把永久删除了的文件恢复（Restore permanently deleted files）

After you delete the error, as long as you do not write the file

to the partition of the deleted file, there is also a chance

to recover the deleted files. But I can't guarantee full

recovery. Now more data recovery software, such as:

EasyRecovery, Pro, FinalDataEnterprise20, etc., here I

recommend the use of EasyRecovery Pro this software. At the same

time, I'll introduce the data recovery steps in two cases,

WINDOWS and DOS. Hope to be of some help to you.

In the process of daily use of computer, everyone may encounter

errors, delete data mistakenly formatted hard disk partitions

and other difficult cases, it might even be deleted the hard

disk partition. So, once that happens, how do you recover the

deleted data?

Restoring data in Windows

If the user is in operation accidentally deleted some files,

such as Word files, text files and so on, or just mistakenly

formatted non system partitions, and Windows is running normal,

then the data can be recovered by EasyRecovery Pro software.

Note: Note: if you need to install the software to retrieve

accidentally deleted files on C, it is best not to install

EasyRecovery Pro C, otherwise it will affect the file system

on C, the bad data recovery.

1. restore deleted files

After you start EasyRecovery Pro 6, click the "Data Recovery"

button on the left of the main screen, and then click the

"Deleted Recovery" button in the window on the right.

After a brief scan, the program requires the user to select the

partition where the file is deleted, and then you can enter the

file to restore the file name and type on the right side of the

"File Filter" column. The program defaults to finding all

deleted files so that you can find all deleted files and

generally use the default values. Note that if the file has been

deleted for a long time, it is recommended that the check box

before "Complete Scan" be selected so that the chances of

success are greater.

When you click next, the program starts scanning the partition,

and finally pops up a list of files. The window with the

"Explorer" almost, users need only in the list to find the need

to restore the files and play "tick" can be.

Note: the deleted file is found in EasyRecovery Pro, the list

of files with the original file name may be different, so need

to find the file recovery to a certain patient, according to

the file name and file types to determine whether you need to

restore the files. In addition, after you select a file, you

can also click the "View File" button to view the contents of

the selected file, which is very useful for finding text files.

Select the file that needs to be restored and click the "next"

button. The program asks for a directory to store the recovery

file. Note that in order to restore security, it is recommended

that the recovery data be stored in other partitions (such as

files that need to be recovered in the D disk, which can be saved

to the E disk). Click the "Browse" button behind "Recover to

Local Drive", and select the target directory in the pop-up

window.

Note: the deleted file is found in EasyRecovery Pro, the list

of files with the original file name may be different, so need

to find the file recovery to a certain patient, according to

the file name and file types to determine whether you need to

restore the files. In addition, after you select a file, you

can also click the "View File" button to view the contents of

the selected file, which is very useful for finding text files.

When you select the directory where you want to save the

recovery file, click next, and the program will return the

selected file to the set folder.

2. restore the data on the wrong formatting partition

After you start the program, click the "Data Recovery" button,

Then click the "Format Recovery" button in the right window,

where the program asks the user to select the partition that

needs to recover the data.

Note: if not only formatted partitions, but also changed the

partition format (such as from NTFS format to FAT32), must be

in the choice of "Previous File System", it will choose the

partition format before the partition format, the only way to

have a good recovery effect.

When you click next, the program starts scanning the partition,

and then pops up a list of files that shows all the data you've

found. Now only need to select the need to restore the files,

then select a directory used to store data, the specific

operation and front undelete files are the same.

Restore data under DOS

In case the user deletes a system file and causes Windows to

fail, how do you recover the deleted data under DOS?

1. make EasyRecovery Pro first aid floppy disk

In this case, through the EasyRecovery Pro DOS to solve the

problem of emergency floppy disk: first find a computer

installed EasyRecovery Pro, start EasyRecovery Pro, click the

"Data Recovery" button, then click on the right side of the

window in the "Emergency Diskette" button, when the rescue disk

wizard window, insert a the floppy disk in the floppy drive,

then click on the "Continue - Yes - Start - Exit to determine"

button to complete several first-aid disc.

2. restore data under DOS

Enter the BIOS settings for the computer that needs to recover

data, set the first boot device to floppy drive, and then boot

the system into the DOS version of EasyRecovery Pro using the

first aid disk. After entering the main interface, click the

"Next" button, after a scan, there will be a hard disk partition

display window, where the selected data needs to be restored

in the hard disk partition.

When you click Next, you go to the settings window where the

user can choose the mode of recovery and generally use the

default value, so you can click Next directly". After that, the

software will pop up a prompt window, click the "OK" button

directly, then go to the restore settings, select the window.

After selecting the files that need to be restored, click the

"Browse" button behind the "Destination" column, and set up a

directory to store the recovered data. Note that the recovered

data cannot be stored in the partition where the data itself

is located.

When you have finished setting, click the "Next" button, and

the program pops up a reminder window that saves the report.

When you click "No", the program returns the selected file to

the specified place.

The DOS version of EasyRecovery Pro does not have an excessive

number of function buttons, and the method of operation is the

same whether it's restoring data or restoring the data on the

wrong formatting partition.

Recovery of deleted partitions and data

Sometimes, when the user is ready to re partition the disk, when

you delete a few or all of the partition, it suddenly found that

there are some data is not backed up, at this time what should

I do? In this case, Acronis RecoveryExpert can be used to solve

the problem.

Installation of s RecoveryExpert

Acronis RecoveryExpert is a commercial software, currently

available online is basically a demo version, part of this

version only allows users to experience the software, but not

really so to recover the data, through the software to recover

the data on the partition and partition, must use the

full-featured commercial version.

Acronis RecoveryExpert installation is relatively simple,

enter the installation wizard, just prompted to enter the

product installation sequence number, select the installation

path can.

Acronis RecoveryExpert has a more powerful function, users can

use the floppy drive or recorder to make a floppy disk or CD-ROM

version of the Acronis RecoveryExpert rescue disk, so that even

if the user cannot access Windows,

也能直接用急救盘来执行Acronis recoveryexpert，从而达到恢复

误删除硬盘分区的目的。

在安装Acronis recoveryexpert时，当出现是否创建急救盘时，勾

选“是的，我想创建可启动救援媒体”。

点击“下一步”之后，安装向导会自动检测当前电脑是否有软驱和刻

录机，对于一般的用户而言，大多只有软驱，因此可以在该窗口中选

中软驱，然后执行下一步操作，此时安装向导会提示用户准备好3张

空白软盘。根据提示依次插入3张软盘后，这个软盘版的急救盘也就

制作好了。

对于有刻录机的用户，也可以选择创建光盘版的急救盘。当Acronis

recoveryexpert检测到刻录机之后，选中该刻录机，然后插入一张

空白的刻录盘，确认之后，Acronis recoveryexpert会自动将相关

文件刻录到光盘中，并且这张光盘还具备引导功能。

2。在Windows中恢复误删除的分区

如果用户只是误删除了除系统分区之外的几个分区，还能进入

Windows的话，那么可以在该Windows中安装好Acronis

recoveryexpert之后，启动Acronis recoveryexpert，在点击“下

一步”之后，程序会自动扫描当前硬盘，如果确实有分区被删除了，

那么会出现两种修复方式--“自动”和“手动”、“自动”即可一般

用。点击“下一步”之后，程序便开始扫描硬盘，经过一段时间的扫

描之后，程序会将搜索到的已删除分区显示在列表框中（图10）。

点击“下一步”按钮，此时程序会自动将搜索到的分区按照未删除前

的状态进行排列。后面的操作比较简单，只需连续点击“下一步”即

可。当删除的分区被恢复后，分区上的数据也随之恢复，跟没删除分

区前一模一样。

3。在DOS中恢复误删除的分区

如果利用分区软件将硬盘中的所有分区都删除了，那么此时可以通过

事先制作好的Acronis recoveryexpert急救盘来恢复误删除的分区

--利用急救软盘或光盘引导系统，自动进入Acronis recoveryexpert

的操作界面，该界面及操作方法与Windows中的操作方法是一模一样

的，因此用户很快就能将误删除的分区恢复好。

提示：虽然Acronis recoveryexpert可以恢复误删除的分区及分区

上的数据，但要达到这种效果，前提是用户没有对硬盘进行重新分区。

如果用户在删除了所有分区后，又对硬盘进行了重新分区，那么

Acronis recoveryexpert就无能为力了。

另外，前面说过EasyRecovery Pro可以恢复误格式化分区上的数据，

但要获得好的效果，必须得保证该分区在格式化之后没有再写入数

据：格式化硬盘时，计算机也只是将根目录区清零。由于删除与格式

化操作只是在文件名或根目录名上做了一些手脚，对于文件的数据部

分丝毫未动，这样才给文件恢复提供了可能。如果在删除文件之后又

对磁盘进行了写操作，那么新文件有可能会覆盖被删除文件原先所占

据的硬盘空间，那么该文件就不能成功地恢复了。

这也就是为什么当用户在使用鬼恢复系统时，如果误将镜像文件恢复

到了错误的分区（例如本来要恢复到C盘，却因误操作恢复到了D盘），

此后想找回D盘原有数据将会非常困难的原因了——D盘不仅被鬼格

式化了一次，还写入了大量的数据，因此原来D盘的数据基本上都被

覆盖了，

At this point, it would be difficult to retrieve the data.

Give you some information to see if it works:

Data recovery of hard disk

1, error formatting the recovery of hard disk data

In the DOS version under the condition of format in the default

formatting operation have been established for the restoration

of the disk format information, the disk is actually the DOS

boot sector, fat partition table and directory table to copy

all the contents of the disk in the final sector (behind because

the sector is rarely used), and in the data area the content

does not change. We all know that in the DOS era, there was a

very nice tool, UnFormat, that can restore disks that are

cleared by the Format command. If the user is using Format

command to format a partition under DOS, try using the command.

However, UnFormat can only restore local hard drives and

software drives without restoring network drives. The UnFormat

command can also fix and build a broken partition table on the

hard drive, in addition to the reverse formatting feature

above.

But it sounds a bit UnFormat has been "unable" method, and then

use it to restore formatted partition has been somewhat out of

date, we can use a variety of data recovery software to recovery,

such as the use of Easyrecovery 6 and Finaldata2.0 recovery

software can perform data recovery work to facilitate the. In

addition, DOS also provides a miror command to record the

current disk information for formatting or deletion after

recovery, and this method is also effective.

2, zero track damage data recovery

The main boot record area (MBR) of the hard disk is on the zero

track. MBR is located in the 0 track 0 cylinder 1 sector of the

hard disk, which stores the hard disk, the main boot program

and the hard disk partition table. In a total of 512 bytes of

hard disk master boot record sector, 446 bytes belong to the

hard disk master boot program, and 64 bytes belong to the hard

disk partition table (DPT), and two bytes (55 AA) belong to the

end of the partition flag. Once the zero tracks are damaged,

the master boot program and partition table information of the

disk will be severely damaged, resulting in the hard disk being

unable to boot. Track 0 bad judgment: the system self-test can

pass, but the boot partition C disc lost or directory is missing,

there are laws of the hard disk " Creak "seek the

sound operation of the SCANDISK scan drive, a red" B "appears

in the first cluster, or can not find Fdisk hard disk, DM died

on the 0 track, this is the zero track damage!

Zero track damage belongs to one of the hard disk, but it is

a very important position, and once destroyed, it will have

serious consequences. If the 0 track damage, according to the

general method of the present data can not be a complete

recovery, usually 0 track hard disk through PCTOOLS DE disk

editor (or DiskMan) to make a sector 0 track deflection, the

use of track 1 as for the use of track 0. The data can be restored

through the cluster in Easyrecovery, but the data cannot be

guaranteed full recovery.

3, the data recovery when the partition table is damaged

Hard disk master boot record (MBR) sector where the virus is

also the focus of attack, by destroying the main boot sector

of the DPT (partition table), it can easily damage the hard disk

partition information, to undermine the purpose of information.

The damage to the partition table is that the partition data

is corrupted and the record is corrupted. So we can use software

to fix it.

Normally, after a hard disk partition, a partition table is

backed up to the floppy disk, the optical disk, or the removable

storage disk. In this regard, the domestic well-known

anti-virus software KV3000 series and rising has provided a

complete solution. However, for hard disks that do not have a

backup partition table,

Although KV3000 also provides the corresponding repair methods,

but the success rate is much lower. On the recovery partition,

Norton Disk Doctor NDD is absolutely powerful tool, can

automatically repair the partition loss, etc., can save the

data in the bad area of the floppy disk, forced to read and move

to other blank sectors. In the case of a hard disk crash or

exception, it could bring a glimmer of hope to the user. After

the problem occurs, start with the boot disk, run NDD, and

select Diagnose for diagnostics. NDD will scan the hard disk

thoroughly. If it is wrong, it will prompt you, then select the

repair project according to the prompt of the software, and

these problems can be solved easily.

In addition, the very familiar Chinese disk tool, DiskMan, has

a very practical function in rebuilding partition tables, which

is most appropriate for repairing the damage of partitioned

tables. If the hard disk partition table has been adjusted

partition software (or virus) severely damaged, will cause

serious consequences of the hard disk and the system paralysis,

and DiskMan records to re create the partition table

information through the unspoiled boot. As long as you select

the "rebuild table" in the toolbar of the menu, DiskMan begins

to search and rebuild partitions. In use, DiskMan will first

search the hidden sector of the 0 cylinder 0 head starting from

the 2 sector, looking for the partition table that has been

moved by the virus. Next, the first sector of each head is

searched. The whole search process is done in two ways:

automatic or interactive. The automatic way preserves each

partition found, and applies to most cases. Interactively, each

partition of the discovery is prompted by the user's choice of

whether to retain it. When the partition table, which is

automatically rebuilt, can be searched interactively once an

incorrect fault occurs.

However, rebuilding the partition table function does not

guarantee that one hundred percent of the hard disk partition

tables can be repaired. So remember, "ask no one for yourself,"

or "protect your hard drive."! Try to avoid hardware damage and

viruses, must do the backup partition table; if you do not do

backup, please download a DISKGEN software, and then in the tool

options, choose the backup partition table, is usually the

default backup to floppy above, if you do not have a floppy drive,

it is necessary to change the path. The output to the hard disk

directory. Then you should burn this backup file to the CD or

copy it to the U disk. Never put it on your hard disk. Oh, that's

the same as the backup effect!

4, after the deletion of data recovery

In the process of using computer in our most common data

recovery is after data recovery, but at this time we must

remember, do not partition or disk to write the information,

because of the possibility of a newly deleted file is the

maximum recovery. In fact, after deleting the hard disk

partition with fdisk, the surface phenomenon is that the data

in the hard disk has completely disappeared, and the hard disk

will display an invalid drive when it is not formatted. If you

understand how fdisk works, you'll know that fdisk just

rewrites the contents of the main boot sector (0, 0, 1 sectors)

of the hard disk. Specifically, the hard disk partition table

information is deleted, while no data in any partition of the

hard disk is changed. Since the deletion and formatting

operations are virtually unchanged for the data part of the file,

this provides the possibility of file recovery. As long as we

use some anti - removal software, which works by comparing the

partition table to restore the file, users can easily achieve

the goal of file recovery. At the same time mistakenly formatted

accidentally deleted the same recovery method there is no big

difference basically in use, as long as there is no hard disk

partition upset with the Fdisk command (using the FDISK command

to 40G within the hard disk partition, or it is convenient and

practical, are all on a BootDisk board support is no problem),

to restore the file is not cluster file, so most of the data

is formatted before can be restored.

And if your Windows system can also be used normally, so the

easiest way is to restore the Windows version of EasyRecovery

software, its hard disk data recovery function is very powerful,

not only to restore the files removed from the recycle bin, but

also restore the file FAT16, FAT32 or NTFS partition is

formatted.

The method of using the software is very simple, after

decompression, installation, run EasyRecovery, appear the main

interface. 4 function of the left button and the 2 button

software support, the disk can help us diagnose potential

hardware failure test, monitor and report on potential drive

failure, the use of drive space to view detailed information,

IDE hard drive jumper settings, and diagnostic analysis of disk

file structure and create bootable. Also, the data recovery

options provided by the 6 function buttons are critical to the

recovery of the hard disk data we need, and the EasyRecovery

Professional provides a wide variety of data recovery options.

These include: the use of advanced options to customize data

recovery function, find and recover deleted files, file

recovery, formatted from a volume not since the structural

information of any file system recovery software can recover

data to preserve the progress and create an emergency boot

floppy bootable.

In practice, we will select advanced options to customize data

recovery data recovery operations, after scanning the system

will display information on disk drives, where the information

we have chosen to restore the hard disk partition C disc, follow

the prompts, click "next" after the software EasyRecovery

Professional will automatically scan the partition, after all

the details the file information is displayed, including the

current and the file has been deleted. Followed to select the

file you want to restore, click "next" to select the target

location to enter the screen, after the moment of success

EasyRecovery to retrieve the missing files, then choose

"Cancel" to exit the tool.
