Big SD cards

Zawinski reports trouble with a 4GB SD card and a Treo 700p gadget. I am not very surprised, although for other reasons. Earlier this year, I was offered a Qtek S200 Windows Mobile PDA, and I transferred a 1GB Mini-SD loaded with photos, Stone Roses and Steely Dan songs to it. Within the week it had somehow managed to destroy the card and everything that sailed in it. Not the gadget I had before, nor a HP 6915w, nor a USB cardreader in a Mac could even detect the card's presence. Caveat emptor.
