Reduced HDD Partition

Discussion in 'Windows XP' started by Beyond X, Aug 27, 2010.

    My computer:
    Intel Core 2 quad, 3GB RAM on ASUS P5P43TD Pro mobo
    OS: XP pro SP2
    System32\drivers\atapi.sys\properties version 5.1.2600.2180
    HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Atapi\Parameters\
    EnableBigLba\0x00000001(1)

    I partitioned a Seagate 1.5 TB SATA harddrive into 100GB for
    OS/applications and the rest for data, both as NTFS. AdminTool/Computer
    Management\Storage\Disk Management shows two partitions of about 100GB
    and 1300GB, both Healthy, as expected. Harddisk Manager (Paragon) also
    shows the second partition being about 1400 GB and active, as expected.

    However:
    Window Explorer's Properties shows that the second partition is only
    about 800GB and almost no free space remaining. (I have used that much.)
    Why is Explorer indicating a reduced capacity? Where is the remaining
    about 600GB hiding? How can I make the whole partition avaiable?
    Appreciate help.

    Have the partitions been formatted? by what program? and how were they
    partitioned? extended, primary etc...

    Evidently your knowledge/experiences are extremely limited. I ask you
    not to play with serious questions.

    Additional Information:
    1. Just in case I updated grivers for this disk, but no change.
    2. Disk\Properties\Quata has been disabled, so there shouldn't be
    restriction in drive capacity usage.
    3. The system has been scanned for malware and cleaned resulting in no
    change.

    Since Window's Disk Manager and Paragon Harddisk Manager show the
    fullest capacity of the partition, I cannot resize the partition. Is
    there a utility software that can display the used (occupied with files)
    and unused (avaiable) spaces separately? (In old times CHKDSK
    displayed a diagram of entire clusters with marks for used and unused
    clusters, which would show whether the partition is a continuous one
    space or somehow internally divided.) In my case "something" is set up
    by Windows XP within the partition that is only seen by Explorer
    mechanism but Disk Manager is blind to it. Question is what it could be
    and how to disengage it. Any idea?

    One more thing that I forgot to mention:
    In Computer Management\Disk Management the volume list shows that 800GB
    for capacity of the second partition, in accord with Explorer, whereas
    Graphical View shows that 1400GB for capacity of the second partition,
    agreeing to Paragon. How does Windows XP discriminate the two ways to
    see the same partition?

    Maybe the entire partition is only partially formatted for use?

    I would use a partitioning tool (I like Parted Magic) to get deeper into
    your disk's layout.
