sector
collection of related data stored on a hard disk
Data can be stored on floppy disk, hard disk, memory stick, CD or DVD.
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.
Either delete it, or physically destroy the disk.
Data can be stored on a floppy disk, since that is what they are designed for. As for whether it can be "received" on one, that is a pretty vague question, as it doesn't address HOW the data is received.

MS-DOS views the data stored on disk as a stream of BYTES. Chapter 11: MS-DOS InternalsPg: 278Book: Operating Systems
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.
The amount of data that can be stored on a disk depends in part on the File System used. Common types are NTFS, FAT 32 and FAT 16.
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.
