Strange 137GB problem on Windows 2000

Hey there,

I have a windows 2000 advanced server computer running with 2 drives in it,
one (the one smaller then 137GB as a boot disk with windows installed on it,
the second one is bigger then 137 GB (200GB).

It's an old computer so the BIOS doesn't support a 48-bit LBA and there
aren't BIOS upgrades that do support it. So I bought a IDE/SATA raid
controller with a PCI slot, after I connected the drive the windows 2000
advanced server installation cd (including SP4) could easilly recognize the
disk at full size so I formatted it into 1 partition. After creating the
registry key 'EnableBigLba' all worked fine and windows could recognize the
big HDD.

But, and now I got quite confused, after copying lots of data unto the disk
about 160GB, windows said there was only 137 GB on the disk and there was
lots of space left (about 50GB).
But that's not right! I put more then 137 GB on the disk! So I summed up all
folder sizes apart to see if the sum of folders was greater then 137GB, but
it wasn't. I counted all the files that I copied on the source HDD and the
destination HDD (the server HDD), but they matched, there weren't any files
lost.

So now I'm wondering,
Is there really 137GB data on the disk so there must be data corruption,
OR
Is windows 2000 giving me wrong information and how should I know when the
disk is full then?

I hope anyone could help me understand what's happening, cause I don't think
it makes any sence.

Yours faithfully,

Erik Hubers

I think you should log in as the administrator and go to settings/control
Panel/Administative Tools/Computer Management/Disk Management

and see what it says on there. You can see the size of the disks and the
partitions and you can even with a right click see what is on the disk via the
Explorer.
That should get you in the mood to tell us what is going on

Yeah, Go to disk management and check out how much space it shows there.
You can try running chkdsk to check the correct free space on the drive.
You can also run streams.exe from sysinternals to check if there are
alternate data streams.

Diskmanager gave me the same information as the disk properties (tried that
already ;) ), size partition 186GB (I lost some gigs 2 years ago), and 137GB
used.
But I already got the answer on another forum, thanks for your help anyway
:).

It's only windows 2000 that's giving me the wrong information, there's
actually more data on the disk then windows show me. So everything works fine
exept the info windows give me.
 
This is weired. I have not heared of such a bug being reported earlier. If
windows is misreporting disk information, there has to be a reason for it.
