Resize Cluster to 16K on the boot drive

Shadow copies may be lost when you defragment a volume

http://support.microsoft.com/kb/312067/en-us

Article ID : 312067

SYMPTOMS
When you run Disk Defragmenter on a volume with shadow copies activated, all
or some of your shadow copies may be lost, starting with the oldest shadow
copies.

After the shadow copies are lost, events that are similar to the following
may be logged in the System log:

RESOLUTION
If the file system's cluster size is 16 KB or larger, the provider can
recognize disk defragmentation I/O and handle it correctly. Microsoft
recommends that you use a 16-KB or larger cluster allocation unit size when
you format the volume if you plan to defragment volumes that are used for
shadow copies of shared folders, .

off Vista DVD though. Once inside, use format <volume> /a:16K
