I recently got a PStwo. And trying to set up so I can backup game saves on PC. I brought Datel's Maxmemory 64. Then seen the product Datel's MaxDrive 128. Loaded up the software on PC. Seems to work fine. Loaded up on PStwo Software loads, recongizes flash drive and memory . But when I go to try to backup save files in the maxmemory it backs me to the main menu to select primary device. If I select the maxdrive as primary it shows up fine as main but there is nothing on it atm to use it. Anyone know if its a compatiblity issue or I need to format the memory stick maybe?
