Accidentally deleted a partition of a dynamic disk , It's full of important data , So we started a crazy data recovery operation , Finally, all important data will be recovered , And can be opened normally , I hope this experience can help other friends who have the same experience .
<> Delete partition by mistake
System is win7 of , There is one 2T Hard disk （ Let's call it hard disk for the time being X）, After many partition operations, it becomes a dynamic disk , There are 3-4 Partitions , Each partition is not continuous （ This is what dynamic disks do , A partition may not occupy contiguous disk space ）.
stay “ Disk management ” Accidentally right click in - remove volume , The entire partition is gone （ Let's call it partition F）.
<> What should I do now
Deleting a volume simply deletes the partition table , But all the data is still there , So don't panic , Follow the steps below , All the data can be found .
* Do not on the hard drive X Write data in
from now on , Do not do anything that may go to the hard disk X Operation of writing data in , Otherwise, write a new to the hard disk X Your data may overwrite your original data , It's hard to recover .
* Save open file
If there is an open partition at this time F File , congratulations , Save these files to a hard disk , Then turn it off .
* Prepare one PE disc
PE There must be diskgenius.
only diskgenius Only most directory structures and files can be recovered , There will be some files that cannot be retrieved , Even if it is retrieved, it cannot be opened . This is the time winhex To remedy , I'll talk about it later winhex.
PE The disc can be used by itself ,U Pan do , If so PE disc , next step .
* Enough space on other hard drives
This is important , The files recovered by various tools should be saved in another hard disk first , Otherwise you restore the files and put the hard disk X After covering , Some files are found to be unusable , It may be too late to recover .
* Shut down
Turn it off , Ready to use PE Disk recovery data
<> Recovery phase I ：DiskGenius
* PE Disk start
* get into DiskGenius
* Select hard disk F, choice “ Search partition ” or “ Search for missing partitions ”, choice “ Entire disk ”, Start waiting .
* Copy recovered directory structure and files
This step is important !
Never save the partition table ! It says that this is a dynamic disk , Many files are in discrete disk areas , Therefore, the partition table recovered at this time is incomplete .
What to do now is , Check the recovered partition directory , Copy all the files to be recovered to other hard disks .
By this point, you have finished 50% Yes .
* Restore file
Incomplete files recovered in the previous step , So I'll do it again “ Recovery of deleted or formatted files ”, wait for , Or save the recovered files to the appropriate location bit by bit .
Come here 80% All files have been recovered successfully , But you will find that some files cannot be opened , At this time, because the dynamic disk is discontinuous on the disk when partitioning , The file location of partition table guidance is incorrect .
Look at the folders carefully , You will find that important files cannot be opened , Remember the types of these files , Then you need winhex Here to help .
<> Recovery phase II ：Winhex
You can turn it on at this time , download winhex Then use , Note that the same should not be done on the hard disk F Save file on . of course ,PE It's on the plate winhex better , You can use it directly .
* tool - Open disk - Select hard disk F
* tool - Disk tools - Restore by file type
Select the file type you want to restore , Start recovering , Remember to put the recovered files on another hard disk .
* Retrieve file
After you get the recovered files, you will understand why you didn't use them at first winhex The file has been restored ：winhex All recovered files do not have a file name , All numbers .
I already know what I'm looking for I've lost my file , Then be patient and look in this pile of documents , I'm sure I can get the important documents back .
<> summary
It's nothing to look for this wrong deletion of the partition , Of course, there are objective reasons ： Dynamic partitions are not contiguous in the diagram of disk manager , It's easy to select a small partition and delete it , It turned out to be part of a large partition , Finally, the whole partition was gone , tragedy .
* Why not diskgenius Software version
Free software version diskgenius Many functions don't work , And very slow .PE Although the version is low , But that's enough , and PE Many versions are professional , Full function , The most important thing is fast , It will not cause new write operations on the hard disk , security .
* Calm down
Don't calm down after deleting by mistake , Avoid any other operations . I click from “ remove volume ”, Successfully recovered in the end 95% File , Spent 2 Day time , Most of the time because I'm not sure what to do when I recover , And then back again . The above process is a successful experience .
* Slight regret
Of course, some files have not been recovered , Like some py The tools are gone （ because winhex There are no options of this type in ）. I think it can be recovered ,winhex You can study it again . besides ,word,excel,ppt Files can be recovered , It can be used safely .
