Thanks for the suggestions. The -I command prints out a bunch of stuff including: Standby timer values: spec'd by Standard, with device specific minimum I tried setting -B to 1 and and then set -S to 5 minutes. Also, -B 255 and then set -S to 5 minutes. No luck with either. These drives want to keep running. One thing of possible interest: The -B command printed the following message: /dev/sda: setting Advanced Power Management level to 0x01 (1) HDIO_DRIVE_CMD failed: Input/output error I would guess that the first line came out just before hdparm tried to do the set, and the second line indicates that the set failed. Perhaps -S is failing too, just without the diagnostic? All of the above using 2.6.22-gentoo-r5 I have not yet tried 2.6.23 as suggested by Mark Lord. --- "And he puzzled three hours, `till his puzzler was sore." from "How the Grinch Stole Christmas" - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
