Adaptec 5805

Thanks for asking...

Drives are: Seagate ST32000444SS 2TB SAS.
Cache disabled.

I installed the newest BSD drivers 18284, and things seem just fine. I've been hammering away and not a single error yet. Should we leave write cache disabled? Should we re-enable it if driver is found to be stable? I'm really delighted with adaptecs level of BSD support!

1. Your brand of hard drives?
2. disabled if the cache to disk ? (very important)

Cache on _hard-drive_ - off
And when you create a raid do not on on the disk cache.
P.S. seagate disk-s (very smart disks :) ) and at the time of writing does not always correspond to the controller that they recorded a block on the disk - the disk controller finds an error and throws him out of raid. This was my assumption when I off on the disk cache
