  • Free disk space miss reported

    Hi all,

    This one's puzzling me a bit.

    In Windows XP Pro, looking at the system drive's (C) properties it shows a major difference in space usage compared with selecting all the files (hidden + system) and viewing their properties.

    I've (hopefully) attached a jpeg of the two windows. I would of expected a small difference maybe upto 8-10GB of something i've missed but not ~30GB.

    I'm a bit puzzled by this and thought it might be an error with the disk. Thus I used "chkdsk c:", it results showed no errors and no bad sectors.

    I'll keep looking at it but am a bit pressed for time at the moment, any one else come across something similar or knows the reason?

    "cmd> dir" shows 70,944,026,624 bytes free

    Regards,

    Re: Is Free disk space being miss reported

    While I don't have a direct answer to your question, it might be interesting to use a space management utility like WinDirStat or SpaceMonger and see what it says. You can then visually dig into which files and folder are taking up the phantom space (assuming that those tools will see it... I'm not sure which API's they use to calculate the space). Alternatively, you could use some kind of boot disk that has a disk space manager on it. I'm sure there's something like that on one of the myriad Linux live CDs. that would seem to get down to the bottom of what is or is not taking up space on that disk since it's not reliant on any of Windows' own APIs that may be hiding something. *insert paranoid glance here*

      Hmm some good ideas there, I'll have to go for the management utilities over the live cd boot options as I don't have physical access to the system at this time.

          That reminded me, the "recycler" hidden folders have a habit of retaining what you've chucked in there. I had one instance where a user had a few GBs of phantom space that wasn't being freed up. Turned out to be the recycler folder not emptying even though the recycle bin was emptied. Had to use a command prompt to delete everything. May be part of the issue... or not.

            Those should of been included in the disk space calculations as I should have been viewing hidden and system files.

            I'll double check when I next work on the system.

                Ok found it. I used Treeview. Seems like a nice program.

                So a bit more details now.

                The system was a Lenovo Desktop.

                The folder causing problems: RRBackups - Part of Lenovo's Rescue and recover, not security tab on properties, and denies access.

                The Application: Lenovo Rescue and Recovery - Your basic backingup & archiving application.

                Any ways, thanks for assisting me in finding the root (not row-t) of the problem.

                Regards,

                R Austin
