With this patch, the SCSI layer will be able to correctly send WRITE_SAME_16 to the Hyper-V host. It will not send WRITE_SAME_10: it has been disabled in the driver template. Do you want me to send another patch with these details? > > + {"Msft", "Virtual Disk", "1.0", BLIST_TRY_VPD_PAGES}, > > Is that version field meaningful or is it safe for us to inquire about VPD pages > without problems on older versions? This version is used in all current Hyper-V hosts: Windows 2008 R2, 2012 and 2012 R2. However it may change in future Windows releases. > > -- > Martin K.
