The reason is simple: some files on the mobile hard disk are still in use.
But some of these used files are explicit,
Some are implicit (that is, you can't see any files in use).
For clear:
1.daemon tool loads CD image files (ISO, mds, etc. ) on the mobile hard disk.
No unloading
2.IE opened the html file on the mobile hard disk.
3. Run the exe file on the mobile hard disk, and don't close the mobile hard disk.
Of course, there are other clear ones that cannot be listed one by one. I believe I can find them.
If all explicit references to mobile hard disk files are turned off,
There is also a "can't stop now" and can't pull out the mobile hard disk.
There are generally two ways to solve it:
1. Close (logout method is still useless in most cases)
This is the stupidest way,
Before I thought of a new method, I had to adopt this method for the data security of the mobile hard disk.
2. Run the window optimization master's tool "memory arrangement" and you can safely delete the mobile hard disk.
I found this method by accident.
According to this method, I infer that the implicit reference estimation of mobile hard disk files is to establish a cache or shortcut to access mobile hard disk files in memory.
After completing a task, it is not cleared, which makes the system think that these files are still in use. Memory cleanup released these erroneous references.
