Hi
I was thinking the same and I decided to try with another OS just in case
I'm running windows xp for almost all day and it works...no HDD failure...
my HDD is 500GB Seagate ST3500320AS SATA2
and I was running it in AHCI mode
but I had to set it to IDE mode in order to run windows since windows can't run on AHCI
so I'm a little bit confused...it works ok with windows and IDE but crashes on FreeBSD and AHCI...
I'll stay with the windows several more hours and try FreeBSD and IDE

thank you

regards
