Is this an issue just with Ubuntu or all Linux distributions?

If you are running linux on a laptop using a battery check this out. You have about 139 days before your HD goes. 

?When switching to battery power, /etc/acpi/power.sh 
issues the command hdparm -B 1 to all block devices. This leads to extremely 
frequent load cycles. For example, my new thinkpad has already done well over 
7000 load cycles -- in only 100 hours. That's at least one unloading per minute. 
Googling for "load unload cycles notebook OR laptop" shows that most laptop 
drives handle up to 600,000 such cycles.?
