This sounds like a good idea! I vote for a counter of "2"... :-)

Also I suggest to mention as clearly as possible, that operating Soft 
Updates with Write Cache enabled is kind of 'out of specs'. This cannot 
work when crashing! (As you stated clearly!) So I'm also voting for 'WC 
disable' for any kind of disks. SCSI-disks don't need it because of 
Tagged Queuing and only those ATA-Disks that *have* TQ can/should be 
operated 'the fast way' - hoping that Soeren gets it working again...
