Re: Setting Standby Mode for ATA Disks

Under such circumstances, the drive may take as long as 30 sec- onds to respond to a subsequent disk access, though most drives are much quicker. The encoding of the timeout value is somewhat peculiar. A value of zero means off. Values from 1 to 240 specify multiples of 5 seconds, for timeouts from 5 seconds to 20 minutes. Values from 241 to 251 specify from 1 to 11 units of 30 minutes, for timeouts from 30 minutes to 5.5 hours. A value of 252 signifies a timeout of 21 minutes, 253 sets a ven- dor-defined timeout, and 255 is interpreted as 21 minutes plus 15 seconds. I googled but I did not found anything like this for FreeBSD :/ ATAidle (http://www.cran.org.uk/bruce/software/ataidle.php and sysutils/ataidle in ports) does this. Unfortunately due to a site redesign, the page seems to have been dropped from the google results; I'll have to add the keywords back in so it gets listed again! -- Bruce Cran ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]

This, in turn, appears to have caused the box to lockup/panic (can't remember now) so I had to make a cron job that wrote to the disk every minute to stop it from spinning down! I would love to know if there's some tool which can be used to just turn this behaviour off completely! Did you try to turn it off in BIOS? -ip -- In a family recipe you just discovered in an old book, the most vital measurement will be illegible. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to [EMAIL PROTECTED]
