Hello all,   Katata-san,
Katata-san,
Thank you for posting an example Host side Bus trace data.
 Could you provide us more information of Bus data ?
 1. What ‘s BIOS Mode? Compativility or	AHCI ?	TYPE  UEFI or BIOS?
 2. What’s System name?	Is it ODD Power Down dualing Sus/Res?
 3. What’s CPU?	I or  A or M ?
 4. What Port Drive IRST 9 or 10 or MS ?  How is AN?
There is Ultra DMA Mode 5 supported by Drive PIONEER BD-RW   BDR-TD04 in
Identify ATAPI Pachet Device command. That’s why BIOS set to Drive
mode 5 in Set Future command. It dose not mean no necessary to
innitialization. It is needed to see the case user changed other mode case.
> These are ATA trace files at Power-on and Suspend-Resume of Win7 Home
Premium, 
note PC with BD-writer Drawer drive. 
[Pon-nod-eject-detail.zip] 
SATA spec. specifies that the highest Transfer Mode is Ultra DMA mode 5. So
it 
is fixed value to set. It seems that basically when no medium is installed,
no 
more initialization may be necessary.
