I haven't quite decided. I'm inclined to just special case it. There's some utility to doing an emulation layer somewhere, but that's probably overkill. Look- we don't want to *encourage* manufacturers to produce this kind of stuff- we'll make an exception in this case 'coz this looks like a *really* nice drive, but let's not make this the rule. > > > I'll ask Onstream if they mind the information going out so if others have > > more aggressive schedules they can try to implement this sooner if they > > lke, but you'd better coordinate with me on this. > > It sounds like you've got slightly more time than me.

What I'm also concerned about is media interchange with non-FreeBSD systems... Was it you who said you have a wad of NT workstations with these drives now? Making sure that the media can exchanged between systems is of crucial importance. -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
