[comp.sys.next] Optical Disk Optimization

nash@vi.ri.cmu.edu (Richard Nash) (07/20/90)

I just looked in my console window for grins and saw the message:
"Jul 18 16:14:55 mendez mach: /Users/nash/OpticalDisk: optimization changed from SPACE to TIME"

This makes me think that the Optical drive can operate in two modes. Personally
I want to always be in 'Optimized for time' mode. I rarely need all of the
storage on a given disk, but I hate waiting for it.

Is there any way to set the mode you prefer?

This is NOT a feature of the optical drive--it is a feature of
the Berkeley Fast File System.  If the system is changing things
on you, you're probably hovering very close to 90% full.

Time optimization is the default on most filesystems; see the man
page for "newfs" for more information and metainformation.
