How to resolve Hard Disk Full error.

by wxspoon / September 16, 2011 7:37 AM PDT

HP Mini operating Windows XP. Partition Hard Drive 15 GB drive C, 2 GB Drive D. Constantly getting Hard Disk full error on Drive C (14.6GB of 15 GB used). Only have applications, no personal files, pictures, or videos. Can't defrag. Disabled System Restore. Ran WinDirStat and it only shows 8.1 GB on Drive C with 4GB in Windows, 2.5 GB in files, and .8 GB in Program Files. Going to Properties of Drive C from My Computer it shows 14.66GB. Why the disparity between WinDirStat and Drive C Properties? How do I recover the hidden used disk space?

Thanks in advance.

1. The why is simple. WinDirStat may not be showing the System Volume Information folder or other things.
More about that at http://support.microsoft.com/kb/309531 DO NOT CHANGE THIS.

2. My best tips are to turn System Restore off then back on.

And find a better folder/file browser. Gyula's Navigator shows things you may miss and the NUMBERS NEVER MATCH when Windows is running. You may find folk that want to get the numbers to match and beyond the 1,000,000,000 bytes is not 1GB there are log files, temp files that come and go so fast.

Sorry I wasn't clear. I have about 8 GB of applications on my 15 GB hard drive and no personal or data files. How can I find out what is taking up the remaining 7 GB on the drive so I can get rid of some of it and regain some space? Have run Scan Disk and verified that the hard drive is working good with no bad sectors. Turned System Restore off and on with no help.

Thanks

I noted that Explorer and apparently that app didn't help. I did note a "real" file/folder browser and then you reply with something about not being clear. I'll try again. You need a bigger boat.

Uhh, I meant a better navigator.

If you're missing 7 GB between files you see and the total amount used according to My Computer, the most likely option is that it's in the System Volume Information folder (that windirstat doesn't have access to normally).

Two good options now:
1. Use the cacls command to grant yourself access to that folder. Then both Explorer and windirstat will show it. http://support.microsoft.com/kb/309531 tells how (it's different for different editions of XP).
<span id="INSERTION_MARKER">2. Boot from a bootable Linux disk or USB-stick and look inside that folder. I find the 'superhiding' that Windows does isn't active in Linux so that folder and its contents are visible like any other file.
