Sender: owner-freebsd-scsi@freebsd.org X-Loop: FreeBSD.org Precedence: bulk How do I querry (and maybe enable) my hard drives for buffered writes? I have (2) supposedly identical ST3610N Seagate 500M drives and the one on SCSI ID #0 seems to run at half the thruput of the other on ID #1. I'm guessing one had internal caching enabled. The answer is mostly acedemic now as those drives are elsewhere, replaced with an ST32550N, but now I'd like to know more about how my Barracuda is configured. Studying scsi(8) suggests that is where the key is but at this time I know enough to know I shouldn't go playing with scsi(8) using random commands. System is a NexGen PCI-90 with Adaptec 2940. -- David Kelly N4HHE, n4hhe@amsat.org, dkelly@hiwaay.net ============================================================= To invent, you need a good imagination and a pile of junk. - Thomas Edison
