I am using 64GB micro SD-Card.
I always put it into my laptop slot for secondary storage.
Recently, I found a big problem that my SD card won't work properly.
When I copy new files to the SD card. Firstly, it appears right. The file is intact and I can access the file. However, whenever I restart Windows 8 or when I wait about a few hours, the copied file is gone! just gone!
But the old files (before the problem appeared) still remained well.
Thus, I tested more. Amazingly, when I delete the old files that means the files that I copied days ago, it seemed to be deleted at first. However, when I restart my Windows or wait for a few hours, It re-appear! Wow...
That does not happen when I refresh the Explorer or press F5. I have to wait for a few hours or reboot my laptop.
In summary, my SD card seemed to be 'held' at a certain moment. Whenever I copy new files, they will be deleted. Whenever I delete old files, they appear again!
Does anyone know similar issues?
Windows 8 SanDisk Ultra 64GB. Class10.
I have another SD card exactly the same model of this one, and that does not have any problem yet.
I don't know whether it is relevant but this problem appeared about when I installed double-twist player. (but I never run this program after I acknowledged this SD card issue for sure)
