Hello, I recently installed Vista Ultimate, so I'm pretty new to it.
My boot drive is SATA(non raid) with an IDE secondary disk.

Vista lives in a logical drive on the SATA disk; in addition there
is a primary partition and two other logical data partitions.

I walked away from the pc and returned in about an hour.
There was the "safely remove hardware" icon in the systray.

I opened it up to get the details, and it wanted to "remove" the other
partitions on the sata drive. Huh? What's it talking about?

Any idea what that's about? Earlier I had run Windows update
and it offered the Nvidia SATA driver as an option which installed and
is working fine. COuld this be related?

Thanks,
Dave
