Hot Fix <storage> {Novell, Inc.}'s term for the feature of their network {file server} {operating 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)
