Hard raw format data recovery

The most important thing to do with SAP is materials and teaching materials. I had a problem with my mobile hard drive two days ago, so I had a poor idea about more than 100 GB of data.

The problem is: the format of one of the three shards is raw, and the size of the byte is-0kb.

I used finaldata. The speed is too slow, the directory is incomplete, and I gave up. I can use diskgeniust to find data. Unfortunately, most of the documents are damaged;

Use diskgenius and ptdd to repair partitioned tables. The repair fails;

Use easyrecovery to restore data. When executed to half, an error occurs when reading the partition. After canceling the operation, you can view the deleted data, the data in the hard disk root directory is missing (My ides installer and sap mm pa textbooks can all be on top );

It took a long time to use filescavenger to retrieve 80% of the Data. Unfortunately, the file name is too long to be recovered, and many unknow files are generated.

I once had GB of information in front of me, but I could not cherish it ...... (See postscript)

What can I do to save you? My sap information! I want to retrieve the remaining information.

1. raw format reason
2. raw format Solution

Experience:

1. raw format reason

I searched the internet for the reasons for the formation, and I will not tell them one by one, but the results will have a cause.
The correct statement found on the internet is caused by DBR damage to the hard disk. If I do not understand the hardware, I will reference the explanation provided by my predecessors.

2. raw format Solution

I can say that I have no experience in hard disk data recovery, so this time I just learned how to find a solution for myself, it is a great fortune in the mid-year cool. Since the hard drive in raw format is my GB Data disk, which stores around GB of data, I was shocked by the cold sweat when I saw it changed to raw format, several years of photos, N years of ISO collection, countless code written overnight; if the smoke disappears, I doubt whether I have the energy to write all the code again... Now, let's get down to the truth. Format directly without data recovery. No more ~ _~

Start of recovery:

I have no experience. Like me, it is a top priority to package the partition or the entire hard disk into a gho file on the data disk using ghost immediately. Then we can start the work on our own. If there is no backup, don't play with me, or your data won't be able to play. Pai_^

The following is a paradox found on the Internet:
1. Set raw partition permissions.
I don't understand where the partition is changed to a raw format of 0 bytes? TMD's nonsense is a waste of time, but it's also a mistake!

2. Group microconfiguration.
It's a matter of partitioning, but it's still the system. Isn't it a matter of shrimp?

3. The drive letter is changed and restored. Delete the original drive letter and re-allocate the drive letter.
I tried it once and gave up immediately. Seriously suspect, is there such a simple solution?

4. Use Win98 to read the raw score format.
In itself, my drive letter is converted from NTFS partition to raw format. is 98 supported? In the same serious suspicion, I am not really interested in installing a 98 for testing. If I cannot read the drive letter through the msdos7.1 test, I immediately gave up.

Some people think it is the right way to try:
1. Access the PE to read the raw disk. I heard someone has succeeded. But it seems that my disk does not work.

2. I used the 3.0 repair and Guidance Method of my Partition Table doctor to fix the problem. When I looked at the page, it seemed like a ptdd vest. I don't know what the relationship between the two. However, I tried both the table doctor and ptdd in the partition, but the error cannot be fixed when the boot is fixed. But I personally suggest you try it.

3. Go to DoS and load the DOS for NTFs software. If your drive letter in raw format is detected, congratulations. Then go to "death". I heard that it can be correctly identified.

4. Use chkdsk to fix the issue. But from chkdsk/r x: Try to chkdsk/f x: No, I don't know if it's my hard disk or my RP is worse or not. But you can try. After all, it is the simplest.

5. Use PQ to adjust the partition as needed. Do not save the partition after exiting. This method also shows that someone has succeeded. However, I still cannot try my hard drive, and the revolution is still unsuccessful. I continue to work hard.

6. Right-click the drive letter in raw format to bring up the formatting dialog box and press start formatting. Click Cancel immediately and restart again. You can see that someone has succeeded without worry. But do not hook up with "quick formatting". Otherwise, if your hands are not fast enough and you do not have a ghost raw partition or hard disk, your hopes for data recovery will be slim. Similarly, this method still fails.

7. Use the diskgen partition repair function of the DOS version to fix the problem. Similarly, I still see that the good luck guy on the Internet has succeeded. However, this method is immune to me. Depressed. After restoring four partitions, my data disk has never been used to dividing four partitions.

8. Partition merge method. Prepare another hard disk and divide it into two partitions. Generate a gho file from the raw partition, restore it to one partition of the other hard disk, and then merge the two partitions with PQ. I heard it is feasible, but I still cannot. NOTE: If it is an NTFS partition, NTFS is of different versions, that is, the NTFS partition of XP and the NTFS partition of 2003 are of different versions. Do not use raw format partitions, which are originally 2003 points. The new hard disk uses XP partitions and PQ for combination. This will make a mistake.

9. Use winhex for manual repair. We can see that some cool people have proposed it without worry. But I do not know whether it is successful. Although I don't understand it, I think even if the amount of work that is successfully restored is huge and the technical demand is high, I will give up and I can't afford it. However, I saw a moderator using C language to develop this kind of tool in the reply post. However, I had nothing to do with pm, so I had to do it myself.

10. If you have a good friend and unfortunately tried the nine methods above, your raw hard disk may have been around the same, recover the gho file backed up in raw format to another hard disk and start your difficult data recovery journey. This is your best choice. I tried the following data recovery software:

Finaldata
Finalrecovery
Easyrecovery
Easy data recovery wizard
Recover4all pro
Filerecoveryangel
Easyundelete
Recuva
Objectrescuepro

Finaldata recovery files can probably be recovered to some files, and many of them can be recovered only after they are deleted. If this software is used for recovery, if the data disk is large, remember to find a computer with a partition greater than or equal to a raw data disk to restore the data disk. Otherwise, scanning time will be wasted and it will be cleaned up. practice is the only criterion to test the truth, I will not waste my water.

Easy data recovery wizard, dedicated raw format options are available for recovery, but personal testing does not work.

Easyrecovery should be a well-known data recovery software. However, in my test, only part of the files can be restored. If the files contain Chinese characters, the file content will become garbled. The reason is that the "zizhu" brother of the free sky said that it was the reason why ghost was used, because my data disk gave me all the above methods, I don't have to consider testing.

FinalrecoveryWhen the king appeared, none of the above methods worked. It eventually restored more than 70% of my data, which is indeed a powerful tool to deal with raw format. However, if there are many original folders in raw format, it will be exhausting. This software cannot restore folders. It will list the previous folders one by one, and then manually select a file to restore the files. The file name will not change, and the content is also complete, I just scanned more than 7000 folders on my hard disk and almost watched the flowers. The disadvantage of the software is that every time a certain file is recovered, that is, every time 1000 or several hundred files are recovered, the software will go wrong. The original version and the Chinese version both have the same problem. I do not know whether it is the reason for the 2003 platform. I did not use the XP test.

Note: I once had one hundred GB of data in front of me, but I did not cherish it. I will not regret it until I lose it. If God gives me another chance, I will say four words "daily backup" to the one hundred GB Data. If you have to add a backup period for this data, I hope 10 thousand years. It is a bit exaggerated, but fact data is always fragile. Many things will be cherished only when they are waiting, just like feelings. This is the King's path.
