Have you ever encountered this situation?
Plug in the USB flash drive/hard disk and open my computer file explorer
It will be stuck for half a day and you can't brush the disk symbol
As soon as I unplug the USB flash drive, open my computer's file explorer, and the drive letter can be displayed normally
Or maybe it's very slow to copy certain files
In the end, it is often the copy that fails
Some people think that it may be a virus in the USB flash drive
This scenario is not impossible
If it is a medium computer virus, you can try to use antivirus software to kill it first
Or try copying files in a PE system environment
If you still can't copy the file properly
All kinds of signs are indicated
Your USB flash drive is likely to have bad sectors
What does bad sector mean?
You've all seen CDs, right?
The disc data is stored on the coatings on the surface of the disc
If you accidentally scratch the surface of the disc
Those scratches are bad tracks
If the computer defaults to your USB flash drive, it is intact
When it reads bad sectors, it can't get data
I kept trying to read the bad sector data again
So the computer keeps getting stuck in the bad lane
That's what we're trying to do is find out what these bad sectors are
Then block it out
Let the computer not read these bad sectors to complete the bad sector repair of the USB flash drive
Note that loop repair is not repair data
It's not that the broken place can be repaired and reused
It's about making the bad places no longer use
Because the storage of the hard disk is divided into many small compartments
The data is stored in small compartments
Let the computer not know the existence of that bad grid to realize the repair of the hard disk
There are many hard drive repair tools
I'll take DiskGenius as an example
Let's explain how to repair disk bad sectors
Select Bad Sector Detection & Repair under the Hard Disk menu
Check whether there are bad sectors first, of course, you can also directly try to fix them, and if you detect bad sectors, you can directly help you fix them
Save yourself time and re-scanning
The repair time usually varies depending on the size of the hard drive
The larger the hard drive, the longer it will take
Typically, a 1TB hard drive takes 1 hour
You can interrupt the repair operation at any time
The software saves the progress of the repair
Next time, open the software and select the last detected record
Once the software has detected it, it will know the health of your hard drive
Generally, there are more excellent and good data blocks for newly bought hard drives
If it is normal, there are too many data blocks
It shows that this hard drive has a short lifespan
Damage is the block of bad tracks, if it is not good, serious, and there are more damaged blocks, you should pay attention
Don't store important data on your hard drive
Because this hard disk is basically about to be scrapped
The repair of bad sectors in hard disks is to shield these bad storage blocks
After repairing, re-test the hard drive
The number of poor, severe, and damaged blocks should all be 0
