Always use it to be sure the OS don't need to write something on the media else you take a risk to loose something
If you're in read mode (switch on the card) only no worry you can remove it safely at any moment.

I think it depends on your hardware, the internal SD reader in my notebook does not show 'eject' when I right-click the drive. I always watch the activity led and remove the card when the led is off.

Did you loose any data yet or are you just taking precautions?

There's a lot of tools to help you repair FAT,MBR it because writing errors may appear, generaly when you remove the sdcard in a not safe way

Well, since you have the "safely remove hardware and eject media" option (which I don't for my SD drive), I would recommend that you always use it. In case Windows is not complaining, you can remove safely after using the "safely ..." option. In case Windows complains (cannot remove ... message), close applications that have been using the SD card and retry. Worst case you have to shutdown your system...
