What should I do if, when connecting a USB flash drive or a removable hard disk, Windows asks to format the disk?
In this post I will try to answer this question, but first let's look at the reason, in order not to repeat the mistakes that lead to such problems.
And the reason in most cases lies in the non-observance of the elementary rules of safe work with removable media.
Causes of the problem
Often I see even quite competent users pulling flash drives and removable hard drives out of computers and laptops without use.
From competent users, I hear quite a reasonable explanation for this action - it means turning off "on hot" and this is true ... BUT !!! It is about the connector and its capabilities, and not about disconnecting storage devices !!!
Of course, you can turn off USB devices such as a printer, scanner, headphone, mouse, or keyboard without turning off the computer, but information storage devices have one very important feature and cannot be turned off like this.
The fact is that the removable hard disk or flash drive at the time of shutdown can access the operating system or some of the running programs. At the same time, it is not at all necessary that some files will be copied to or from the disk at the time of shutdown. Sudden shutdown of storage devices can damage files or file system.
If the file system becomes corrupted, the next time you connect the device to the computer, you will see a message that the disk is not formatted, that is, Windows asks you to format the disk:
Physical damage to the disk may also lead to such an error. That is, disk sectors that contain file system overhead can be damaged. But still, software file system corruption is much more common.
Solutions to the problem
As a rule, to solve such a problem is quite simple and for this you do not even need third-party programs. It will only be necessary to check the file system using standard Windows tools.
To do this, we refuse formatting, and then call the context menu on the icon of the problem disk and select "Properties".
