my maxidas ds708 has become extremely slow and the sd card is almost full so I decided to change to a larger one but when i try to copy the current 4gb card to my pc I get this error autel_3c.tab and it wont go beyond that only gets about 6% copied.  Anyone know how to fix this?

That was my thoughts exactly and that's what I am trying to do but I can't get the vehicle files I need off of the original sd card due to this error. I tried getting them from the pc application but all I am able to get is the software without vehicle info and I shouldn't have to pay $700-$800 just to recover that info unless im not looking in the right place. I have tried to copy the card to my pc several times and come up with that same error.
