Looks to me it is a damaged card. Nothing much you can do with this I/O device error.
You may try to download the files onto another drive (if you were able to access the disk, that it).
But have to do it many times, and small number of files at a time. Good luck.

But it does not allow retrieving the files inside, yes? Like will only give replacement card?

This is a bummer. A bit ironic that they are giving a replacement to a product they sold that went konk in the first place.
