Default HD power management settings will kill drive
I run feisty (beta) on a Dell Inspiron 9400 with a Hitachi HTS541616J9SA00 hard drive. After booting, the drive's power management settings are such that it spins down A LOT. To give you some statistics: the drive is rated for 600,000 load/unload cycles, and after 2.5 months of running Feisty I'm already at more than 56,000 load/unload cycles (and only 150 power cycles), according to the SMART data. At this rate the drive will be dead after 2.5 years, and I don't even use this computer for more than a couple of hours each day. The fix? I have to do:
hdparm -B 255 /dev/sda
and the spinning-down stops. I don't know what certain other OSes do with their drives at bootup, but the current behaviour is certainly deadly for the drive. Worse: nobody will notice, since smartmontools aren't installed by default. I noticed frequent clicking sounds earlier, but I didn't think those were spindowns since I hadn't specifically set the drive into any low-power mode. I only noticed this by accident after I got smartmontools working.
