AmigaDOS Technical Reference Manual AmigaDOS Technical Reference Manual Table of Contents 1.1 AmigaDOS File Structure 1.1.1 Root Block 1.1.2 User Directory Blocks 1.1.3 File Header Block 1.1.4 File List Block 1.1.5 Data Block 1.2 DISKED - The Disk Editor AmigaDOS Technical Reference Manual Filing System 1.1 AmigaDOS File Structure The AmigaDOS file handler uses a disk that is formatted with blocks of equal size. It provides an indefinitely deep hierarchy of directories, where each directory may contain other directories and files, or just files. The structure is a pure tree - that is, loops are not allowed. There is sufficient redundancy in the mechanism to allow you to patch together most, if not all, of the contents of a disk after a serious hardware error, for example. To patch the contents of a disk, you use the DISKED command. For further details on the syntax of DISKED, see section 1.2, "DISKED - The Disk Editor," later in this chapter. Before you can patch together the contents a disk, you must understand the layout. The subsections below describe the layout of disk pages. 1.1.1 Root Block The root of the tree is the Root Block, which is at a fixed place on the disk. The root is like any other directory, except that it has no parent, and its secondary type is different. AmigaDOS stores the name of the disk volume in the name field of the root block. Each filing system block contains a checksum, where the sum (ignoring overflow) of all the words in the block is zero. -

They are mostly associated with the early days of computing, but the technology is still in use. Print speeds of 600 to 1200 lines-per-minute (approximately 10 to 20 pages per minute) were common.

The wheels, joined to form a large drum (cylinder), spin at high speed and paper and an inked ribbon is stepped (moved) past the print position. As the desired character for each column passes the print position, a hammer strikes the paper from the rear and presses the paper against the ribbon and the drum, causing the desired character to be recorded on the continuous paper.
