Fun to see commodity desktop hosts as shipped using elements of Scsi that never appeared in Ata, like Scsi op x04 Format. > I think most people thought then > (and continue to think) that this functionality, > if supported by a drive, is the reason > we have "vendor specific" commands. Hang on a minute. There is a small gap between Optional and Obsolete, but a wide wide wide gap between Optional and VendorSpecific The point of keeping Seek, Read/WriteLong, Recalibrate, etc. etc. Optional is to give device folk a chance of implementing something host folk want in advance. By quietly neglecting to carry forward these commands past the 28 and 32 bit Lba limits, T10 & T13 have in effect made it more difficult than it was for host & device folk to cooperate. I'd think the host folk will scream first: they face the prospect of getting locked into a single source for the vendor-specific commands they need. Among the host folk, maybe the bridge whatever-to-Ata folk should scream first: they can't translate T10 to T13 in the 28 to 32 bit Lba range i.e. not above 128GiB @ 0.5KiB/block. x4402 Pat LaVarre [EMAIL PROTECTED] http://members.aol.com/plscsi/ >>> McGrath, Jim 03/20/02 06:33PM >>> > The people on T13, > particularly the officers and editors, > work quite long and hard > and produce something > of substantial value to the industry. Yes certainly. This fact should Not be in dispute, decidely I hope it is Not.
