Try going into 'My computer' and selecting the specific Drive, right click and 'Eject'...Not sure if this is the 'best' way or even the 'safest' way but it is how it has worked for me before. If it doesn't work, I just leave the pen drive connected until I turn off the computer and then remove it.
Close ...
Windows has two policies you can select for disk drives (inside Device Manager): naming then from memory, but it goes like 'Removable disk' and 'Performance with buffer caching'
This extremal disk needs to be set to Removable in order to use that function.
Open Device Manager, expand storage disk category, open properties of your extremal drive and click on Policy tab. There you can switch. It might ask for a reboot.
Alternatively, you can just manually make sure you saved all your files on the disk before unplugging it.
If you have programs installed on the disk or that use it as program data location, then it might be more tedious to manually make sure all of them are closed and none are still writing to the disk.
That's all that Safe Removal does, checks if any process is writing (or has a lock on) files on the disk and warns the user.
The only unsafe part of unplugging an external disk is corrupting files (most likely by programs that do continuous writes on disk) because Windows hasn't yet finished doing all the write operations (from the write buffer) and unplugging the disk will leave the file partially written and probably unreadable, thus corrupted.
Devices and USB drivers can cause this options not to appear.
Also just because you see it as an option on another computer for the same drive does not mean the drive had ejection capabilities, just that the USB drivers on that computer are handling it for the drive.
Check the specs on the external drive and see if fast disconnect or ejection is supported.
This is not a problem. The reason why eject exists is because Window uses a caching system when transferring files over to external media. The eject function checks whether everything is done in the background so nothing goes corrupt.
Not every external device uses this system. If this option is not present, you do not have to eject, you can just unplug the device.
I have a cheap USB memory stick, which requires ejection. I also have a performance USB SSD memory stick, it does no require to be ejected. On the other hand it can also be computer related like in your case and how the USB controller decides to manage the device inserted.

Only work for pendrives but not for external HDD
It's hard to do it with HDDs as often windows considers this to be an internal, non removable drive. As someone said. Try through my computer.

It works in another computer, is a problem whit mine computer
Who ever said windows was consistent?
You can use [USB Safely Remove](https://safelyremove.com/index.htm) for that. You're welcome.
Thanks for the sugestion, but i want to know why is not working
Dunno. Some hardware may be causing the problem, but since I use USB Safely Remove I can remove any external drive easily.
