chris, as per man hdparm: sudo hdparm -C /dev/sdb1: /dev/sdb1: drive state is: unknown
means the drive doesn't support querying it's current IDE power status so that's fine.. when you ran the command: sudo hdparm -B 255 /dev/sdb1 does the HDD still go into a sleep state? If so, would the follow provide a WORKAROUND (please post the terminal results to this report): sudo hdparm -B 254 /dev/sdb1 ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1222313 Title: 0bc2:2300 [HP Pavillion dm3-1109TU] External HDD goes into low power mode delaying saving by 10-20 seconds To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1222313/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
