Formatting is required for "Data loop redundancy error" in a partition of a mobile hard disk

A 200 GB mobile hard drive purchased four years ago has two partitions: GB and GB. A folder was inaccessible a long time ago, and the disk was formatted every time you double-click it. A few days ago, the drive letter was unavailable because the disk failed to exit and the data line was forced to be unplugged. I tried several processing methods in one day and recorded them here.

1. Use the disk to check and repair

Method: Right-click a disk and choose Properties> Tools> check errors to start checking.

Result: failed.

Although the disk can be found, right-click the disk and it will crash. The right-click menu cannot be displayed.

2. Use tools to restore partitions

Search Baidu for "mobile hard disk partition formatting error". The reason is that the partition is broken and you need to repair the partition.

Step 1: Back up data

Using R-studio to back up data is very powerful and fast. There are many versions, which are the cracked green version. This is not the case. I used 5.3, 6.1, and 5.4 versions to register the last one.

Step 2: restore partitions

This step is tortuous .....

First, HDTunePro5.0 is used, which is scanned by disk instead of partition. One of them is "error scan", but the scan result is normal.

Then, the "easy my Partition Table doctor V3.1" function is used, which has the "repair guide partition" function. After clicking it, the prompt is normal, but the problem still cannot be solved. Later, manually edit the attribute because the demo version cannot be saved, and the operation is interrupted.

Then, we used WinHEX, the most awesome tool. This is also a lot of versions, the last use of WinHex V16.3 SR-2.: http://bbs.360.cn/4004079/253407624.html

The offset 000 to 1F0 of each partition is the stored boot information, and the backup of the boot information is stored in the last sector of each partition. Therefore, backup is used to overwrite the Boot Sector. At first, I felt that this action was dangerous,

I cannot use another good partition on the mobile hard disk, but I have backed up important data in advance, so I am bold enough. However, the result is still disappointing. You still cannot open this partition.

Finally, I think of some web pages that use the chkdsk command to check and repair disks. As a result, the system becomes useless. Enter [run as/user: zbl "chkdsk I:/F"] in the command line and press Enter. Enter the zbl password. A disk check window is displayed. After about ten minutes, check and refresh the folder on my computer, and the folder that was originally broken is also good.

It took a day and finally solved it in the simplest and most direct way.

Cause Analysis: two errors are displayed: "inaccessible, parameter error". Format them. The other error is "data error (cyclic redundancy check )", when the problem was solved, the system stared at the first format and encountered a partition error. Therefore, it took a day to solve the partition error. If you use "data errors (cyclic redundancy check)" to find a solution, the answer is to use chkdsk to check the disk. If you want to analyze the problem in the future, you must think about it in a different way.
