Thank you for posting.

I have a Sony Vaio running Vista with 52 of 100gb showing as unknown in WDS.

After disabling the System Restore Points all of the unknown space came back.

I’m having exact same problem as the others, i.e. 50+ GB of unknown data I cannot reclaim. I tried the “chkdsk /f c:” but the process completes without error and without reclaiming my space. I then tried downloading and extracting your LocalSystem file but when I try running cmdassys.exe I never get a command window. I tried the other programs ans with RUNasSYS.exe I see a cmd window for the blink of an eye. Fyi, I booted in safe mode, logged in as Administrator and tried to run it, no help. Any advice on why I cannot get cmdassys to run? Thanks!!! Btw, I have WinXP sp2 build 2600.

maybe there is a way to analize the unknown so it is known.

There might. The biggest “problem” in that sense is that WDS is multi-threaded. Under some circumstances fetching the backup privilege will already do the job and let me look into “System Volume Information” etc.

However, the privilege needs to be enabled for all threads and the user has to own the privilege in the first place. So basically WDS would then behave differently depending on the “context”.

it could be better to just provide a list of things it could possibly be (just so ppl dont panic) and suggestions how the user could fix it. maybe there is a way to analize the unknown so it is known. i didnt know my pc allocated so much (and used it all), obviously others didnt either.

I think in general we can state that this is the single feature that has caused the most grief so far.

It’s likely that it will be default-off in the next version.

more advice would be to check to see if your unknown space matches with the disk space set aside for that disk in the windows system restore settings, found in: control panel/system/system restore/ select disk, “setings”.

if the size set aside is too large make it smaller (12% is default!)
i would advise to leave system restore on because it has saved me alot, even from a virus attack.

i’m having a similar problem. i have a 1.5TB drive and some how 400 shows up as unkown, i have windows xp64 system restore is off no other programs installed other then WDS and localsystem.zip

using localsystem.zip WDS still shows 400 as unknown. when i look at my disk manager, it showed the full size of the drive and that i’m using 415gb. anyway to gain access to this unknown so i can fiigure out whats in it and see why i’m missing a chunk of my drive?

I have 3.6 GB (28%) space on a 16 GB USB drive with U# and portable apps on it.
I used Ubuntu to completely clear and reload the contents but the lost space is still lost.
My best guess is that the lost space has to do with life span of the individual cells on a flash drive. IE the lost space is out-of-order/expired sections.
