[Bug 59695] Re: High frequency of load/unload cycles on some hard disks may shorten lifetime

[Vincenzo Ciancia]

This bug is _not_ fixed for me in up-to-date intrepid with the -proposed
repository enabled. I log cycles and temperature using the script that I
attached to this bug

This morning, I had 135 cycles in one hour. Smartctl reports the
following identification for my disk:

=== START OF INFORMATION SECTION ===
Model Family:     Hitachi Travelstar 5K100 series
Device Model:     HTS541080G9SA00
Serial Number:    MPBDL0XKGB63RG
Firmware Version: MB4OC60R
User Capacity:    80,026,361,856 bytes
Device is:        In smartctl database [for details use: -P show]
ATA Version is:   7

Local Time is:    Mon Jan 12 21:42:35 2009 CET
SMART support is: Available - device has SMART capability.
SMART support is: Enabled

I had to re-enable a periodic (every 5 minutes) use of hdparm -b 200.
Using 254 seems ok to me, but sometimes it seems like intrepid is _not_
setting this value at the right point. I use suspend-to-ram and suspend-
to-disk regularly.
