    I have 40 GB SATA hard drive on my system with single partition C. I checked my HD properties and according to it I have only about 6.6 GB empty space left. On the other hand the space used is only about 14 GB. I wonder where is the rest of my HD space.
    I am running xp Home SP2.

    Hi Aigle

    Are you still using Rollback, and do you have a lot of snapshots.

    IF so that could be where your space is.

    You could try this disk viewer for a third opinion.
    http://www.win.tue.nl/sequoiaview/

    Also you probably know this, when companies sell products, they count a gigabyte as 1000MB, when in reality it's 1024MB.

    There's a disclaimer on the small print of the box if you look hard.. It's all a marketing strategy and you're always a couple gb less than what it says. For example, my 120GB HD is really 111.77GB.(or something like that)

    So your 40 gig hd will only have a true capacity of somewhere around 37 gig.

    If as I suspect possible Aigle is using Rollback, then none of the other standard viewers will see anything but the space used by the snapshot he is in.

    Hello,
    By default:
    Page file takes 1.5x ram.
    Recycle bin takes 10% of space.
    System Restore takes 12% of space.
    Hibernation takes 500Mb or so ...
    Mrk

    Ya I am using it. Currently 13 snapshots. But as I heard these don,t take much space. I am not able to find 16 GB space of my HD. Do u think Rollback can eat all this.

    May be I am missing some thing here!

    I have used another utility with similar results. Other fact told by u are correct but its, a matter of about 16 GB that u can,t loose by this way.

    Yes. The snapshot "indices" don't take much space, but if you have a lot of different data in them that does.

    For example you create a snapshot and load 5 gig of data into it. Then you create another snapshot you want to work in but you don't need that 5 gig of data in this new snapshot, so you delete it in that snapshot. If you checked your disk like you did above it would show that 5 gig discrepancy. Data isn't in newest snapshot, but it is still physically on the disk. And if you are working in the later snapshot none of the the disk viewers mentioned would see the files. This is because they are looking for files based on the windows file system.

    Note if you went and just deleted those snapshots you wouldln't see any difference until you ran Rollback's defragger.

    Thanks Peter for the explanation. It,s still not exactly clear for me. I do delete liek this but these are softwares that might not be so big.
    I went to my basic snapshot and it is also showing almost same values. Does it mean I am going to run short of space on HD very soon?
    I defrgmented just now and it shows 7 GB free space now- almost same.

    Hi Aigle

    Defragmenting without deleting the snapshot won't help. Also no your baseline snapshot won't reflect the space either.

    If correct yes you are running out of space. You could boot to each snapshot and check and see what you've got, but it might be tough to tell.
    Actually you might try checking what you have in your baseline snapshot and see how each snapshot compares to that. This might give you a clue to whats going one. If your current snapshot is the valid one, and you don't need what is in the other snapshots you also might consider doing an update baseline. This will of course reset the baseline to your current system, and you'd lose any stuff in the individual snapshots that isn't in the current one. Then you'd know for sure what your disk looks like.

    My current snapshot is of course not good. I will reset my baseline in a couple of weeks, deleting consequently all other snapshots and will see how much space I gain.

    http://www.rollbacksoftware.com/kb/...when-deleted-or-encypted-when-not-being-used?

    I have read the knowledge base and I don,t think that data of my snapshots is taking 16 GB of space. It,s a big amount and the only changes in the snapshots from my basic snapshot are few software installations or change of some settings etc. But of course it will not be clear until I unisntall RollbackRx.
    Ok, when I will reset my basic snapshot, I will uninstall it to see.

    Interesting, but not sure I can really answer. I agree that the .07% is somewhat misleading. By that comparison FDISR would take almost 0 space for 10 snapshots. What you have to remember is if you take a snapshot and add 1gig, take a snapshot and delete 1 gig, and do this ten times, your disk space usage isn't what you started at, but you have used up 10 gig. Only by deleting the snapshot, and defragging do you get that 10 gig back. One of the virtue's of occasionally updating the baseline, IF that suites your usage style.

    I will not take so many snapshot now. As Uu said 10 Giga, I don,t mind that but u can see it is taking even more than that. I really feel that their statement might not be fault technically but it,s sure deceiving that,s really bad. I did not see a response from any Rollback user so far.
    Just wonder if on same system I take same no of snapshots with FDISR, it is going to take more space or less? Any idea?

    With FDISR the calculation is simple. If you are using 20g now, and say you setup 1 gig to be available to all snapshots, thru it's data anchoring, then each snapshot will be 19g.

    In all fairness to Rollback the do state that the .07 number is just the indices, but I agree it is misleading.
