FinalData saves valuable data from the USB flash drive

After a week of hard work, I finally completed the market research report. I happily opened the computer of the Organization and inserted the beloved mobile memory-USB flash drive. I just printed it out to make the transfer. However, I found N times in the USB flash drive, and did not find the folder where the file is located, and the original directory in the USB flash drive is full, it seems a lot less! What's going on? It seems like a Big Bang is coming. You know, it took a week to write this survey report, and it was just a hard time to finish it, what's more, there are still a lot of data, software, and other treasures in the lost directories. How can they disappear without a trace at once?

It won't be deleted! Check the properties of the USB flash drive. the space used is "53 M *" and the available space is "9 M *", which is the same as the property seen yesterday, I also selected all the displayed directories and files, and checked the properties. The result was "6 M *", so "47 M *" ran there? I suddenly remembered that when I shut down the USB flash drive last night, I unplugged the USB flash drive before it was closed. This may be because I inserted the drive incorrectly, leading to data loss in the USB flash drive. Sorry! USB flash drive, USB flash drive! I will treat you well next time. You can return the data to me!

The USB flash drive has no response! It seems that it is not clever, or ask the teacher online. Haha! In fact, my online teacher is a search engine, which is a good teacher. If you ask a keyword, it will show you many and many answers. I often ask the instructor-"Baidu" search, and enter the keyword "data lost in the USB flash drive". Then I can see that the instructor has listed many online introductions about this, in one of the links, we mentioned that if data on the USB flash drive is lost, we can try to use the "FinalData" software. This is a software that can read data by sector and restore data as much as possible. I seem to have seen a glimmer of light in the dark. After some effort, I finally found this software.

In an uneasy mood, open the compressed file and double-click "setup.exe" to start installing FinalData 2.0. During the installation process, the software will prompt you not to install FinalData on the drive containing the data to be restored, otherwise, the data may be permanently overwritten and cannot be restored. The default value is 1, which is installed on the "C:/" drive. If you do not want to install it on "C:/", click "previous". In the "select target location" window, click "Browse" to select another folder. Because the drive letter of the USB flash drive is H, there is no problem of Overwriting data, you can install FinalData on the C drive. Then, follow the prompts to install the program step by step.

There will be a 2-style "FinalData" icon on the desktop.

Double-click to start the "FinalData" program, Interface 3, Simplified Chinese version, which is very suitable for users who cannot access E. Although it is the first time to use, it is easier to get started.

After reading the menu item by item, the "open" under the "file" should be to open the disk for data recovery. After clicking it, a "select drive" window appears, 4.

Select the "Removable disk (H :)" disk and click "OK". A "Scan root directory" window is displayed, 5. This is the normal and deleted directory and file of the program in the flash drive. If only FAT1 and FAT2 are damaged, FinalData can scan directories to list data in the "deleted directories" or "deleted files" list in the program.

However, if the root directory is damaged, you must scan the cluster to restore the data. Therefore, after scanning the root directory, the program automatically enters the "Select Sector range" window, perform cluster scanning, 6.

Select "Full scan" and follow its default value to scan from the start position of the partition to the end position of the partition. The time required for cluster scanning varies depending on the CPU clock frequency and memory size in the system. 7. The status of the current scanned USB flash drive cluster is displayed.

In fact, when a file is deleted, only the first character of the file or directory name will be deleted. FinalData searches for the deleted file by scanning the sub-directory entry or data area. After a long wait of 20 minutes, the FinalData program found the lost directories and files and listed them in the "Lost directories" and "lost files" items, 8.
Document. body. clientWidth * 0.93-146) {this. width = document. body. clientWidth * 0.93-146; this. style. cursor = hand; this. alt = the image has been reduced. Click to zoom in to display the original image.} "border = 0>

The directory information usually includes detailed information about the file and directory, such as the file name, creation date, and file size. If the directory information is damaged, the data cannot be used. The file size discovered after the cluster scan is set to the default size. FinalData uses the # code plus the cluster number of the file as the name of the file. Open the directories one by one, and finally find the lost files, 9. It is really hard to express the feeling of seeing friends who have been in violation for a long time.

How can we restore these lost directories and files? Select "Lost directories", click "select all" in the "edit" menu, and the directory on the right of "Lost directories" is selected, 10.

Click "Restore" under the "file" menu, and the "Select Directory save" window pops up. Select a file directory in the hard disk outside the USB flash drive and click "save, 11.

The following shows that the progress bar of 12 is constantly flashing, and all the lost directories and files are continuously returning to the hard disk.
