[PUG] High frequency of load/unload cycles on some hard disks may shorten lifetime
Hallo zusammen, vor ein paar Tagen bin ich darüber gestolpert: = = - http://ata.wiki.kernel.org/index.php/Known_issues: - Drives which perform frequent head unloads under Linux Problem Description Some ATA harddrives perform very frequent head unloads under Linux significantly shortening their lifespans. Root cause The inactivity timer for head unload is configured too aggressively either via ATA APM (Advanced Power Management) feature or other non-standard means. Such aggressive settings are very fragile to changes in IO pattern and under Linux many such drives unload their heads only to re-load them shortly. Note that this relentless unloading/reloading cycle can also be triggered under Windows by installing programs which can alter the IO pattern (e.g. certain vaccine programs which runs in background). = = - http://www.thinkwiki.org/wiki/Problem_with_hard_drive_clicking - https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/59695 - https://bugzilla.novell.com/show_bug.cgi?id=386555 Vielleicht interessierts/betriffts jemanden..
