Remove Drive - RemoveDrive is a tiny piece of software that provides you with an efficient and quick method of safely ejecting removable drives from your system.
It allows you to use wildcards instead of the standard letters
The setup is straightforward and entails decompressing the archive in any desired location on your computer. While it does include an executable file, its role is mostly informative and you can learn more about the functions the app can perform. You can access the utility via the command line console, an option that some users can find slightly intimidating.
It is worth noting that the app is not dependent on the letters that are commonly attributed by Windows. As a matter of fact, you might as well use the device's ID string in your command to achieve the same result. Moreover, you can use wildcards, such as Flash, for instance, to eject the first drive with the keyword in the name.
It can help you detect the cause of the removal fail
You should know that you can even launch the program from the volume that you are attempting to remove by using the as drive command. Generally speaking, when trying to eject a drive in this manner, you are likely to get an error because the running EXE creates a temporary file that is running with the same parameters.
In the eventuality that the removal still fails, then the most probable cause is that an application or process is still accessing the drive. By employing the -h or -a parameters, you can find out more about the open handles on the drives along with the processes that prevent it from shutting down.
