How to partition a hard drive in windows

Sometimes it is necessary to create a partition on a drive.

With Windows Vista and Windows 7 , this process can be simplified quite a bit. It is now possible to create a partition without needing to format the entire drive.

Before you begin please read this precaution.

This process while not particularly dangerous , should not be attempted if it is not truly necessary. If the power goes out during this process or if your computer freezes , you will probably need to format the drive to regain functionality.Therefor I recommend all important data which cannot be replaced be stored on a different drive during this process.

Okay , lets get to doing. To be able to shrink or partition a drive , you will need to free up some space on the drive from which you want to create a partition. The free space should correspond to the size of the partition you want to create.

After doing this , you will need to defragment the drive.

To do this , go to to “My Computer” , right click on the drive you wish to create the partition from and select properties. Then select Tools and Defragment.

After the defragmentation is done , select start and go to “Control Panel”
No open “Administrative Tools “ and select “Computer Management”
Then select “Storage” and finally select “Disc Management”.
This should bring up the following screen :

The graphs each represent a drive or partition connected to your computer. In the graph , additional information is displayed about the drive including it’s Format , Size , Label and Drive Letter.

No right click on the drive you want to partition and select shrink. Windows will then determine the space available for shrinking. Select the size you want to make the partition and select shrink. This could take a few hours depending on the size.

There is no process bar, so just leave the screen to complete. Once done , this is what you should see :

Right click on the new partition and select new simple drive and select the max space available for the simple drive. Also select the drive letter that should be assigned , on the next page , select the formatting (default formatting is normally okay) and the disc label and finally select finish.
Your new partition is now available in “My Computer”.

Please remember to rate this tip if you found it to be helpful.

Kind Regards

Tecra A11 can't see all of 3TB drive

Support for Disk Drives Beyond 2.2 TeraBytes (TB) and 4K Advanced Format Sectors

Most legacy systems built before 2011 have a traditional PC BIOS. This type of BIOS uses a Master Boot Record (MBR). The MBR Partitions can define a disk drive capacity up to 2.2TB. Windows operating systems that boot from an MBR are therefore limited to 2.2TB per MBR. A 3TB disk drive in a legacy BIOS and Window system will need a DiscWizard device driver to access the full capacity of a 3TB disk drive. Two partitions will be necessary because of the MBR limitation. The device driver mounts the capacity above 2.2TB with another MBR which looks to the system as a second virtual "physical" device.
GUID Partition Tables (GPT) can define drives larger than 2.2TB. You can use GPT today on any Windows 10/ 8.1/8/7 and Vista system as a non-booting data drive. Windows can only boot a GPT partition on a new type of BIOS called UEFI.
UEFI BIOS desktop systems are new since 2011. Windows 10/8/8.1/7 64-bit and Vista 64-bit operating systems support booting from UEFI and GPT without the need of a non-Microsoft device driver. This is the Windows native solution for booting a 3TB drive to a single partition.
Quick facts about Windows and 3TB drives:

  • Windows 10/8/8.1/7 and Vista support GPT 3TB single partitions
  • Windows 10/8/8.1/7 and Vista can only boot GPT on systems with UEFI BIOS
  • Windows 10/8/8.1/7 and Vista can mount a GPT non-booting data drive
  • Intel RST device drivers before v10.1 do not support 3TB disk drives
  • Windows systems with Legacy BIOS and MBR boot drives are limited to 2.2TB partitions
  • Windows XP does not support GPT
  • Windows XP sees a 3TB drive as 800GB on boot or data drives
  • DiscWizard software can install a device driver which opens the full capacity of a 3TB. You can use it to create a second partition for the capacity above 2.2TB

I want to do partition of my hard disk.So please help me

You need to partition your hard drive before you install an operating system on it. If you boot off your windows CD and your hard drive has a partition already you will get a screen that prompts you to format it. You can also dellete the partition and make a new partition. AT that time you can select the size of the partition you want to make and creat multiple partitions. If you choose you can creat one smaller partition from the space available for you to format and install windows on and format the rest of the available space later on after windows is installed from the Administration Tools in control panel.
