Oh, ok.  Didn't seem relevant.  Sorry.

So you don't care that your Linux system will deadlock if a PATA disk
is removed, for instance?  Just an example, one that I've seen happen
a couple of times.  Never seen it with Windows, it just tells you that
the disk is gone.

I'll agree to that one.

I'll have to disagree again.
For instance, SMART monitoring is not available for SATA devices under
Linux, while it is ready, available, working etc. under Windows.  I'm
unsure where those "more options" you're talking about is hiding.

Let's not get into that, then ;-).
