The logical file system deals with all of the meta data associated with a file ( UID, GID, mode, dates, etc ), i.e.In addition to translating from logical to physical blocks, the file organization module also maintains the list of free blocks, and allocates free blocks to files as needed. The file organization module knows about files and their logical blocks, and how they map to physical blocks on the disk.block # 234234 ), or with head-sector-cylinder combinations. Depending on the system, blocks may be referred to with a single block number, ( e.g. #Simple delay protools 12.4 free driversThe basic file system level works directly with the device drivers in terms of retrieving and storing raw blocks of data, without any consideration for what is in each block.ports ) that it listens to, and a unique set of command codes and results codes that it understands. Each controller card ( device ) on a system has a different set of addresses ( registers, a.k.a. #Simple delay protools 12.4 free software
