default setting of WCE

[Rong-en Fan]

Hi,

I'm wondering what's the default of our da(4) regarding
the WCE (write cache) bit. I see some of my disks has this
bit on by default and some are off. I guess it depends on
the capabilities returned by the underlying device when
probing? In addition, on the same hardware, I found that
Linux has write cache enabled by default... (yes, I have read
da(4) and knows the pros/cons of enabling this).

Thanks,
