I have a SanDisk Extreme 32GB SDHC memory card from my Nikon D90 and when I plug it into my Windows XP machine it first asked for a username and password, and giving one, it now says 'Not accessible, The directory name is invalid.' It shows as a drive named: canon_memory on '75822e000000'.
Please suggest how I can view my pictures on the computer. I'm trying Nikon Transfer for usb connect, but would rather read the card directly if possible.
