#What does it mean when the USB disk is write-protected?

Write protection means that it can be read but cannot be modified. But it is different from read-only. Read-only can be deleted, but write-protected cannot be deleted. On the one hand, write protection protects the original files and prevents misoperation; on the other hand, it prevents viruses from attacking the file data.

U disk write protection is equivalent to read-only, which means that the content can be modified but cannot be saved. It is specially designed for U disk anti-virus.

When write protection is turned on, the data in the disk will not be modified, effectively protecting disk data. It can also prevent viruses from infecting the disk.
