How about something like this:
$vols = (get-ncvol W2K12SMB3*)|select -expandproperty name
foreach ($v in $vols){
if((get-ncsnapshot $v|?{$_.Created -gt (get-date).AddDays(-1)}).count){
write-host "volume $v has current snapshots"
}
}
The Parameters can be tweaked like days or sub na for nc for Legacy.
