How to disable write cache in Windows 2000

Last Modified: 2013-11-14

We have an IBM Xseries 3500 with a scsi raid in place. We keep seeing corruption of data and have tracked it down to write cache being enabled on the disks. I've researched this a bit, and windows offered a fix in sp 3, but we're patched to sp4, and still having issues with corruption. We want to disable write cache, but every time I go to device manager, click on the disk, go to properties, and then disk properties, untick the box, and then hit ok. It re-enables itself. Is there any group policy I can configure to permanently disable this feature?
