Dok nove generacije mladih advocacy pingvina bez postede napadaju Vistu raznim FUD-anjem (bez nekog razloga, jer je njihov glavni konkurent u desktop Unix svetu Max OS X, koji smo videli da se prodaje a ne deli dzaba u 2 miliona primeraka za jedan vikend ;-) propustaju da vide balvan... i to vrlo veliki, u njihovim ocima ;-)
Predjimo na stvar... Linux (u ovom slucaju Ubuntu) izgleda koristi vrlo cudne vrednosti za power management HDD-a koji drasticno mogu da skrate vek vasem 'jeftinom' hard disku u notebooku. Windows izgleda koristi daleko konzervativnija podesavanja za power management (i ne pati od idiotskog dizajna fajl sistem menadzera koji je komentarisan na poslednjem citatu dole), dok Linuxovci u ovom momentu pokusavaju kriviti BIOS, HDD vendore - a ocekujemo i da ce kriviti zlu sudbinu uskoro :)

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. As these values clearly show, this issue is of high importance and should be fixed sooner rather than later.

There's a debate going on over at bugs.launchpad.net on whether it's the Ubuntu, BIOS, hard-drive manufacturer, or pick-any-player's fault, but Ubuntu (and perhaps any OS) may be dramatically shortening the life of your laptop's hard drive due to an aggressive power-saving feature / acpi bug / OS configuration. Regardless of where the fault lies or how it's fixed, you might want to take some actions now to try to prevent the damage."
I, naravno - kombinacija sa provereno dobrim Linux dizajnom:
The main problem is a combination of the short spindown time, and something wanting to write out to the drive every 30 seconds or so. The main culprit could be the fact that by default, a files last access time (atime) gets updated on every read, even if that read comes from cache. So when the drive is spun down, it gets spun up even on cached reads (to write out the atime).
Add "-o noatime" to the filesystems in /etc/fstab, and that should clear up the issue.
Hehehe...
Sta reci - no - sigurno cemo brzo da se vratimo na preslusavanje FUD-ova o Visti i zaboraviti ovaj neprijatni trenutak blamaze, bas kao i svaki drugi ;-)
