You certainly got more bang when your disk crashed.  I ran a VAX cluster 
with 15 years with shadowed DSSI drives and never had a disk corruption, I 
replaced members of shadow sets when they died but again I never had any 
issues of corruption and data loss.  Meanwhile I also lived with an array 
of Ultrix boxes and SunOS boxes where I had to clean up disk corruptions 
or do restores from tape onto new disks - usually in the middle of the 
night.  Your work is always done faster if you skip steps.
