"The driver detected a controller error on \Device\RaidPort3"

Hello all,

For the last month or so we've had unsual repeating errors on our windows system log:

"The driver detected a controller error on \Device\RaidPort3"

First, we don't even have any devices on raidport3. And second, all controllers seem to be operating accordingly.

We get this error about every 20 minutes and it completely floods our system logs. Again, we don't seem to see anything negative happening on our server but the messages are overwhelming.

Server is running SBS 2011 11.5 (x64) build 17318 with LSI 3ware 9750 SATA RAID Controller.

Any help will be appreciated. Thanks!
