I have a 40 gb harddrive on my 2378 fvu, and my main Windows partition is 10 gb large. When i highlight all of my files (including hidden files), it takes up about 5.5 gb. However, Windows reports only 600 mb of space available. Whaat the heck happened to the rest of it?

When you right click on the drive in windows explorer -> properties, what does it say?

Does Used space + Free space = Capacity on the drive properties? If not what are the numbers? There is a pie chart there too that should tell you the big picture.

No, it doesn't. I seem to be "missing" about 4 gb of space

If hibernation is enabled, windows will set aside an area the size of your memory... still, that would account for at most 512MB-1GB of missing space for most people.

Another possibility is system restore files. How much space does Windows have allocated for system restore on that partition?

1228 mb for system restore =( Still doesn't account for the amount of missing space..

i seem to have a discrepency as well

for example, if i click on the hard drive in windows explorer, i get 52.0 gb free

but if i open up access ibm and click on "system information" i get 53.338 gb free

so i'm not sure which one i believe

granted, it's not off by 4 gb, but it's still odd

Hmm... 1.2GB for system restore, 256 MB for hibernation, that adds up to only about 1.5GB of missing space.

mrxle3,

How much memory do you have ? Paging file will add up to the lost space on the partition, and if you have left the defaults on, XP assigns a value approx. equal to your RAM size. Check that from My Computer-> Properties-> Advanced -> Performace -> Settings -> Advanced ->
Virtual Memory -> Change.

Also make sure that you REALLY can see all the hidden files. You can have just one file with the HSR attributes set that adds up and is not counted by Explorer. To do this, open a command prompt window (good old DOX box) and :
1. Make sure that you are at the C:\ root ( otherwise type CD\)
2. Type DIR /A:HS /S
this should show hidden system files with their sizes.
3. Repeat the above command with all the combinations of H,S and R to make sure that you havent slipped any , ie DIR /A:H /S and then
DIR /A:S /S, etc. going through H, S, R, HS, HR, SR, HR and SHR.
If you find any abnormally large files these are your culprit , DONT delete them , come back to me first ....

Hope this helps ...

Note: If you double-click on 'My Computer', then right-click on 'IBM_PRELOAD (C:', then left-click on 'Properties', it should give you a pie chart and also show you 'Capacity'.

On my T-42 with a 40 GB HD, my displayed capacity is 35,208,036,352 bytes or 32.7 GB. The hidden 'HPA' or IBM restore partition is not visible to Windows. I believe this partition is about 5 GB in size.

If you've been running Rescue and Recovery, all the backups are in a hidden folder that won't show up in Explorer.

They can easily run to many, GBs.

Jabbar : that's not right. His problem is missing 4G from a PARTITION not from the whole disk, i.e. the HPA will cut-off the 4 or 5G from the very begining before he starts to partition, then once he's partitioned to the sizes he selects they should be wholly available.[/quote]

Open a Command Prompt window and enter the command
dir c:\ /a:s /a:h /s

This will display a directory of all system (/a:s) and hidden (/a:h) files on the C: partition, including subdirectories (/s). These are the files that don't normally show up in Windows Explorer. On my T42p, the total size of these files is 4,081,672,329 bytes (about 4GB). On my system, c:\hiberfil.sys is 2GB in size (I have 2GB of RAM) and c:\pagefile.sys is 1.6GB.

Results can also be misleading if your partition is NTFS and you have compression enabled on one or more directories
