When plugged into my Mac, my P2 Store lets me mount the P2 cards, but the HD won't show, it says that the disc is unreadable. It shows up in Disk Utility, says it's a Matshita AJ-PCS060 #1 Medai with MBR partition, 3.7 GB, Read Only, no SMART. Can anyone help?
Do you have it set to Mac compatibility mode? There's a button-press combination you have to do, and the light will turn orange or green depending on which mode it's in...
