This is a bit of a showstopper

So defragging will delete restore points unless the disk has 16K
clusters. The default size is 4K. Therefore problems ahead. Nice one
Bill.

Anybody know a way to non-destructively change cluster sizes on an
NTFS partition?

Vista's defragger won't do that. Many will, except for those that
allow for the smaller cluster size on VSS-enabled volumes - like
Diskeeper, to name one.

But the Vista Restore Point functionality uses Shadow Copy, doesn't it?
Unlike XP and earlier.

I've just read the article, and apparently it doesn't apply to Vista, only
to the various versions of Server 2003.

Looks like we're OK, then. Still a remarkable bug, though.

Exactly, cannot separate the two.

I wish that you guy's think what you post about Vista holds true or not.

What you have posted has NOTHING at all to do with Vista . READ THE MS KB YOU POSTED
It is a problem only with the W2K3 Server versions and only if the following holds true as per below. Also the last copy of the shadow copy is retained and the oldest deleted.


The System Shadow Copy provider uses a copy-on-write mechanism that operates at a 16-KB block level. This is independent of the file system's cluster allocation unit size. If the file system's cluster size is smaller than 16 KB, the System Shadow Copy provider cannot easily determine that disk defragmentation I/O is different from typical write I/O, and performs a copy-on-write operation. This might cause the Shadow Copy storage area to grow very quickly. If the storage area reaches its user-defined limit, the oldest shadow copies are deleted first

Raxco PerfectDisk is supposed to do that, but sometimes the points get
deleted. from reading the MSKB article, no defragger is _totally_
immune.

His (DrTeeth) post on that KB has nothing at all to do with Vista. Read the KB and what it applies to as far as which OS

Some people know what they are commenting about. Then there are those that
haven't got a clue!

Yes, I use Diskeeper and there's no problem.
