How do I fix a drive with data cyclic redundancy error?

Hello,

I was trying to use chkdsk as some people said it will work. But it didn't.

I am trying to format my micro sd cards via my sd card reader. But both seem to give me the same error. One card was working properly about 3 days ago, but O thought the card is having some problem, but I tested it with the other card, and it gives the same error message.

When I am using chkdsk, it is giving me an error that says,

"The type of the file system is RAW.

CHKDSK is not available for RAW drives."

I was using this command (my cmd was ran as an administrator), "chkdsk /f /r /x D:", and I got mentioned output.

When I try to create simple partition, I get next error message,

"Data error (cyclic redundancy check)"

I can't seem to find anyone using it.

Thanks in the advance!

Sincerely,

Tad
