1 sector = 512 bytes.</br>

To find actual size of hard-disk, find number of sectors * 512.</br>

## WHY THERE IS LIMIT OF 4 ?
|

## WHY THERE IS LIMIT OF 4?
|
||||
- Because where we store the information of partitions, metadata of partitions, is fixed and of 64 bytes. This information is stored in partition table.
|
||||
- 1 partition required 16 bytes so only 4 partitions can be created.
|
||||
- In 1 MB (2048 sectors) reserved in hard-disk, 64 bytes are reserved for storing this information.
