FYI: the card crapped out on me after 3 days. I got a replacement which lasted 3 days also, getting a refund now.
The card showed files, but wouldn't open them, locked up my XP desktop machine on insertion, reformatted OK, but then stopped working soon after for good.
Steer clear of this one.
FWIW, at the time I was having issues with this card, my PQI 2GB worked just fine under the same hardware and other circumstances. No amount of swapping the card reader, etc, would make me think it was anything other than bum card(s).
