I'm running a Raid1 (mirrored) setup preinstalled from the factory on two 320gb drives. W700-2757
The System event log showed an event 9 iaStor on disk0 of my raid, a timeout error.
The drive was automatically disabled but I had to reboot to get the system running smoothly again on a single drive.
Raid technology has delivered for me! There's a problem in the driver software or bios somewhere that still needs to be fixed. I called Lenovo, they sent me a new disk, I plugged it in and during the disk rebuild process, got the same error again. It was too easy. I called Lenovo again, got escalated. My Bios and drivers were out of date, no idea why, the Lenovo Update service isn't working prefectly yet for Windows 7 I guess. I updated:
BIOS (BIOS Update Utility for 64-bit Windows) 2.09-1.07
Intel Matrix Storage Console with Device Driver version 18.104.22.1682

Enabling the Write Back Cache can cause you more problems if you suffer an OS failure. Leave it disabled. That's why it is disabled by default. You want the Write Through cache enabled but not the write back cache.

Thanks, Writeback cache disabled! I was a little disappointed that the sector size was only 512 bytes. On a 64 bit machine one would think that a 1 or 2k sector size would be a more appropriate choice for a default on a disk subsystem that has a data cache. Or is this just because the NTFS hasn't been improved?
