Invisible Files on MicroSD Card?

All of the sudden, all the files on my SD card went missing! I was transferring music and video files to the device over USB (as a storage card, per the custom ROM USB/PC feature) and after it was done, it showed my card as blank.
I took the card out of the phone (XV6900) and put it into my SD adapter and into my computer. The 4GB card shows that 1.8GB are in use when I go to properties, however, there are no files at all in the root of the drive! Like they are invisible! (Yes, I have Windows set to show all hidden and system files, so that is not the problem)
How do I get my files to reappear? It looks like they are not actually deleted! i don't get why this happened all of the sudden

you can try an undelete program and check the sdcard while in the reader
undelete programs can handle sdreaders just like they can hd's

Did that already...it found a ton of stuff that used to be on there, but not the current files.

had the same thing happen to me once in awhile
where the sdcard just get corrupt which is why I keep
an raw copy of it on my computer in case I need to copy it back

I'm using the same 4GB card as my old phones. this never happened on my Titan or TouchPro, each of which I have for a year or so. I have had a Vogue for 1 week and it has happened twice! does the XV6900 wipe the card periodically or when performing certain actions? even on a ROM update/flash it should touch the SD card when running from the RUU package in windows

[Q] Phone not recognizing some media files (SD Card)

So I bought a generic Android phone and almost everything is in place. The phone seems to have a problem recognizing some media files, I've tried formatting the SD card, no luck. I've also tried to convert them in different formats, only some additional ones show up. I've also tried to change the location of the files, but again only 1 or 2 more are recognized.
I don't think it's the Micro SD's problem, I already checked it on my computer and the files are intact. My tablet is also recognizing all the media files properly.
Does anyone know why this happens?
Solution?
System Information:
Android 4.3
Mtk6515
Thanks
EDIT: I'm also not able to see folders inside folders except the android system's.

not clear, wait for the answer

Can you tell us what android device you use? Try be specific please

Playing .mkv (samsung tabpro 10.1)

Hi all,
When i put mkv files on external micro sdcard by a usb to microsd adapter.
The mkv files dont play on mxplayer on my samsung tabpro.
But when i use kies software from samsung and put the files by connecting the samsung tabpro directly to my pc.
The files come under DCIM/Camera/mkvfiles on the microsdcard the they play with mxplayer.
Just to let people know here.
Seems very strange huh.
I wanted to buy and still going to if all works on mxplayer.
But i search really hard why my mkv files did not play on my samsung tabpro.
Any reason why i need to use samsung software to put files on the microsdcard to play mkvfiles.
greetings

Hi,
This is very strange because storage location does not affect playback at all.
If you unplug USB connection immediately after copying file, file can be corrupted because file may still being copied by Windows USB driver or Windows file system. Use "Remove device safely" menu on the Windows notification bar area. It will ensure file buffer being flushed.

It's due to the android restriction introduced on Kitkat onwards. It prevents the third party applications from directly writing on external sdcard. They can ony write in their respective data folder in sdcard. If you have rooted device then you can fix it by downloading a simple application. Else you have to use Samsung file manager.

As @bleu8888 said don't unpulg the usb device during copy.
Sometimes background process may still copy. Before unplug the usb test the copied file is whether playable or not. If you are still unable to play check the hash values of both files (like md5 or sha1) to ensure the file integrity. Most of the latest file managers like es, Fx can do this. If it doesn't match there should be some problem on your samsung file manager.

Hi,
I think its indeed a read and write problem.
Going to have a look into this.
Maybe root if i find more info about it.
Thx

I do have kitkat with same restriction.
Other apps can't write in microsd in my device too. I am also using samsung file manager to copy any files to microsd card. But, I can play everything whatever I have.
If you look at your case, other then it's data folder mx player can't write anywhere. Even mx player can't write in DCIM folder. But, it's playing well when you copy through kies means your file is complete. It seems that when you coping from file manager it's getting corrupted or not completely copied.
To copy files there is no need to use kies. When you connect in mtp mode your device will be listed as media device. If you open that it will show both internal & external sd. You can copy to any folder.

Indeed no need for kies.
The issue seems more my sdcard itself.
I have a couple 64gig class10 sandisk here.
Restriction from pc to tab is very bad. But if i use cardreader seems like i can write on the card again.
But i have probs with 64 gig sandisk very strange.
Its like person above said movies are like not fully written on de sdcard.
But I realocated the partion on itand formated it now it seems ok.
So Sdcard was like 59gig partion and 3gig other partion and i scrap and made it only 1 partition in total seems it write much beter now.

ES File Mgr Issue With SD

I'm using ES File Manager to copy files from my computer to a new Note PRO. I can copy files to the internal storage but I can't copy to the external SD. Also, I cannot use ES File Manager to move files from internal storage to the SD. I can use the stock file manager to move files between internal and SD. So the questions are:
1) Can ES File Manager be made to copy files to the SD card?
2) If not, then can the stock file manager access Windows devices to copy files from the computer to the SD?

Likely the Kitkat SD write permission issue. See here:

Yep, that looks like it. Thank you. I'm not ready to root yet to solve the issue. I was not able to tell if this is a bug or by design. It's pretty limiting.
Still trying to figure out if the built-in file manager can be used to copy from a Windows computer to the SD card.

If you connect your tablet to your windows PC you should be able to access internal and external sdcard. They will show up as separate drives. If they don't, install Kies 3 then connect your tablet again.

I was hoping to get this done using wi-fi just for the convenience. It is something I did with previous devices. It always surprised when a basic feature goes away.

If you have an FTP server installed on your PC, My Files app can pull your files that way, then save them to external sdcard

ES File Explorer implemented the workaround within the first few days of KitKat's release. I've been using it to move files in all directions to and from my MicroSD on my Note 3, S5 and NotePro for months without issue. The main thing that doesn't work is renaming.
However, the WiFi transfer to MicroSD has been blocked by Google for security reasons after a series of WiFi-related file security problems. No file manager is capable of this without Root. Same as how you can no longer download files off the internet directly onto the MicroSD.
It's much faster to just pull out the MicroSD and plug it into a PC, anyway. The transfer protocols on Android are a nightmare.

Error copying files from PC to S10e using USB cable

I have a weird issue when trying to copy multiple files from pc to phone, using an USB cable. In about 95% of cases, the copy process gets stuck at a random file... ("Copying..." and the file name is displayed meanwhile). After some time I get an error message "Cannot copy file <file name> . The device has either stopped responding or has been disconnected. Stop copying? / Skip this file / Cancel" . The file is always a different one.
The more files I try to copy, bigger the chances to fail. If I choose Skip, the copy continues but chances are it will get stuck at another file and so on.
Files are pictures, movies mp3s, it doesnt't seem to matter.
For the moment, the workaround is to repeat the copy process until the number of files in destination matches the source...
I can copy just fine anything (lots and lots of GB) from phone to PC, using the same USB cable, without adjusting it, before and after the failed copy from pc to phone.
Phone is Samsung S10e up to date
PC is a Windows 7 x64, all 4 USB ports behave the same.
USB cable looks fine as far as I can tell
I wonder if someone experienced something similar or has some idea on what to check.
For the next week I am limited to the hardware mentioned above.

What prog you use to copy?

Update:
Changed cable, no difference
Tried on another win7, same behaviour (error copying to phone, on random files)
Tried on win 10, copy from phone fine, copy to phone does not show error, yet randomly some files are not copied to phone (?!).
I used windows explorer to copy.

Make sure you get a high quality cable. Post a link to where you purchased your cables to warn others ^^

Both of them are original Samsung cables.

wow.

Having experienced similar troubles copying from PC (Win10 x64) to previous phones (S4mini) via USB cable, I now avoid this method. Instead, I copy files from PC to 64gig microSDcard in a USB thumb drive adaptor. Then I put the card into S10e and sometimes copy from card to internal storage. It's actually faster this way than from PC directly to S10e internal storage, especially when I want the files on both of my S10e's. This phone is really fast moving files from its external to internal storage.
