I have a question about atacontrol and sysctl. I thought the write cache on my harddrives is off. sysctl hw.ata.wc tells me hw.ata.wc=0 So, write cache is disabled, i thought... But, if i check my first HD on the first IDE with the tool atacontrol (atacontrol cap 0 0), i will get a different message to that above with sysctl: Feature Support Enable write cache yes yes ... The harddrive is a old 9 GB Maxtor one: 91021U2 Firmware: FA520S60 So, how could this be ? Sysctl tells me write cache is off, atacontrol tells me it is on (first HD on first IDE). I habe switched write cache off in /boot/loader.conf. Could it be that the Maxtor HD has write cache enabled the whole time, and give a sh.. of trying to turning that off ? Thanks for information. asg P.S.: I dont have any problems, i am just wondering... -- Woher soll ich wissen was ich denke wo ich noch nichteinmal gehoert habe was ich sagte ? ----- End forwarded message ----- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
