What are the mobile hard disk failures?

Handling of bad sectors.

Repair or hide bad sectors of the hard drive after they are found to prevent them from spreading.

Method 1: Scan the disk marks bad sectors so that the system no longer deposits data to them.

Select the drive letter in Windows, select "Properties" from the context menu, and perform a full scan of the hard disk surface in the "Tools" option, and automatically correct possible bad clusters.

If not, you can try to boot the machine with the Windows 98 boot disk, and then run the DOS version of "Scandisk".

Method 2: Reformat.

Hard drive partitions with bad sectors will try to repair them during reformatting, and sometimes they can be repaired successfully. However, this method is not very effective, so it is often used in conjunction with the next method.

Method 3: Hide the bad sectors.

If you can't fix it, just hide the bad sector! The basic idea is to find out the approximate range of bad sectors. If formatted with format, record the percentage of bad sectors encountered, and calculate the approximate location of bad sectors according to the partition capacity; Or use the "disk scanner" to scan the hard disk to determine the approximate location of the bad sectors.

Divide this part of the space into separate partitions with the "partition magician" and hide it.

Tips: If the scope of bad sectors is smaller than the actual one, some bad sectors will continue to be used and spread; If it's too much, it's a waste of hard disk space. Before blocking bad sectors, back up important data first. +

I suggest you get a master to help!

Forcibly format the partition and then don't make any changes, remembering that there must be no write modifications.

Then go to the next Easy Me Data Recovery plugged in the portable hard drive and select Format to recover data.

I have experienced this with a 98% recovery success rate

Well, you have this problem, you don't want to see if it is a power supply problem of your mobile hard drive, it is recommended to hook up an external power supply first.

If not, it may be that the partition table is corrupted due to the important material on your hard drive, it is recommended to go to a professional data rescue company to do it.

Now data is money.

There is no need to test, it may be that the hard disk has bad sectors. I have encountered many situations in this situation, and the most direct way is to take the warranty to the top merchant.

A large amount of important data is stored in a portable hard drive, and if something goes wrong, it can make people anxious. So what are the failures of portable hard drives?

1. During the file copying process, there are frequent slow reads, IO errors, and a blue screen of death.

2. Partition Table Corruption: The partition cannot be opened, the hard disk is not formatted, and the file directory is corrupted.

3. The mobile hard disk accidentally falls to the ground or is violently impacted, resulting in the hard disk not recognizing the disk.

4. The hard disk cannot be recognized, the hard disk does not recognize the disk, and the hard disk makes a clicking noise when it is powered on.

5. The hard disk circuit board is burned out, and the USB flash drive is unplugged and unplugged abnormally, resulting in the USB flash drive being unrecognized.

6. The hard disk fails to recover data in other data recovery companies.

7. There is an error in the hard disk firmware, such as the Seagate hard disk firmware problem.

8. Ghost installation system error leads to data loss from the partition being merged on the hard disk.

9. The database is deleted or formatted to recover the bad sectors of the hard disk or the database cannot be loaded.
