Any Software to Analyze Hard Disk Capacity?

During the past few weeks I have faced the problem of lost some GBs fro
my Hard Disk! My Hard Disk's Capacity is 500 Gbs! However, when I ad
together Program Files, Documents and Settings and any other leftover
they don't reach even the amount of 350 Gbs! So, I reckon that I hav
hidden (lost) some Gbs in my Hard Disk! In the past I used a softwar
that used to analyze my Hard Disk Data i.e. Program Files = 100 Gbs, M
Documents = 120 Gbs etc..
Does anybody knows any software to do this and to recover the lost dat
(capacity) if possible
Thanx in advance!!

Well, that is a commono misunderstanding.

1. Your 500GB (decimal) capacity shows as 465GB (binary) in the system.
2. To get a true count of all the files run WinDirStat ( 'WinDirStat -
Windows Directory Statistics' (http://windirstat.info/) ). Only than you
will have a true count.
3. Finally, up to 15% of your OS partition is used for shadowstorage -
and that you do not see in the above. For a better understanding I have
made this write-up:

With each install and uninstall, Vista writes a shadow (restore point)
of about 1GB - plus one is written each day. For that purpose Vista
reserves 15% of your OS disk partition and allocates/uses it as needed.
Find Command Prompt (in All Programs > Accessories > Command Prompt),
right click on it and Open as Administrator. Into the little black
window type VSSADMIN LIST SHADOWSTORAGE and hit ENTER. It will show 3
numbers:
Allocated - that is the amount that it has grabbed from your OS
partition at this time
Used - this is the amount currently used
Maximum - this is the ultimate amount it will allocate and use
Once you reach "maximum", it will reuse the space deleting the oldest
shadows for the storage of the newest shadows. With e.g. an appr. 200Gb
of OS partition you should expect a maximum of 30GBs that are reserved
for the system and that you cannot use. If your OS partition is larger
or smaller, the shadowstorage will be accordingly (always 15% max.) But
the restore points (shadows) are required the day you need to do a
system restore

PS: If you need to reduce the amount of shadowstorage ( which I do not
recommend), you find the procedure here:

Ok! I did everything as you said and here are the results which as tol
a Hard Disk with 500Gb storage is approximately 465Gb in binary
However, the WinDirtStat shows that the capacity is only 276,9 Gb! Is i
normal or do I miss something (I mean I don'
understand)1659

16595

Here is how your numbers compute
1. total disk space 465G
2. total files 276.9GB (WinDirStat shows the sum off all files/folder
- not disk space
3. allocated shadowstorage 52.
4. Free space (1) minus (2) minus(3) = 115GB - but if you have an
other disk partitions (e.g. a recovery partition), you must subtrac
that from the 115GB . Does that compute

You need to see the efficiency of your data storage. That's where the
missing space usually is.

I don't know what that is supposed to mean: "efficiency of your dat
storage"

I did the math and should be 135.4 Gb instead of 115 Gb that you sai
and which my system shows anyway! I do not now realize where are th
135.4-115=20.4 Gb remaining

Google for "cluster size". Cluster size = smallest amount of space used
for storage on a hard-disk.

If you save a 2-byte file into a 4-KB cluster on your HD, you end up
with mostly empty space beyond the actual 2-bytes worth of data.

Lots of small files will "waste" more storage space than larger files.

Right, my bad. My numbers got scrambled. Forget the 115. It should b
135.4 - is that what is shown as freespace
If your system shows 115 (or maybe I misunderstood what you said), the
the question is whether you have another partition on that disk - mayb
even a hidden partition

Actually, it shows 115 Gb so I think somewhere 20.4 Gb are somewhere i
my Hard Drive ! I do not have another partition, is any other way t
find if do I have a hidden one? Is not the matter that 20.4 Gb will sav
my life but I would like to know!!
Thanx
