Managing a Hard disk is known as Disk Management.
In a new HDD, we can’t store the data Directly. Raw HDD is divided into some portions to store the data.
The hard disk is of two types.
- Basic Disk
- Dynamic Disk
Basic Disk : If the HDD in Basic disks, the divided portion of the disk is called as Partition.
Partition is of two types.
- Primary Partition
- Extended Partition
We can create all the 4 primary or 3 primary partitions and one extended partitions.
In the Basic disks, We can install the Operating System.
- Primary Partition: In this partition, we can assign the drive letters and we can format that partition to store the data.
- Extended Partition: In this partition, We can’t assign any drive letters and can’t format that partition. These extended partition is further divided into logical drives where we can store the data.
In a single basic disk, we can create only one extended partition.
Dynamic Disks: If your HDD is a dynamic disks then we can create volumes in the dynamic disk.
There are three types of Volumes.
- Simple volume
- Spanned volume
- Stripped volume
- Simple volume: The minimum and maximum requirement of hard disk in simple volume is one.
If a simple volume is created it act as separate storage unit. The read and write in a simple volume is Normal and there is no fault tolerance.
2. Spanned volume: Minimum requirement of HDD is 2 and maximum is 32.
If the first HDD is full then only it store the data into second HDD.
The read,write speed is normal and no fault tolerance.
3. Stripped volume: Minimum requirement of HDD is 2 and maximum is 32.
In this, at a time it is using both the HDD’s to store the data. Here, it stores the data randomly.
The read, write speed of the stripped volume is faster when compared to simple and spanned volume. There is no fault tolerance
