A Computer hard drive is formatted into sectors, blocks and bytes, as i understand it, an allocation unit is a number of blocks in a sector, which is dependant on the type of format used, (FAT16, FAT32, NTFS) thus a lost allocation unit, will be a part of the hard drive which has been locked out of the file allocation table as bad or un-useable due to corruption and or the innability to be correctly read from or written to. this is usually done by the routine "CHKDSK" (check disc routine) the file allocation table is part of the enmgineering track on the hard drive and is used by the controller software to track and locate files and ensure that when a file is spread across the disc (fragmented) the FAT (file allocation table, knows where each part of the file is.
as i come from old school drives, the block size was 128 butes of which a byte was 16 bits the number of blocks in a sector was dependant on the hard drive size and the type of format used. i hope this helps.

Equivalent units are a concept used in cost accounting to measure the work done on partially completed units during a specific period. They convert incomplete units of production into a standardized measure that represents completed units, allowing for more accurate cost allocation. This is particularly useful in industries with continuous production processes, such as manufacturing, where some units may be at various stages of completion. By calculating equivalent units, companies can better assess their production efficiency and control costs.
