The lost hard disk that was modified by a rescue Error

Recover the lost hard drive modified by mistake-general Linux technology-Linux technology and application information. The following is a detailed description. I installed ubuntu on my friend the day before yesterday and had an episode.

All the friends who have used it know that the partition format of Linux is completely different from that of Windows. There are no FAT32, NTFS, and other formats, but EXT3 formats. The two are completely incompatible.

When I start and install ubuntu with a CD, I have an option. ubuntu will use the hard disk partition. During the original installation, the hard disk space in the airspace is reserved for ubuntu. In Windows, the hard disk space is dumped first. This time, however, it was coincidences.

After the CD starts the machine, Install it. When it comes to selecting this step, I did not take a closer look. I will go directly to the next step and the next step ...... As a result, the hard disk format was changed instantly! I have skipped the reminder that "format changes are irretrievable! The entire hard disk is used by default.

Interrupt now! Directly shut down after power failure, and then re-enter the ubuntu Live CD mode, then look at the hard disk, silly!

Previously, the hard disk had four partitions, all in the NTFS format. Now it is missing. The hard disk is divided into two partitions. Except for a m Linux Swap partition, all the other partitions become one EXT3 partition.

Continue to Install and check whether the data can be restored in the partition selection step.

What should I do? Take a look at the DOS as usual. Start the machine in DOS mode. Look at FDISK. It is not recognized at all! Other Norton tools are useless. Remove the disk and mount it to another machine. Go to Windows and check out the details. The entire hard disk contains unknown partitions!

The key is that there is a lot of important data in the hard disk!

Save the data first! Use Easy Recovery Pro to scan the hard disk immediately. files and data should be able to return!

As the scan continues, we can see that the number of retrieved files is increasing rapidly, and we feel a little bit of relief and gratitude in our hearts. But then I found the problem: because of the different formats, the original file name was not restored! Isn't it a mess of hundreds of thousands of files on the entire hard disk? Stop, stop, and try again.

Run DiskGenius.

Start DiskGenius. This process seems to be a little longer than in the past. At first glance, it is better than other software and recognizes the Linux primary partition and swap partition. I checked the partition information and thought that it would be nice to retrieve the original information completely, but now it is not a partition corruption, but a complete new partition. To manually adjust the original status, you must first know the details of the original partition, the size, the starting and ending positions, and then directly modify the partition information on the hard disk, however, no such information is available.

I am not very familiar with my friends, but I am very enthusiastic about pouring tea to me, but I am not aware of my inner panic-if this is the performance, it is too shameful, and the data is lost.

At this time, the operation should be very cautious, because I know how important it is to save the original state. If you write something blindly to the hard disk at this time, it will only lead to the hard disk being pushed into a truly irrecoverable situation. So although DiskGenius provides the "search for lost partitions" function, I have repeatedly checked whether this function can be used because my partitions are not damaged.

I know that partition scanning does not write anything like a hard disk, but I am very careful about it. I decided to try again. I chose to search. When you press the button, the screen immediately refresh and "find four partitions "!

I can find it! Looking at the report, my heart is so excited!

Save the retrieved Partition Table and restart the machine. Haha! All the original partitions are back! The file is undamaged!

All of this is done without the knowledge of a friend. That's really "why is it true !"

Continue to install ubuntu, accept the previous lessons, and the installation is successful.

On the way home, continue to think about the scene and give yourself a summary.

DiskGenius has unexpected features. The reason for saving the original partition is that DiskGenius scans the original information on the hard disk, while the Linux format is completely different from that of Windows, so the information of the new partition does not overwrite the old information, I did not write to the hard disk after an error, and kept the original hard disk information intact. Through this accident, I have learned everything with caution and learned another piece of knowledge unexpectedly, without causing any loss or loss to my friends, in general, it is still very rewarding.
