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. Sam Song
