Abstract

A storage management device (5, 12) is intended for managing data storage areas (DSB) of a mass storage, such as a hard disk (5), for example,. Associated data storage areas (ID1, ID2, ID3) of the mass storage are concatenated by concatenation data (VD). The storage management device (5, 12) contains backup means (12) in order to determine backup data (SD), before overwriting the concatenation data (VD) with modified concatenation data (GVD), the backup data (SD) identifying the modified concatenation data (GVD) to be stored on the mass storage. If the process of storing the modified concatenation (GVD) is unexpectedly interrupted, the storage management device (5, 12) is designed to determine valid concatenation data (VD, GVD).

Description

technical field

[0001] The present invention relates to a storage management device for managing storage areas of a mass storage through which concatenation data can be stored in a management storage area which defines a concatenation of data storage areas, wherein the associated The information data can be stored on the mass memory, having storage control means for determining the data storage area identified by the concatenated data as unallocated, and for determining modified concatenated data which identifies the unallocated area due to writing to the stored The information data of the data storage area is modified in series, and has buffer storage means for buffering and storing the modified series data, and has writing means for writing into the unallocated data storage area determined by the storage control means Information data, and the first serial sub-area and the second serial sub-area for writing all modified serial data into the management storage area.
