[QUOTE="cychou, post: 921166, member: 107416"] sorry , I just notice that the command from MAC system is : 43 02 00 00 00 00 00 FF FE 80 which is different to from Windows : 43 02 00 00 00 00 00 03 24 00 The 7th and 8th bytes means the allocation Length , so it's normal that different system issue different value. But the last byte (which means control byte) in MAC is 0x80 and in Windows is 0x00 . MMC-6 does not define this byte . But SFF-8090 defines the highest 2 bit of this byte as vendor specific . Any one knows what does MAC require from this ? And What is the diffent between them(0x00 and 0x80) ? TIA. [/QUOTE]
