When I format a new disk to NTFS I am being asked for the cluster
size. Usually I set this to 4096 but some disks seem to have different
sizes.
Now I wonder how I can investigate the cluster size property on a
disk? The disk properties say nothing about this....

if i'm not mistaken you can
simply run chkdsk from a
command window and it
will provide the stats.

From a command prompt (Start -> Run -> cmd.exe), enter the
following,

fsutil fsinfo ntfsinfo C:

Look under "Bytes per cluster". Change the drive letter as
needed.

Good luck

You're correct. That will report the number of bytes per allocation unit. 4096
(4KB) is the max and is the best size to keep fragmenting to a minimum.

Thanks,
this was what I was looking for. I just wanted to check that I did not
use too small clusters...
