Windows 7 Do you want to scan and fix SD Card (E:)?

[genandnic]

Every time I insert my SD card, this annoying error pops up on my screen.

Do you want to scan and fix SD Card (E)?

There might be a problem with some files on this device or disc. This can happen if you remove the device or disc before all the files have been written to it.

Scan and fix (recommended)
This will prevent future problems when copying files to this device or disc.

Continue without scanning

I never have removed my SD card while files were being written to it, and yet I continue to get this message. So I've tried scanning the SD card for any incomplete files and it always turns up with no results. Why does it have to waste my time then? The SD card works fine when I continue without scanning it. How can I keep this error from appearing next time?
