SD card problem

Hy!

I've buy a Sandisk Ultra II 1 GB SD card. I put in my laptop's card reader
and I push twice by misadventure. So I unplug the card before Vista install
it properly. When I put the card in the card reader, it appears in My
Computer, but when I try to open, it says there's no disk in the drive.
I try to reinstall the driver but still doesn't work. The card is OK. It
still works in my digital camera and on other systems. The card reader is
OK. It works with other cards.
I had the same problem with my mobile phone, but I plugged into another USB
port and Vista install it again and it works. /but don't work on USB port
what I don't install my mobile phone properly before/

Thanks for your advice!
