I added the SD card to the laptop and when it showed up in windows, it shows more drives. i got my local hard drive and my SD card, it shows up like it's more. I even formatted the card but still shows like there is other cards.
If you see several blank drive letters, that could just be the card reader options.
You should post a screenshot of your My Computer and what you see there for drives and run Disk Manager and post a screenshot of that.
