Well unless you have scheduled chkldsk to run yourself it may be that Vista
has found the disk to have dirty sectors and the drive needs checking
(doesn't mean they are grubby or anything like that, it just means they need
checking for read/write access - so don't panic.) Allow Chkdsk/f to run and
then run defragmenter afterwards. Usually when chkdsk/f is actioned by the
system it checks the drive when you boot.
