[Qemu-devel] [Bug 612901] Re: Qemu doesn't implement SCSI READ DISC INFORMATION command (0x51) Qemu reports: SK=5h/ASC=20h/ACQ=00h

[Jasper Hartline]

Curious if anyone has any information on this, an idea of if it would be 
implemented, or when if ever.
If it won't be implemented, it would be important also.
