E6430 Win7Pro Can't See SD MicroCard but Linux Partition Can

Greetings.

Subject line says it all. My Win7Pro E6430 can't see any SD MicroMemory Card but it's Linux Mint 18 partition can, even though my Windows side is regularly tuned up and updated by Dell Support Assist and I manually updated with Chipset_Driver_54WK9_WN_3.0.07.44_A04.

Any recommendations most appreciated!
