Novell, Inc.' s term for the feATure of their network file serveroperATing system, Novell NetWare, which handles errors in disk write operATions. The OS re-reads every block it writes to disk while it holds the dATa to be written in memory. In the case of an error, the dATa block is written to a spare area on the disk. The feATure lost much of its importance with the widespread use of hard disk drives with built-in error correction and bad block re-mapping. (1997-05-27)
