Problems formatting SD card in 7.1.1

I purchased a Lenovo Tab 4 with android 7.1.1. Unable to add sd card. If I use a new card (tried several) I get the message "corrupt card - erase and format?" When I click yes, I get a quick pop-up message saying something like "error(some numbers)partition(some more letters and numbers)". If I try with a card that was used in previous android 5 tablets, I get the message "new card detected-set up? Erase and format?' When I click yes, I get the same message as before. If I format a card on a laptop as Fat32 and insert the card, I get the same first message.
