Almost everyone who uses a computer has dealt with this problem of “This device is currently in
use. Close any programs or windows that might be using the device, and then try
again.” every now and then. This is the result that we get in the form
of a pop up window while trying to remove an external media, like a pen drive
or a hard disk, from the port of a computer by clicking the safely remove hardware button. But is this
actually a problem?
Most of us
simply plug out our devices without knowing the possible risk they are
unknowingly putting their data to and the potential threat that their media is
being subjected to. This behavior can be because of three possible reasons:
Reason 1: They do not know about safe
removal or quick removal and about its importance.
Reason 3: They have quick
removal enabled in their systems.
For both the
types it is better to know what this safe removal is and why is it so
important. Well only those who have dealt with the results of this issue know
how drastic they can be and they do not want to face them again. Just to make
it brief, if not taken seriously you can lose all your data stored in the media
permanently. Moreover your media (pen drive/ hard disk) might also get damaged
beyond repair. Let us try to understand this concept and know about the
possible solutions and the ways in which we can save our important data.
Every
storage media has a file
system that it uses to store,
retrieve and update data to and from the media. This file system is of grave
importance for the working of the media. This file system manages the access to
the content of the media, arranging storage space and updating the properties
of your media contents with the properties of the system under which the media
is being used (like when you select “do not show hidden files” then the
ones in your hard drive also stay hidden). You can intellectualize this file
system as a log that contains entries of data and associated operations on this
data.
When you are
using a media on a computer, its file system gets updated as you perform
operations on the media. These operations include adding data to the media,
deleting data from the media or updating data. Whatever the operation may be,
it gets logged in the file system of the media along with other details like
the location of the data.
During safe
removal, the operating system stops all such operations on the media so that it
can be removed without disturbing its file system. The job of safe removal is
to ensure that the drive is not being used by any program and that its file
system is not being updated by that program.
If the media
is removed while it is being used by some application, there is a fair chance
that the file system can get damaged. In that case, the data inside your media
also gets damaged. Since the only way to find data in the media is this file
system, it needs to be restored to a working state before it can be used again.
Generally
the operating system (windows in our case) detects this and can fix this
automatically. You might have seen the scan and fix prompt by the
operating system when you plug in your media. It is the way in which your
computer tells you that your media has a corrupted file system and you should
check it and fix it before use. Although it is optional and you can still use
your media without any fix. But at times the problem is not that simple.
Sometimes the file system gets corrupted so badly that it is beyond the
capabilities of your operating system to repair it. Then you are left with only
two options:
Format: A format can reset the media
to its factory settings and can set the file system to its default state and it
can then be used in a normal fashion. But the biggest problem is that you lose
all your important data.
Software
Tools: There are
many software tools that can help you fix this problem with your media.
Although the chances are less but it is still a valid option.
So now that
we know what safe removal is, let us talk about the other problems.
“I did a
safe removal request, and then I waited and waited but nothing happened.” It
happens and this is another reason why people hate this safe removal because it
never ends. But what could be the reason for this never ending.
The
operating system need to stop any operation on the media before it tells you
that the drive can now be safely removed. But there are applications that are
beyond the reach of operating system like your anti-virus. The anti-virus
starts checking your media for viruses and this can go on for a long time
without you suspecting it as it works in the background. Now when operating
system checks for any application that is manipulating your drive or
controlling it, it finds your anti-virus and gives you the message “This device is currently in use. Close any programs or
windows that might be using the device, and then try again.”
The solution
is simple, if you get such an error try opening such possible applications,
like your anti-virus, and check whether it is scanning this particular media.
If so, stop this operation and try removing the media again.
Another
reason for this error could be an open file/folder or an application that is
situated in your media. Just close this and eject your media, there will be no
error.
If any of
this is not helpful, you are still left with a final shot in your gun – a
proper shut down. Yes simply shut down your system and
remove the media now, it is safe. This works because when the system shuts down
it closes all the running programs, be it your anti-virus or anything else. So
now you can safely remove your media without any fear of damaging it. But mind
the word proper, do not
just plug out the power or reset it, go for a proper shut down.
This option enables you to just plug out
your media without any safe removal formality. Although it
is a default option in the system but there are chances it is disabled. Let’s
check for it and if not then enable it. Here are the steps:
Step 1: Plug
in the media you want to check for.
Step 2: Go
to Control panel > Devices
and Printers > Storage Media (double
click on it).
Step 3:
Change to Hardware tab and select your media under Device Functions by double clicking it.
Step 4:
Select Change settings and shift to Policies tab.
Here you
will find quick removal. If not selected, select it and press OK. That’s all to
it. Now you do not need to use the safe removal option to eject your media.
Although it
is a valid option but I still prefer the safe removal option for ejecting my
media from system simply because I think it is better and secure to perform all
these formalities. I
hope this article was of some help to you all. Your suggestions are always
welcome and thanks for reading. God bless you all.
Thank you for your clear instructions! I found that I have quick removal set already. I had been shutting down to remove external drive, because I kept getting that unsafe message.
ReplyDeleteglad i could help
ReplyDeleteI have been dealing with this for a while now and also found that I have quick removal set already. Thanks for letting me breathe easy!
ReplyDeleteThis is of interest to me, but I have no "Policies" tab. On clicking "Change Settings", it just re-opens the same window showing "General", "Driver" and "Details". I'm running Win 7 64 bit on an i7.
ReplyDeleteThe people that work for MS can't explain it simple as you. They need more focus groups.
ReplyDeletethanks for the appreciation.
