Lost space on hard drive

Last response: in Storage

Hello,

Experiencing an odd problem with missing space on a hard drive. Here's the information I have:

The drive is out of an HP Pavilion a1330n computer. It is a Seagate 250gb SATA drive.

Windows XP, SP3

The drive has two partitions: 8.51gb FAT32 HP Recovery Partition, and 224.37 NTFS Drive C

Disk Management Console reports: Capacity is 224.37GB, with 551MB Free Space

With "Show Hidden Files and Folders" selected and "Hide protected operating system files" unchecked,
if I select all files and folders in the root folder, and select properties I get:

37.7GB (size on disk) with 185,912 files

Treesize Free reports:
37.8GB with 185,910 files

Windirstat reports:
37.5GB with 185,910 files

Spacemonger 1.4 reports similar numbers.

Diskpart reports (Volume 2 and 3):

DISKPART> list volume

Volume ### Ltr Label Fs Type Size Status Info
---------- --- ----------- ----- ---------- ------- --------- --------
Volume 0 D CD-ROM 0 B
Volume 1 C NTFS Partition 74 GB Healthy System
Volume 2 E HP_RECOVERY FAT32 Partition 9 GB Healthy
Volume 3 I HP_PAVILION NTFS Partition 224 GB Healthy

DISKPART> select volume=3

Volume 3 is the selected volume.

DISKPART> detail volume

Disk ### Status Size Free Dyn Gpt
-------- ---------- ------- ------- --- ---
* Disk 1 Online 233 GB 0 B


Chkdsk fixed a few things, but the problem remains.

The largest files indicated by both Windirstat and Spacemonger are:
HIBERFIL.SYS and PAGEFILE.SYS (this is to be expected, as there are
no large media files).

If a file were artificially made larger in the FAT, I suppose it would
show up in Windirstat.

I'm thinking of using robocopy to copy the files to a fresh drive, just
to see the results.

I'm open to any ideas here. I suppose I could clone this drive to a
larger one, but I'd really like to get to the bottom of this.

TIA,

Rick

XP uses PAGEFILE.SYS as the swap file for the RAM. HIBERFILE.SYS is to store the system as it was when it enters the sleep mode. Each should be cleared and re-started/re-sized automatically upon shut-down and re-start. You can adjust the pagefile size by right-clicking on My Computer and selecting properties>select the Advanced tab, select Settings, select the Advanced tab, press Change button under Virtual memory. Here you can change the size of the pagefile - MS recommends the XP-managed size.

Thanks for the reply treefrog07,

Those 2 files are a combined 2.5GB, and they are included in the 37.5GB total.

The problem is that the drive is almost full (223GB) but the total of all the files
comes to ~37.5GB. I'm missing 185.5GB somewhere...

I appreciate your input!

hi! use the cacls command line (info in the microsoft knowledge base) to view your system volume information. you probably have massive restore points piled up that you can delete. good luck!

Having similar problems right now with an HP A1330n WD hard drive. Reformatting didn't even work for me.

Run disk cleanup. On the "more options" tab, clcik on "clean up" where it says "you can free up more disk space by removing all but the most recent restore point".

I have a 465 GB Seagate Freecom external drive which is showing only 90 GB free. When I highlight the files shown on the disk and click properties the total is 104 GB. I seem to be missing 271 GB. There are 25 in the recycle bin which ought perhaps to be deducted from this, leaving a missing 246 GB. I have asked disk clean up to dump all but one restore point - as suggested in earlier posts - but this makes no difference. I haven't been able to track down the cacls command line as also suggested. Any advice would be much appreciated.
I have Windows 7 Pro on an Acer Timeline laptop.

"windirstat" is a very useful tool for finding out where your space is being used. You have to turn on the display of "hidden" space for some reason.

Thanks WyomingKnott - this has revealed a mass of backups which I should perhaps have known about but were hidden when I just clicked on the drive in My Computer.
A few deletions and respectability has been restored. Most grateful.
