I have sooo many files I need on an SD card and it is coming up with "the file or directory is corrupt and unreadable" I tried the "chkdsk" comand and it then says "the syntax of the command is incorrect" PLEASE HELP
Could you enter in Disk Management and check if the SD card is listed there? Does it have a file format and a drive letter? If there is no drive letter assigned, try using the Diskpart command from Command Prompt to assign one.
It should look like this:
Select volume n
Assign letter =L (or whatever letter you like and is not in use)
I strongly recommend you to check the SD card on another PC or on some other device.
