Disk partitioning or disk slicing is a way to efficiently use a storage device by categorising or dividing storage space (virtually) unlike the word slicing suggests storage device like HDD is not sliced physically with help of some knife or cutter it is all done in software side with help of disk partitioning softwares like mini tool partition wizard or disk manager.
Let it be HDD or Pen drive or be it SD card a storage device must be formated (partitioned) to use storage space & at least one partition should be present (can have more than one partitions).
Now-a-days when we buy digital disk drives it comes preformated in formats such as NTFS or FAT32 so that buyer (user) is spared of hassle to partition or format it.
But when it comes to advance users who are trying to install operating system like Windows or trying to install multiple OS to dual boot they prefer partitioning it to separate drives on which OS’s important (core) files are stored. Disk partitioning comes handy even to separate work space & private stuff or if u are someone who formats (resets) PC every once in a while for continue smooth working partitioning is best way to save your data because you just need separate drives for OS & data respectively.
Types of partitions
When partitioning, you’ll need to be aware of the difference between primary, extended and logical partitions. A disk with a traditional partition table can only have up to four partitions. Extended and logical partitions are a way to get around this limitation.
Each disk can have up to four primary partitions or three primary partitions and an extended partition. If you need four partitions or less, you can just create them as primary partitions.
However, let’s say you want six partitions on a single drive. You’d have to create three primary partitions as well as an extended partition. The extended partition effectively functions as a container that allows you to create a larger amount of logical partitions. So, if you needed six partitions, you’d create three primary partitions, an extended partition, and then three logical partitions inside the extended partition. You could also just create a single primary partition, an extended partition, and five logical partitions.
You can’t have more than four primary partitions at a time.
How to create disk partitions in Windows OS
- Open the Computer Management tool : you can do this from start menu or by right clicking on My computer icon on desktop & selecting manage option.
- Select the Disk Management tool in left side panel.
- Make some space for the new partition (if not already available) by shrinking a drive & utilising space for new partition.
- To shrink the drive you need to right click on drive you want to shrink in size & select option shrink after that you just have to input the size you want to reduce from that drive.
Select option Create a new volume.
- The New Simple Volume Wizard will appear on screen
- Enter size of new partition (don’t forget to select option to use unutilised space for new drive).
- Give the new volume a letter name or path.
Tada! You have you new disk partition.
I will write about advanced partitioning & disk formats and their importance in later articles.
