Right, files must begin on sector boundaries. But the 200k with a 512k
sector example you give will report
Size: 200K
Size-on-disk: 512K
...so that "size-on-disk" is larger than "size". You've got the reverse,
size is larger than size-on-disk so this looks compressed. I'm not sure how
you could get size-on-disk smaller than "size" unless there's compression
involved. Perhaps another NT admin can chime in on this one. My NT
knowledge is limited.

I stand corrected 3.44GB. But no the disk nor data is compressed. I was
under the assumption that if you have a sector size of 512k and have a file
size of 200k the 312k is wasted because you can only have one file on a
sector. But if you reduce the sector size to 256k then only 56k is lost.
Am I wrong? Please correct.

First off, I assume you mean: 3.44GB (three-point-four-four) with a
size-on-disk of 1.38G.
Sector size issues would yield a larger size-on-disk, not smaller. This
looks like your catalog is in a compressed drive, meaning it's 3.44G of data
squished into a 1.38G of space.
This should slow your catalog performance but otherwise, as far as I know,
be acceptable.

OK here we go.
Size:344 GB
Size on disk:1.38 GB
If I read this right there is only 1.38GB of data the rest is wasted.
I think this is because of the number of small files combined with the
sector size on the disk.
If I could reduce the sector size I could recover as much as 2GB of space!!!
Are you folks in agreement with that and if so can I reduce the sector size
without reinstalling the whole system?
