define not special?
Nothing special... And any option I could use would'nt change a thing: the cache is on the disk itself... I did'nt look physicaly yet but according to the docs there's no way to disable it lik I always did on IBM...
I was forced to buy those disk (more expensive, not better)
ISTM that the driver should force it out to the disk, unless the disk is
lying to the driver, or the driver is buggy.
That's exactly what I think: the DISK has a write cache so it's lying to the controler saying data is written when it's only in the disk cache.
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.
