[quote author=“rgriffy”]woah, I have never heard of those 2 sided ones. My memorex just has a switch to lock it. Wouldn’t it be easier just to buy a standard 256mb? I saw a SanDisk 256 for $50 at my local Costco.
not really 2 sided…its just that the old (regular) memory sticks have a max capacity of 128 meg somewhere in the system…so when they (sony and lexar and memorex…) found out how to create the higher density sticks(i.e. mem stick pro), they weren’t compatible with the older cameras and clies. this is just like 2 128 meg sticks in one physical housing, with a lil switch to change which one was being used…
all in all, it is just a workaround so the older devices could now have 256 meg sticks even with out technically being able to handle them.
