Blocks of addresses are organized in concentric circles each divided into "sectors" which occupy a portion of the circle. The address of a certain bit of information is the block within a sector.
The configuration of a disk typically refers to the way in which the disk is set up for data storage and retrieval. This can include the file system used, partitioning schemes, RAID configurations, and other settings that affect how data is organized and accessed on the disk.
The process of marking tracks and sectors to prepare the disk to receive data is called formatting. During formatting, the disk is organized and divided into individual storage units that can be written and read by the computer's operating system. This prepares the disk for storing files and other data.
The concentric magnetic circles that run around a disk platter are called "tracks." Each track is a circular path on the surface of the disk where data is recorded. Data is organized in these tracks, and the read/write head of the disk accesses the information by moving to the appropriate track.

We can burn a disk when it is an re-writable disk even though it has data in it.But when it is an ordinary disk i.e., if it is an only writable disk with data in it,we cannot burn the disk with another data.

If you are using the word "assessing" to read a disk then the amount of data you can transfer to the disk (write) is the remaining available free space on the disk. On the other side of the coin, the amount of data to can extract (cut) is the amount of data that is stored on the disk.
A hard disk acts as a storage device for data. Data is also retrieved from the hard disk. The data that is kept in the hard disk is not erased even when the computer is switched off.
Disk Doctor Labs Incorporated, Iomega Disk Data Recovery, and ACR Data Recovery are three companies that sell disk data recovery. OnTrack Data Recovery and First Advantage Data Recovery Services are another two that sell this service.
A magnetic disk is organized with circles called tracks. These tracks (think of the race track around a field) are the path followed by the magnetic head when reading and writing the signal. The data is organized into short sections, called sectors. This is just a convenient size of data, rather like a page is a convenient size within a book. When you read or write data, you do not need to follow the whole track as it spins, just as many sectors as contained the data you are interested in. On the most modern disks, each track holds a megabyte, more or less, and each sector is typically 4096 bytes. The whole disk may have hundreds of thousands of tracks.
A disk encryption software is used to encrypt all the data on a disk. Once a disk is encrypted, then unauthorized personnel cannot access the data storage in the disk.
Reading a disk involves accessing and retrieving data that is already stored on the disk, while writing to a disk involves adding new data or modifying existing data on the disk. Reading does not change the content of the disk, whereas writing alters the information stored on the disk.
