Good questions from and . A sudden 30 GB loss is usually either: 1) your main partition lost space to unallocated/hidden partitions, or 2) Windows reserved the space for system files (restore points, hibernation, pagefile), not user files.

Try this, in order:

  • Check the actual partitions. Press Win+R, type diskmgmt.msc, Enter. In Disk Management, do you see ~30 GB as Unallocated or a Hidden/Recovery partition? If yes, and you are on Vista/7+, right‑click your main volume and choose Extend Volume. Back up first if you change partitions. Microsoft’s overview is here: Disk Management overview.

  • If capacity is fine but free space fell, look for big system files on C:\ (enable showing hidden and protected OS files). Common culprits:

    • System Restore / Shadow Copies. On Vista/7+, open an elevated Command Prompt and run:

      vssadmin list shadowstorage

      If it is huge, reduce it (example sets a 5 GB cap):

      vssadmin resize shadowstorage /for=C: /on=C: /maxsize=5GB

      Docs: vssadmin.

    • Hibernation file. If you do not use Hibernate, remove it (admin Command Prompt):

      powercfg -h off

      This deletes hiberfil.sys and frees RAM-size space. Command reference: powercfg -h.

  • Empty the Recycle Bin and run Disk Cleanup (cleanmgr) to clear temp files.

If numbers still do not add up, run a file system check (chkdsk C: /f) after a backup. Post back with what Disk Management shows and your Windows version so the fixes match your setup.

are you talking 30gig spare? or 30gig data? how do you know its missing? hdd space cannot just disappear. what have you changed/added/deleted on your pc, like settings, software, drivers? what operating system you running? release level? service pack?
