1. Volume Shadow Copy Service

Volume Shadow Copy Service， VSS has the function of quick data back-up and recover, and it adds snapshot function through volume manage module; After that, it could create the Image on the basis of Point-In-Time, therefore, the quick back-up and recover of data could be realized. From that, we could know VSS has considerable read and read-in operations to hard-disk, which certainly aggravate the burden of hard disk, so the longevity of hard disk will be influenced as time passes. Press ?Start + R? key combination, and in the window input ?services.msc? and press ?enter? to open ?service? dialog box, and find ?Volume Shadow Copy? in the right window. Next double click ?Volume Shadow Copy?, in the following window change the system default ?automatic? into ?disabled?.

2. Compression and Index Files

Some net friends will ask, ?Do the compression and index files harm to the hard disk?? Yes, they really could influence the longevity of hard disk. Why? You can understand after you read the following section.

If you want to cancel the compress and index function, please right click the corresponding disks or files, confirm the tab as ?normal? in the pop-up dialog box, and then cancel the option ?compress this drive to spare disk space? and ?create this drive index to quickly search?. If the user installs double systems (for example: Windows Vista and Windows XP), the partition which XP locates is the main activity partition, so Vista system has not two checkboxes in the above right-click menu.

3. System Search

The system search is related with the above file compression and index. When the system compresses and indexes a huge file, it needs to read the hard disk frequently with numerous data; moreover, when these operations are finished, the system will again search suited target files to compressed and indexed files if the user carry on search operations, so it is equal to the repeated ?converse operation? of hard disk.

Aiming at the above analysis, we suggest canceling the index file search to avoid the ?seemingly methodic? search to hard disk every time.

Open Windows explorer, click ?tool? →?folder option? (if you can not see ?tool?, please press ?Alt?), in the pop-up dialog box please switch to ?search? tab. In the Vista default setting, only there is the index for file, the file and content could be searched, but if there is no index in advance, the Vista only compares the filenames and finds whether the filenames contain the search option or not. It is no doubt to reduce the search efficiency of this search method, and aggravate the burden of hard disk.

4. Disk defragment and system recover

Many friends, who have some experience on computer, know that the damage from disk defragment and system recover to hard disk is not only in Windows Vista system. However, in Windows Vista system, this problem is still existent, so we shall not ignore it.

Frequent disk defragment has no benefit but damage to hard disk. Disk defragment must analyze the bottom of hard disk and judge which data is movable and which data is immovable, and then sort the files. Before the sorting of hard disk data configuration, it continuously and randomly reads and reads-in the data into other partition, and moves the data into the suitable position. All these operations greatly influence the longevity of hard disk.
