It is called a block (or sector). The size of the block varies depending upon the size of the disk, advanced preferences (the size of files normally being used on that disk), and the filesystem being used. They normally run from 512Bytes to 64KiB. As disk capacity continues to grow, look for even larger block sizes to come :-)
The smallest addressable unit of storage on a disk is called a sector.
The smallest addressable unit on a disk is typically a sector, which is commonly 512 bytes or 4,096 bytes (4 KB) in size, depending on the disk format. Each sector can be individually addressed and accessed by the file system, allowing for efficient data retrieval and storage. In modern storage devices, sectors are used as the basic building blocks for organizing and managing data on the disk.

It all depends on how your disk is formatted.
The smallest storage access unit on an IDE hard drive is a sector.

Yes, clusters are logically part of a hard disk. A cluster is the smallest unit of disk space that the file system uses to store data. Multiple sectors, which are the smallest physical units of storage on a hard disk, make up a cluster. This logical organization helps manage how files are stored and retrieved efficiently.
One bit.
The term "allocation unit" typically refers to the smallest unit of disk space that a file system allocates for storing files. This unit can vary in size depending on the file system and the storage medium, and it determines how space is managed and utilized on a disk. An allocation unit is important because it affects performance and storage efficiency, as even small files will occupy an entire allocation unit, potentially leading to wasted space.
