 Normally, mounting SD cards works fine. But sometimes, if the SD card
 isn't clicked in quickly and smoothly, mounting becomes a problem. Steps
 to reproduce:

 1. Insert an SD memory card about halfway the SD slot (I'm able to get
 this most consistently with the Edge 512 mb card). Don't click it in all
 the way, but keep it pushed in halfway.

 2. You will start getting pages and pages of the error message:

 ""mmcblk0: error 4 transferring data

 end_request: I/O error, dev mmcblk0, sector 994296"

 3. Click the SD card in all the way.

 4. Try to mount the SD card with "mount /dev/mcblk01p /mnt." You will get
 the error message "mount: You must specify the filesystem type."

 Mounting using the exact same procedure will work fine if you don't get
 the error message from step 2.

 Getting this bug to reproduce can be a little finicky, but it's definitely
 a problem.
