I had a simular problem my first using partion magic I screwed up somehow and not only resized the partion but changed it to something like xFAT32 or something like that, the only thing that would see it was FDISK and that is what I had to use to remove it.

yeah, the partition tables are probably screwed up:

1) find an app that can restore your part. tables
2) make backups of what you have and repartition

Another thought. You may be having issues with the large hard drive support with Windows 2000. Read this for more details:

Drives are never the same size as they say. I have a 200GB barracuda and it is 192GB. Big deal.

my computer despcrition says 200 GBs but it only shows 180, the other 20 GB are reserve as a recovery partition, the accessible capacity may vary. that must be the reason why.

On a 200Gb drive 10GB isn't a lot. Generally 5% is the difference on a drive after formatting and such....which means you are right on target. On my 60GB drive it only had 52GB, which is almost 14%! HP said too bad though....they guarantee within a flat 10GB.

i have an 80 GB hard drive and when i checked the actual size it was like 75 or 74 gb so i suppose it is used for emergency and recovery you could call the manufacturer of the hard drive and see if they can help u if no one finds the answer here

it's because of the rounding,

Hard drive manufactures 1 MB is 1000KB

Microsofts 1 MB is 1024KB

so 200GB is 200,000MB or 200,000,000KB and that's what it's labeled as.

Once you format the drive using a microsoft standard like NTFS or FAT32

Your 200GB Hard Drive will be 195GB or 195,312MB

so youve lost 5GB just from formating, then once you install windows it will use say another 5GB for drive information and fat or ntfs table information, also space for system restore and lots of other information.

So in essence your 200GB hard drive is a 200GB hard drive it's just cause microsoft takes so much space for hidden information for windows and because of the way microsoft format a hard drive.

Um. No.

It is because of rounding, but a kilobyte is 1024 bytes because 2^10=1024, not 1000. Microsoft didn't make up a new definition of measuring data capacity.

And that's just incorrect. There are "hidden" files in your Windows folders, but that is just an attribute. They are not actually on a hidden partition or some hidden section of the drive.

System Volume Information folder contains system restore information and it is a hidden folder on each drive. Also recycle bin has a hidden folder on each drive.

That's what i just stated with the rounding, hard drive manufactures go by 1000 and everything else uses 1024
