This would be the first time a SCSI disk lies about its write caching.
There are plenty of low-cost (i.e. IDE) disks out there having a hidden
write cache, but AFAIK a generic SCSI tool is usable to enable/disable
the write cache. I'd be quite surprised if your disks wouldn't allow
disabling write caching, because SCSI disks are usually targeted towards
professional usage.
