I have checked the card on cameras and a friend's computer and know that it works and is not corrupted. Another thing I have noticed is that the card does pop up in the Disk Management utility, but it is unreadable. I do not know what device this is, but it doesn't show up unless an SDHC card is inserted and remains after I take it out, but when I do a restart it has disappeared and it is not there if I insert a 4gb SD card first. One thing that I have noticed is that when I insert the card the Ricoh device pops up, but also responds with an uninstalled PCI Serial Port.

I have tried installing the drivers from the Lenovo KB and my Windows Troubleshooter says all drivers for that device are up to date. I recently upgraded to Windows 10 when installing a new Samsung SSD 850 EVO 500GB and now my internal SD card reader which I think is a Ricoh will not work when I insert a SD above 4GB, it works for smaller cards.
