There is a bit of buzz at the moment about
ubuntu affecting laptop hard drives reliability:
https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/59695
If I run the following on my F7 laptop while it's plugged in:
while true; do
smartctl -A /dev/sda |
grep -F Load_Cycle_Count |
tr -s ' ' | cut -d ' ' -f 2,10
sleep 10
done
I get:
Load_Cycle_Count 351489
Load_Cycle_Count 351491
Load_Cycle_Count 351493
Load_Cycle_Count 351495
Load_Cycle_Count 351498
Which is about once every 4 seconds or so.
As mentioned in the bug report I can turn this
off by doing `hdparm -B 255 /dev/sda`
Should anything be changed for the F8 release?
cheers,
Pádraig.
