SD card not functioning well

Why is it whenever I transfer files into my 128g SD card, all those files gets corrupted.?? It consumes space but the files can’t used…

Hi, you can plug your SD card to another PC to check whether the SD card is corrupted. If so, you can try the following ways: 

1.Using CHKDSK Command

2.The format SD card in Disk Management

3.Assign the New Drive Letter for SD Card

And if you think these ways are helpful, I recommend the site that has detail steps in soling the SD card not reading and corrupted issue.
