Hi all, Now some campaniles asked about Removable Media Status Notification feature set of ATA. I believe that this function is overlapped to SBC/MMC command set (Packet) and is incomplete to use in product. So in MMC/Fuji discussion we were concluded that Packet device and its host software does not use this feature set in ATA. MMC has embedded changer model. SBC/MMC have many different write protects or similar media and device combination status. Removable Media Status Notification feature set of ATA cannot cover these items. ATA layer persistent prevent, C/DVD class layer persistent prevent and application layer prevent may conflict each other. I think if T13 group needs to keep this feature in ATA, someone must explain this feature in MMC WG. And T13 group may need to add some descriptions to keep compatibility with SBC/MMC command set. I'm waiting for any commnet. Best regards, Keiji Katata PIONEER CORP.
