Hard Drive errors

Tech-Archive recommends: Fix windows errors by optimizing your registry

Hi,

I've been having data corruption issues for a few weeks now. I think I
narrowed the problem down to one of my two hard drives that are configured
for RAID1 on Volume0 and RAID0 on Volume1. These are two SATA hard drives
within the Dell 9200 machine. There are no other hard drives.

When I installed Windows 2003 Server, I supplied the iaStor.sys via the F6
third party RAID driver option.

I installed the Intel Matrix Storage Manager product on Windows.

I’ve enabled the Intel RAID feature on my two 250GB hard drives. The Voume0
is configured for RAID1 (Mirror) and Volume1 is configured for RAID0 (Stripe).

This configuration has worked fine for the first two months, but here in the
third month, I’m running into data corruption errors about every 7 days. I
notice intermittent Windows system event errors often occur. When I run the
disk intensive application “Disk Defragmenter”, Windows posts “iaStor” events
every couple of minutes until the defrag is done. I also notice that the
defrag takes 20 minutes to run when it normally would take a couple of
minutes.

I believe the source of “iaStor” is the "Intel Management Storage Event
Monitor" service.

The problem is I don’t have enough information to determine where the
hardware problem is. Is it the Intel mother board (which holds the RAID
controller), the SATA cables, one of the two hard drives or possibly the
power supply? It’s not the software as I have multiple boots and they all
report errors.

Questions please:

1) Using the event log below, is my machine identified as having RAID
enabled? Or is this event log possible for non-RAID configurations also?

2) Is the hard drive identified in this event log?

3) What is the likely failing component?
