How to use Norton Disk Doctor

Has Norton used it? Not used? You are too weak, here we will take a look at the use of Norton Disk Doctor!

Main interface:

After entering the main interface, we will see the following options:

1.Diagnose Disk ---- Disk diagnostics, relative to disk surface detection It can be called general diagnosis. It can detect almost all non-physical errors.

2.Surface Test ---- Disk surface test, scan the physical surface of the disk to find physical errors It must be the most unpleasant function for everyone.

3.Undo Changes ----I regret the medicine~~ rarely used, I use NDD not hundreds of times, but never used it. Mainly Used when performing incorrect or unnecessary operations during the process of using NDD and causing the problem to deteriorate, but this rarely occurs.

4.Options ----Options. Here You can set some default property options, which will be described selectively below.

5.Quit Disk Doctor ---- Needless to say~~~ Just quit.

-- Diagnose Disk:

After selecting to enter Diagnose Disk, a list of disks appears for selecting the disk to be diagnosed. Select one of the keys and press Enter. To select multiple disks to be scanned continuously in a single task, use the space bar to select (the following is an English prompt).

The general items detected by Diagnose Disk are :

1.Analyzing Partition Table ---- Disk partition table analysis. Disk partition table is usually destroyed by vicious virus, once it is destroyed, you can not use the windows system, and if it is serious, it will lead to the whole The data of the hard disk is damaged. By the way, if you do not perform reasonable partitioning when installing RedHat Linux 8.0, it will cause slight damage to the partition table, which is manifested in windows2000 (for multiple systems) to start and execute any disk operations. The system will become very slow and slow.

2.Analyzing Boot Record ---- Boot Record Analysis. Each operating system is required to write its own boot information to the boot record. After starting, after completing the hardware self-test, the next step is to identify the operating system information from the boot record to load the operating system into the memory. If the boot record is damaged, of course, the system cannot be booted~~

3.Analyzing File Al*** Table ---- is the file allocation table analysis. Perhaps written as a short list, we will feel more familiar, that is, everyone often said FAT. It records the organization of all files on the disk. Br>

4.Analyzing Directory Structure ----Table of Contents Analysis.

5.Analyzing Lost Clusters ---- Lost Cluster Analysis. Files are on the disk in clusters as the smallest unit Too many disk fragments and incorrect read and write operations can cause cluster loss.

The above five items will be analyzed and diagnosed in turn. Once an error is detected, NDD will prompt you. Fix it. It may be very complicated in terms of specific errors. It is not listed here. Generally speaking, the error object NDD will be clearly pointed out. We only need to choose repair, there will be three choices in the error report window. Yes--OK to fix, No--skip the error and continue the subsequent diagnosis, Cancle--abandon this diagnostic task. After selecting Yes, you will be prompted to create Undo File (this fix will be saved) As a file so you can undo the fix). But note I believe that when the disk itself has a potential physical error, it may cause the Undo file to fail! In this step we can choose OK to create, or Skip--fix the error but give up creating the Undo file. When you choose to create, NDD will prompt you. Select a directory to save the generated Undo file.

When this diagnostic task is completed, NDD will ask you if you want to perform a disk surface scan (Begin Test to determine the detection, Skip Test to skip). Don't rush, let's play it~~~

After the Diagnose Disk, all the general logic errors will be discovered and fixed. If you suspect that the hard disk has potential physical errors or regular errors, it is often repeated. Occurs, it is necessary to detect the surface of the disk.

--Disk surface scan

We can either enter the disk surface scan from this prompt or enter from the main interface. The following interface options:

1.What to test: Entire Disk Area --Scan all areas.

Area Used By Files --Scan only used areas.

Suggestions : Scan all areas (default selection )

2.Type of Test: Nomal Test - Normal test, suitable for general conditions.

Thorough Test - thorough testing, it will take a lot of time, it is recommended to return after normal test Use it when you have problems. Of course, if you have enough time and hate trouble, you can use it thoroughly at the beginning.

Thorough Test only on Fridays -- Foreigners may have a thorough system maintenance every weekend. , we can not, huh, huh...

3.Passes: Repetitions -- When encountering an area that is difficult to determine whether an error occurred during the detection process, repeat the scan several times to determine.

Continuous -- Relative to Reoetitions, is a more crude method, not recommended.

It is also necessary to say -- Options.

It should be emphasized that: Under normal circumstances, we do not need to set the default options, so this article does not elaborate on the project inside, interested friends can give me a message, I will give another. OK, first look at what is inside East is coming -----

1.General ----General

2.Surface Test ----Surface Scan Option Settings

3.Custom Message ----Get some OEM information about the system

4.Auto Repair ----Automatic repair

5.Save ----Set the current setting as the default setting

6.OK ----Set the current setting to only use for this diagnosis. Settings.

7.Cancle ----Cancel Settings

Here you can use the Auto Repair settings that you may need. After entering, you have the following options:

1 .Partition Tables2.Boot Records3.File Al*** Tables4.Directory Structures

--The content of the above items has been explained above and will not be described here.

5.Compression Structures -- Compressed drive structure, now rarely used

6.Surface Errors -- Disk surface error

The above 6 items have three options to choose from: Prompt-- Prompt (user chooses whether to fix), Auto--automatic repair, Never--detect only does not fix.

The main thing to explain here is Surface Errors, surface detection is slow, when there are more bad blocks Time Users are also required to confirm the mark one by one (mark the bad cluster to prevent the operating system from continuing to use, to prevent the bad cluster from spreading to some extent). At this time you can set it to Auto to reduce unnecessary waiting. Time
