P4C800 Deluxe, added 2 SATA drive, non-RAID - now slow shutdown

[NuQ]

I have an ASUS P4C800 Deluxe. It was running happily with my 3 IDE ATA100
drives, DVD ROM, and DVD burner. I added 2 WD 120GB SATA drives, formatted
the drives from within WinXP. Put some data on them all is fine. Fine,
except Windows now takes about 4 or 5 minutes to shutdown. Before I added
the drives, it only took a minute or less.

Any ideas? BTW, I flashed the mobo BIOS to try and solve the problem, but
no luck.

Well, I guess this explains why I haven't been able to finds the answer on
Google. No one seems to be having this problem but me :-(
