USB Drive Unmount Command

Hello:

Does anyone know of a command for unmounting a USB drive? I
frequently copy from system to system using batch files, and I would
like it if the drive could be unmounted at the end of the batch file.

Sincerely,

Gene Wirchenko

Wonder if this powershell approach would work?

or a shell.application COM method?

To the best of my knowledge there is no native way to do this, but
there are 3rd party tools that allow you to script unmounting/ejecting
a USB drive. I've not used it, but I've seen where deveject.exe is
purported to be able to do this.

Over all the years of using either a USB HDD or a USB Pen drive I have
never unmounted it before pulling the plug on either and have never had
any problems. This on XP and Vista and Windows 7.
Has anyone had a problem?

An actual problem? No.

An annoying message from Windows the next time I remounted it?
Usually. So I always eject, just to avoid the message. And in so
doing, I also avoid that off chance of an actual problem.

Why not just use the built-in "Safely Remove Hardware" icon?

I have a number of times. Although this was 5 years or more ago and I
don't recall what Windows OS it was. And the worst one had a scrambled
directory. Worse it would randomly popup new filenames with strange
characters. Reformatting fixed the problem. Thank goodness for backups,
as nothing was retrievable.
