noun Technical meaning of 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. 1
