I have a PEG-SJ30 that I was given as a hand-me-down. It appears to be in very good condition and proper working order. I bought two 128MB memory sticks (Lexar) but the unit won't recognize either of them. It says there is no card. I tried formatting in the unit and it says "This card cannot be formatted". I verified that 128MB is the max this unit will recognize and it does appear to be the original style of memory stick (It's not a pro or a Duo). I have a decade of experience with Palm but no CLIE experience and no memory stick experience (all SD and SD/IO), so I can't intuit any further. Can anyone make any suggestions? Thanks!
