Thanks for your response, Troll! When I first used my Epson camera I was using SanDisk's first USB/CF Reader(Mod.#SDDR-05a) and was having no problems erasing and initializing my CF cards from the menubar. That was back through the OS7-8 period. Somewhere along the line, that became non-effective and I've been waiting for a new driver and/or procedural info to come forth from SanDisk or Epson to replace the old capability....but in vain! I thought my new FireWire combo HD would solve the dilemma, but it will read the card but ,so far, will not write, initialize or transfer contents therefrom (BusLink DataBanker1394-120Gb)
