would be System Restore is allocated its maximum amount of disk space. You can check this by holding down the Windows logo key and hitting the Pause/Break key. Select System Restore tab, settings, and verify the amount of disk space allotted. This can be quite a few Gigs.
My friend is running Windows XP Pro on his laptop. His C disk, the only partition showing in My Computer is a total of 30GB.
He is running out of hard drive space for no apparent reason. I ran a scan with JDiskReport showing his largest files and how much space is being used on the C: drive. Only about 10GB of files were being accounted for, which means that around 10GB of space has just disappeared.
What could explain the missing hard drive space? Any suggestions or ideas would be greatly appreciated.
