SD with problems?

Should definitely be a problem with the card reader.
I bought an external reader I put it in the I7 and does not leave me any error.

This is the final result of the test:

Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 24.4 MByte/s
Reading speed: 27.1 MByte/s
H2testw v1.4

This is strange , it is the first time i encounter this kind of problem .
