Recently I bought a Hitachi Deskstar HD-250 GB,SATA-300.It also has a SMART support.
But in BIOS setup (towards the end of POST routine) I see that SMART...disabled.
I also have a utility that I downloaded from Hitachi web site.It runs in DOS and its a bootable disk.
It shows SMART as disabled,it allows me to enable it and then after the reboot...same story.Disabled in BIOS and then it also appears disabled in that Hitachi utility.That utility is called a Fitness Test or something like that.I read somewhere online that everything is OK and that in Windows SMART is enabled and its disabled in BIOS to avoid a conflict.Is it so?
When I run in Windows HD Tune I see all the SMART parameters of the drive.
I also read somewhere online that its best to keep SMART on disable because it allegedly makes the drive work a little bit slower.Is it true?
