I bought the card from pc2buy on ebay and it worked fine after I copied everything from my 2 gig card, but last night I loaded it past 3 gigs and by the end of the day the card lost its format. I've been using cards since the early Ipaq days with the sled, and I've never had a card lose its format, so I'm guessing these don't work.

We'll see if I ever get a refund, although the guy doesn't have much negative feedback. Has anyone on here actually had the 4 gig card work near capacity for an extended amount of time?
