I created a mirror set via hitting ctrl-E when booting, for the system drive. I then installed Windows 2008r2, and the ESRT2 RAID Web Console 2.
Via that console I created another RAID1 virtual drive using two more drives. Then a third virtual disk as RAID0.
I noticed that the original mirror set has:
Disk Cache Policy: Enable
Read Policy: Always Read Ahead
Current Write Policy: Write Back
The two new VD's I created have these policies:
Disk Cashe Policy: Disable
Read Policy: No Read Ahead
Write Policy: Write Through
I attempted to change those policies, but the drop-downs only contain the current setting - for example, on the "Set Virtual Drive Properties" page, next to "Read Policy" is a drop down - but it only has "No Read Ahead" listed.
I even dropped the RAID0 virtual drive and recreated it using the advanced options - I was not given anything but the choices listed.
Why can I not set these policies?
