Whenever I try to put a micro-SD card into the slot on my Surface RT, the card does not show up at all. I don't even get an acknowledgement that some device was inserted (other than the usual sounds). When I look it up in Device Manager, it says that the device is not working properly. What is the problem?

Buy a new SD card reader.
SD cards have gone through several generations from SD to SD-HC to SD-XC and so on, each of which tweaks the protocol and speeds slightly. As a result new cards may or may not work in old readers. If you have an SD card reader that does not support SD-HC or above then you will get exactly what you are seeing.
Particularly old readers may not be able to read cards larger than 2GB. 2GB was IIRC a limitation of the early SD specifications which has since changed.
From SDCard.org: SD, SDHC, SDXC and SDUC Card Capacity Choices
An SD host can only read SD cards, And SD-HC host can read SD-HC and SD cards and so on. SD (non HC) only supports 2GB or less. SDHC supports >2GB but <32GB. SDXC supports >32GB and <2TB.
So the compatibility, and age, of your reader matters. If you have an SD-only reader then you are limited to cards less than or equal to 2GB and can use the "vanilla" SD specification.
