It looks like WD BEVT-series was not mentioned here and the kernel.org is still down. I just noticed huge Load_Cycle_Count on the WD1600BEVT-80A23T0. It almost reached 300 000 when I stopped it (299 252 to be precise) with hdparm -B 255 /dev/sda -B 254 didn't help, it just _ignored_ it.
Power_On_Hours is 2771 and that gives an average of 107 cycles per hour. Which is still very small compared to what I've heard today: it parks every 3-6 seconds (!) on the battery. I didn't read all the comments (there is way too much of them) so if there was a better fix then disabling APM at all, please inform me. FYI: it's an Asus T101MT notebook. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/59695 Title: High frequency of load/unload cycles on some hard disks may shorten lifetime To manage notifications about this bug go to: https://bugs.launchpad.net/acpi-support/+bug/59695/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
