a name Like "SDcard" or what you like then select Fat32 for file system, finally select 64kb for cluster size, and press OK button
7. Finally press the apply button in top left and magic happens
8. Now you can place back your files, your sd card is ready.
Method 2 TWRP
1. Backup your data in an OTG drive or Internal storage or cloud.
2. Boot into the TWRP select wipe menu
3. Push advanced wipe, select MicroSD card, push change File System button.
4. In this menu choose Fat and press the button, wait for it till the a message says successful appear.
5. Now boot to your system and you'll notice it's fixed and you can place your files back.
Method 3 Using Mac OS X:
If you own a Macbook or iMac or anything similar just attach your SD card to it using its Adapter then run the "Disk Utility" app in others folder or type it in Spotlight (don't forget to take a backup already) then Select erase button on the sd card and use Fat in the menu, just you need to do it Twice, then you'll good to go.
I was able to do that in Sierra with latest updates.

SD Corrupt

I've just got a new Nokia 5 and tried to use a Samsung 32GB SD Card, but it starts to format and then keeps showing as corrupt. I can see the card fine on my PC and can format without any problem, but still the same on the phone. It starts to format, 20%, then it stops there for ages and then asks me to move files over. I select move now and then it goes to show SD corrupt. Is it an issue with the card? I've not tried any other card, but was using the same card in an old motorola without any issues.

I almost had the same problem with nokia 5. sd card successfully configured but after a day it was corrupted. i used two different SD cards (SanDisk Ultra 64GB & Toshiba exceria pro 32GB) but nothing was different. I lost both of them because they don't work in the PC anymore. even I can not format them.
