Last week, I was so excited about the Windows Vista RTM (6.0.6000) that I decided to upgrade. I still have the same Toshiba M400 and got the latest driver for the RAID controler (1.6.12.0) from TOSHIBA CORPORATION.
In addition to have to load it during setup (my previous blog), I was really disappointed when I first booted my system! Vista was simply hanging for 10-15 seconds every 5 minutes or so. I tried to roll back to a previous version of the driver (... the XP driver) and it was even worse: Blue Screen !!

Fortunatly, one of my colleague showed me the trick ... indeed, there is no way to figure this out!
First of all, open your Device Manager panel for the Control Panel. Then navigate to "Disk Drives", right click on the "TOSHIBA RAID LD0 SCSI Disk Device" and select "Properties"

Select the "Policies" tab and check the "Enable advanced performance" - There you go, you now have a new computer running with no hangs at all! Enjoy!

Attached are the new M400 RAID controler drivers.
