SATA drive problem under FC6 x86_64
 

I have a Toshiba Core 2 Duo laptop and it has a SATA hard drive in it. I've never had a laptop with a SATA drive in it before.

I have it dual-booting FC 6 x86_64 and Windows XP and when I shut down with XP, I don't have any problems. But when I shut down with FC, there is a wierd "plonk" sound.

It is very similar to the sound when I force a shutdown by holding down the power button.

Anybody encounter something like this before?

I have an HP Pavilion dv5000t with a SATA drive, and I hear the same sound when I shut down. I don't think its the drive, though--I'm pretty sure its the cooling fan and the sound card shutting off.
