[Bug 160621] Re: running hddtemp as a daemon might cause unnecessary disk activity
I confirm this bug for SATA2 disk! My hddtemp version is 0.3-beta15. I've tried with two pcs, one with Debian Etch and a IDE disk, when a drive is sleeping if I try to get the temperature hddtemp returns correctly: "/dev/hda: ST3500630A: drive is sleeping". The other pc has Ubuntu Hardy and a SATAII disk, I've killed the hddtemp daemon and when the drive is sleeping if I try to get the temperature the disk poweron.. here the log: [EMAIL PROTECTED]:/etc/init.d# hdparm -C /dev/sdb /dev/sdb: drive state is: standby [EMAIL PROTECTED]:/etc/init.d# hddtemp /dev/sdb /dev/sdb: ST3250620NS: 45°C [EMAIL PROTECTED]:/etc/init.d# hdparm -C /dev/sdb /dev/sdb: drive state is: active/idle -- running hddtemp as a daemon might cause unnecessary disk activity https://bugs.launchpad.net/bugs/160621 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 160621] Re: running hddtemp as a daemon might cause unnecessary disk activity
I can confirm this. I nearly went out of my mind trying to figure out why my unmounted ide disk kept waking up after hdparm -y (Bug #180986) until i finally found this. It appears to poll anywhere between 2 seconds and one minute. -- running hddtemp as a daemon might cause unnecessary disk activity https://bugs.launchpad.net/bugs/160621 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 160621] Re: running hddtemp as a daemon might cause unnecessary disk activity
** Summary changed: - hddtemp might cause unnecessary disk activity + running hddtemp as a daemon might cause unnecessary disk activity ** Description changed: Binary package hint: hddtemp - httdtemp might cause unnecessary disk activity when running as a daemon. - It is important for laptop users to reduce unnecessary disk-activity + running httdtemp as a daemon might cause unnecessary disk activity. It + is important for laptop users to reduce unnecessary disk-activity because the harddrive head might be parked or the drive might be spun down. IMHO hddtemp should not need to access the harddisk after starting up unless configured for logging.
