Thanks for the info- I usually don't really try and program to devices I can't really test, but in this case I've noticed a lot of usage of this device, so I should try and get it right. It really was news to me that fixed block mode goes to 1K above QIC-320- but then, I haven't really worked with QIC for some years. It's not clear to me whether this is a generic standard or not. What I need to do here is to move up the priority list expanding the quirk entries so that drive specific preferred blocksizes and density codes are used (sound vaguely familiar from the old FreeBSD driver, eh?). I'd love to do this all from first principles and standards, but, guess what- that fails to please everyone (well, nothing will please everyone, and I might as well be disliked for something worthwhile like the tape driver than something silly like a Win32 Bulk Emailer...). The other problems you reported, Stephen, are mostly related to the hardwar. The speed issue and the strange densities- the former just *is* and the latter is just pretty much a passthru from/to the device. I'll probably be updating the -stable release streams by the middle of next week with changes here. Which I'll try and fit somewhere within the 7-8 projects I'm involved in (let's see- Fibre Channel Fabric support for Solaris today? Or NT PCI PCMCIA card reader driver? Get the slides for my "common driver talk" to Univ. of Minnesota? Merge latest NetBSD-current into Nasa/AMES MSS3a tree and resolve all the DMFS induced file conflicts? Build a 9 DataDirect CCD (~1TB) and test Matt Dillon's FFS/VM changes on that? So *many* things to do....urp..help!..) -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
