Will my savegames be deleted if I take out the stick?

Hi I just got a new MS and I wanted to ask if maybe my savegames get deleted or any data can be lost if I take out the odl stick? I ran out of battery once (i believe) and all my saved games were gone!

So, do you believe there is a possibility something like that could happen?

Regards, Luke

no you can interchange Memory sticks as often as you like and not lose saved data

So I'll dare to...

Thank you!
