I want to zero the whole disk as a certain pattern like 0 or else with
vendor specific WRITE command 0xFD on 1TB SATA Disk in my test. This command
0xFD can support issuing a 1 to 65 block zero pattern to the disk and should
be done about 4-hour on 1TB Disk rather than about 11-hour on 1TB Disk with
SCSI WRITE(10). 

Attached pls see the details debug log on SUSE Linux Enterprise 10 I just
did. As for code, I will send to you in private for it is kind of poor and
confidential. Really sorry for that.

Thanks so much for your input. I think my concern is a specific request but
it's reasonable in real world of SATA domain.
