My micro sd card is working but i can't open the files

[1888persona]

Hi all,

Recently, I have an issue opening files on my external micro sdcard on my Android smartphone running Mashmallow 6.0.1.

The files look intact as I can view the properties with full details such as file name, size, resolution, type, etc. However, when I try to open them, error messages such as below surface:
- file type not supported, cannot read image
- cannot read file, invalid pdf file
- cannot support file, video cannot be played

I copied these files to my PC and tried opening but to no avail. Same messages appear.
Have also tried searching around on website but could not find solution to date.

I honestly do not know what has gone wrong since after running chkdsk in cmd, it appears there is no bad sector. I have tried Testdisk but it is not working too.

Anyone has any idea how to resolve this? I do not want to reformat the card yet as those files are very important to me. My biggest mistake is not backing it up often enough. 🙁

Thanks.

In Android Marshmallow, you have to nominate the SdCard to be used either as Internal Storage or Portable. Which did you choose?

I can't thnk of anything in Android that could corrupt data to that extent.

When you put it into your Windows system, what file system did it show? Find it in Control Panel>Administrative Tools>Computer Management>Disk Management and right click on the disk.

I'm sure that Marshmallow wanted the NTFS file system to be on the card before it's installed. It would make sense since most cards will be put into a Windows system at some stage.

It doesn't sound too good for your data although a Linux or Mac system might have some luck so don't give up on it yet. If you have another card, try formatting it under Windows with NTFS, put it into Android device and copy some files on to it.

If they're readable later in the phone and your PC, you've fixed it.

The phone couldn't recognize the card with ntfs and wanted to reformat it using fat any other ideas?

It was worth a shot but it doesn't look good for those data. Maybe a Linux system can display them properly but it's pretty unlikely.
