How do you programmatically eject an USB mass storage device?

Question

How do you programmatically eject(safely remove) an USB mass storage device in Windows (XP)?

Answer 1

You could spawn a process and use a command line tool. This would also work from other languages such as java where calling the Win32 api is harder.

Answer 2

Here is a project (with source code) that appears to have figured it out.

Answer 3

There is an article about it at CodeProject: http://www.codeproject.com/KB/system/usbeject.aspx

Seems to do the trick.

Answer 4

In autoit, you have a script which does just that.

It basically comes from this Microsoft article and uses kernel32.dll DeviceIoControl function

Of course, this question appears to be a duplicate of Safe remove USB-Drive using Win32 API?, which gives other solutions

Answer 5

codeproject sample is just a poor copy of MS sample...
