Hi,
Sorry for the late response.

Surely won't.
It even solved the problem of the OP, as it did in a few cases I
encountered.

Is NTFS indifferent to fragmentation? Where did you get that idea?
Fragmentation is a problem under NTFS, no matter what Microsoft likes
you to believe.
Problem with fragmentation is simply that parts of a single file are
scattered around the HD, so the heads of the HD need to move a lot
instead of reading the whole thing continiously.
You are not talking milliseconds here.

Huh?
A block (cluster) is often 4K in size.
How many files needed for booting XP up are smaller then 4K?
All files bigger than that are suspect to fragmentation.
But I must add that most of these files were written when the HD was
empty (in most cases).

Well, to be honest I wouldn't know about the registry.
But judging by the former misinformation you presented I doubt you are
right here.
