Can not access to a SD card

Hi khoshtipi, Have you tried running H2testw on the sdcard Google Translate :)

That link is filtered but I try to find that tool by google search.

I tested the sd card by the H2testw tool. It writes "error accessing target"!!

What is the problem!!?

Hi dear pebbly. I think the second has been occurred. Because I have tested many cards by my card reader and all have worked fine. Thank you very much for your replies:)

Now that you know the failure is because your card belongs to a different class than your card reader supports, there is only one option left, and that is getting a new card reader that supports that specific class.

No, the problem doesn't belong to my card reader, as I told above, I have tested many such card by my card reader and all were fine. The problem whatever is, it belongs to card.

As you self mentioned it you pointed to the incompatibility of your card reader. If it can't read the contents of that SD card then its because that class is not supported by your card reader, even though you could have used many other cards. Those special SD card classes are mostly used by professional photographers, thats why its not so common in those card readers usually sold in the stores or those already existing in our laptops to support all kinds of classes. Just mentioning it so in the future you won't get confused if you can't see the contents of a SD card.
Good luck with it.

No, I have read many cards of that class by that card reader. The card reader does not have/had any problem, And I mentioned that issue above. Anyway thank you.
