Oh nice Stan. I didn't know about this free one. As I use either:

Safely Remove Hardware better alternative
http://www.safelyremove.com/

Zentimo is an external storage manager
http://zentimo.com/

Both are from the same company and Zentimo has more features. But I
don't really use the extra features so I don't care which one I am
really using.

Maybe find a tool on Uwe's site ?

You quoted the reason: "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."

I do the same thing as Gene, and I have the unmount command as part
of the batch file.

You mean you do that on some Linux/Unix host since those have the mount
and u[n]mount commands. For Windows, it is mountvol.exe for both
mounting and unmounting (as Dan already mentioned). Or maybe you
installed Cygwin on your installation of Windows to get those *NIX
commands.

I am not sure how Stan is going to answer. But the following will do the
job too.

USB Disk Ejector (free)
http://quick.mixnmojo.com/software/usb-disk-ejector

USB Safely Remove (not free, except trial) - I use this one
http://www.safelyremove.com/

Zentimo (not free, except trial) - I use this one too
http://zentimo.com/

As far as i know Windows does not use a cache for usb devices unlike *nix.
With *nix you do need really to unmount a usb device since the cache may
not be written completely.
Windows, from what i was reading, does not have the same kind of approach.
Doesn't a simple unmount do the job (if needed)?

WARNING: Do NOT do this! You probably do not want the result.

This will unmount the volume, but not the USB device. It deletes
the mount point. The USB drive will be recognised when mounted, and
Safely Remove Hardware will work for it, but there will be no drive
letter. Note that this drive letter deletion persists across a
reboot.

>http://ss64.com/nt/mountvol.html

The above is what I should have read first. Using it, I was able
to recover.

A bare
mountvol
will give a list of volume names of the form
\\?\Volume{<GUID value>}\
The one you just mucked up will have a statement that there are no
mount points. To patch it up, enter
mount <drive>:\ <volume name>
where <drive> is a drive letter -- I assume an unused one -- and
<volume name> is the volume name mucked up. You should then be able
to use the USB volume as a drive again. This change will persist.

This worked. It is a GUI program that also works on the command
line. Any output is GUI.

Gene Wirchenko

DO NOT DO THIS WITHOUT READING UP.

This unmounts the drive letter by deleting the mount point. It
will not unmount the USB device. The deletion persists across
rebooting. See my other post on how to recover.

Gene Wirchenko

I think Stan's http://quick.mixnmojo.com/software/usb-disk-ejector looks
like it will do the job too. I was really just pointing out to Roger
that Gene had asked (and Roger had quoted!) for a way that would work in
a batch file, and Roger had suggested using an icon. (I wish I'd kept
quiet now!)
