not sure, ultimatebootcd , as it has been suggested, may have some answers. For
reference, just get the drive model and get the full specs from the
manufacturer's site.
You can also peruse hardware testing sites such as toms hardware and others for
tests on that particular drive.

Advertised sizes are for unformatted media. Each filesystem will use different
amount of physical resources (sectors in the disk) to hold its metadata, so
that will of course vary. I suppose you can always use the disk in raw ...
using dd or some other clever tool you may devise... :D let me know how it
goes :)
you may be able to increase the amount of available space (of course, depending
on the filesystem used) by modifying the block size, but that will usually
affect the number of total inodes (or equivalent in NTFS / others) available...
man tuning should have a section on this, as well as your filesystem of choice
documentation (eg, man newfs in BSd, man mk* in linux , NTFS docs @ MSDN )
