Hitachi 5K500.B finally available

[MuF]

does anyone have an idea of what that random and odd sound that I'm hearing is? it's not a click or something like that. it's almost like the sound of a drive powering up or down when booting a computer. but the machine is on and actively in use and the HDDs are not set to go to sleep ever on A/C power.

I'd say I hear it 2 or 3 times a day, so it's not a frequency concern; rather a "should this be happening at all?" concern. do any other 5k500.b owners hear this sound? if anyone has insight, I'd love to hear it.

same here. I hear this just few times a day... very rare... it's like BZZZT 0.3s lasting sound like some rapid movement of head or what. HDD is new (6 days old, running 24/7). does anyone know what is it? Im glad I found some info about it, I was afraid I've got failing hdd.

Can you tell me whether the sound is like on of those from here.
My HTS541616J9SA00 is doing these sounds every once in a while and I'm afraid it's getting corrupt.
That's why I'm looking for a new one.

Thanks
