Help, Can't mount SD card

It won't work through the pull down bar. After i pull down and tap mount, it turns on usb storage for a second then unmounts and does the whole "preparing SD card" thing and says usb connected. My SD card window never comes up on my pc.

I can mount through spr though.

What do u guys think?

unplug and reboot the phone

Try to access it my going to Start>Computer> and see if its shown there. If not reboot Droid and Laptop/PC/Mac/iPad haha

ok I reebooted the laptop and it mounts again.

Thanks guys!
