Hello
I'm getting the "Problem Ejecting USB Mass Storage Device" message when trying to eject my WD My Passport Ultra.
I'm trying to remove it the proper way but I can't.
I end up having to shut down the desk top to remove the device.
Just used the device for the first time today and there were no installation issues.
OS is Windows 7.

When I first connect the device and don't open any of the files, there is no issue ejecting the device the proper way.
All that I have on it are pictures.
It's only after I open a folder that this issue happens.
I close any images I've looked at before trying to eject the device.

I know this is a common problem and the issue seems to be that a program is still accessing the device but, I can't seem to find any program on the computer that is accessing the device.
I don't have anything open when trying to eject the device.
The only thing that is running that I'm aware of is Microsoft Security Essentials and Malwarebytes.

I've opened task manager and under processes it's showing 00 for CPU, and under performance the CPU usage is 0%
However, it does show the Physical memory at 14%.

Am I checking the right way to see if something is accessing the device?

Is this a new problem or new hardware or has the issue existed for some time?

You might find some resolution in the procedure at https://answers.micros​oft.com …54-e011-8dfc-68b599b31bf5 (external link). The steps outlined and the suggested utility will help you find the program or window that might be using the device. Sometimes shutting the program or service down and rebooting will clear the issue.

I have multiple USB mass storage devices and I get the same" Problem Ejecting USB Mass Storage Device" message for some, not all.
It's all pictures on all of the devices so I would think there would be only one program used to access the pictures.
I'm not a computer expert so, I'm not completely sure about that though.

This is not a new issue to me but, I was surprised to see it happen with this newly installed device.

I thought that maybe Photoshop CC or Lightroom CC might be trying to access the device but I have both programs closed when not being used.

I'll check out the link you provided.

Thanks

There is probably something running that is causing the error. --Control ALT Delete-- and look at the task manager and the processes that are running.
Find the process that is causing the drama and kill it. Should solve the problem,

Run "Resource Monitor" which is built into windows. Look at the tab for "Disk" and it will list all of the processes with Disk Activity.

Task manager shows that there are 97 processes.
The only thing showing under the CPU heading that has a number in it is, "System Idle" and that is showing 99.
The remaining processes are showing 00 under the CPU heading.
Is that not an indication that no other processes are running?
I tried to end the "system idle" but it wouldn't let me.

This is the "Disk" information in Resource Monitor.
From that information showing, how am I to tell what program is using the device that is preventing it from being ejected?
"J" is the letter representing the mass storage device for which I get the "Problem Ejecting Mass Storage Device" message.

When you took that screenshot of the Resource Monitor, did you try and duplicate the issue first? If not, open Resource Monitor and then insert the external drive, then open and close an image on the drive and then try and eject the drive. Also, expand the "Disk Activity" column, currently you have it closed. It will further break down the "system process" and give more information there.

The "system" process could be any of a number of things. There are ways to break that down further (external link) but before doing that I would first confirm that the Windows indexing service is turned off for that drive and also exclude that drive from your antivirus programs and then try and eject the disk. Alternatively, try killing all of the Microsoft Security Essential and Malwarebytes processes before ejecting the drive.

When that Resource Monitor screenshot was taken, the external drive was connected.
An image was opened and closed and then the attempt to disconnect the drive was made.
I repeated this process a couple of times but ended up with the same result.

So, after getting tired of trying to get the external drive to disconnect properly, I simply unplugged it from the computer.
I know external devices aren't supposed to be removed that way but, since doing that, I can now properly disconnect the same drive with no "Problem Ejecting USB Mass Storage Device" message.
I've connected the drive a few times since, opened and closed images, and disconnected the drive using the below method and haven't had any issues.
Go figure.
Thank you for your replies.

Should this happen again, there is a utility out there that will identify what is using your mass storage device and optionally shut it down for you. See http://safelyremove.co​m/index.htm (external link).

Note the utility is not free except for 30-days but that may be all you need to identify the culprit.

You could also use the Microsoft Process Explorer utility I mentioned in reply 2. It is discussed in "Method 1" of the provided link or go to https://docs.microsoft​.com …ownloads/proces​s-explorer (external link).

I did try the original link you provided and I must not be doing something right as what appears on my screen is not the same as what should be appearing.
It appears that WinRAR is needed to open the downloaded Process Explorer Zip and I don't have that tool.
An evaluation copy comes with the download but it seems like it might not have the full functionality of the purchased version of WinRAR?
Either that or I haven't opened the Zip file properly.

This is part of the instruction on how to use the utility:
Method 1:
a) Download Process Explorer from the link below
http://technet.microso​ft.com/en-us/sysinternals/bb8966​53 (external link)
b) Click Find, Find Handle or DLL (Dynamic Link Library) in the tool menu.
c) Type the drive letter of the USB device in the Handle or DLL substring textbox, and press Search Button.

When I click on the tool menu, none of those 3 options listed in step b appear for me.
The closest option that shows is "find files".
There isn't a search function either.

What shows below on the left side of the screenshot is how things should look after the Zip file is opened and what shows on the right is how things look on my screen after downloading the
Process Explorer Zip file.
Again, I'm sure I'm not doing something right.
I'll bookmark the second link you provided for possible future use.
