Will it affect the data stored in the drives?

defragmenting a disk will move the files around so the disk can be more efficient. a hard disk stores data in a physical location and with add and deleting files the drive will store fragments of data to fill in the gaps. over time files become fragmented and it takes the drive longer to retrieve the data. Defragmenting will help to un-fragment data allowing faster data read times. it will not delete any data on the drive

Windows file system FAT32 and NTFS use clusters to store the files in the HDD. Clusters are small data chunks of size starting from 512Byte to 64KByte. A particular file's parts are stored in these clusters. Each cluster has a address so that HDD's Read/Write head can locate a cluster.
Suppose you have a HDD with NTFS partition with cluster size of 4KB. Now if you are storing a file of size 6 KB then actually it will take 8KB on HDD (2x4KB Cluster). The OS keeps the record of these cluster for file so that whenever you or OS access the file HDD's head will read it from those clusters.
For making the Write process on HDD as fast as possible Windows store the files randomly on the free clusters. After some time it takes time to Read a particular file's clusters because they might be not in linear order. HDD's Head takes more time to read a file's clusters because of the randomly placed clusters. This is called fragmentation of files.
Defragmentation is reverse process of fragmentation. A degragment program actually place the every file's cluster in linear order so that they can be access faster.

regulary deleting of data and transfering data from one disk to another creates a mess on the cluster of the hard disk so it just keeps all files in the order.

It was once explained to me that a computer is like a child. It will go and get the file(toy) it needs then when it is done it will stand at the doorway to its room and throw the file(toy) back in not putting it back in its place. Defrag and disk cleanup puts everyhthing back where it goes

DEFRAGMENTation arranges all files accordingly so its easy for HDD's heads to read data.
ur copying and pasting r writting files on Discs scattered.
defragment arrange them in order.
