Partition in XP

By shiveleytom ·
I am attempting to partition my 200 GB hard drive. I have Windows XP Home. Right now it is only showing 186 GB capacity with no extra space. The help files in windows don't seem to help. Does anyone know the steps to take to partition my hard drive so I have windows on part of it and 2 others for each person's files? I have tried using the boot disk to get access to DOS then delete the partition, create a primary, an extended, and 2 logicals followed by formating all the drives but it didn't seem to work.

update the bios on your motherboard to have 48 bit logical block addressing. If your BIOS doesn't have this feature then all you'll see is what the BIOS can interpret and then report to Windows. Normally with Windows XP Service pack 1 and 2 you get Windows 48 bit logical block addressing support for ATA/ATAPI but again, if the BIOS doesn't support 48 bit LBA then its not reported to Windows regardless if Windows supports 48 bit LBA or not.

Another possible reason is the drive is being misrepresented. check that the BIOS is properly reporting the drive as per the drive mfg specs for cylinder, sector, heads.

A possible fix is using drive overlay software to report the large drive to Windows XP [assuming that SP2 is installed which provides 48 bit LBA for large drives].

Under Windows, 186 GB is about right for a 200 GB drive.

Drive manufactures use 1000 bytes per kilobyte of drive capacity.

Windows use the binary / hexadecimal based 1024 bytes per kilobyte.

This dates back to the early years of PC hard drives. Once one manufacture started using decimal drive capacities, they all switched to decimal drive capacities.

As to partitioning the drive, I don't have a XP Home system at the moment, so the exact steps might be a bit different:

Go to the Start Menu,
Select Settings,
Control Panel,
Click on Administrative Tools.
Click on Computer Management.
Under storage, click on Disk Manager.

Select the hard drive you wish to change.
Right click, and select delete logical drive or partition.

Then, right click on the unused drive space and create an extended partition of the entire drive.

Right click on the unallocated space in the new partition and select create logical drive.
Choose the desired drive capacity.

Repeat to create your desired 3 logical drives.

above is accurate but you won't be able to delete the partition as by the sounds of things windows is installed on that partition so what you have to do is boot off your xp cd to run setup and delete and recreate the partitions via setup

Another option would be to use Partition Magic or something along that line. That way you would not have to reinstall Windows or lose any data you already have on the computer.

Just use Partition Magic! It is a great tool and well worth the small investment, especially for PC techs, sysadmins, and hobbyists. PM is smart enough to allow you to repartition an existing Windows primary partition without fouling it up.

Before you do anything to your partition table, make sure to have a complete backup of your hard drive. The current version of Norton Ghost -- v9 -- with an external hard drive, will do nicely. Hopefully, this advice will help prevent a question about a data recovery service.

Sue T is right.

If you still have WinXP installed, you should buy Symantecs PartitionMagic 8. Then you should defrag your windows partition. Let PM shrink your WinXP partition to a third of it's size. In the free space, create the two new partitions. The manual for PM 8 can be downloaded free from Symantec.
