Safely Remove Your USB Devices with EjectUSB




Do you having hard time to safely remove your USB devices from your Windows and often encountered this error message, “The device cannot be stopped right now. Try stopping the device again later”? How can you put an end to this problem?
image
Well, I frequently ran into the same problem too last time but now not anymore after I’ve found Unlocker. You can read my previous blog entry to learn more about this small but useful utility. Using Unlocker is one of the solutions for this problem. The reason why this happen is that there are still programs that run from the USB device during the moment you try to eject the USB device.
Besides Unlocker, EjectUSB is another essential Windows tool that you can try out. This open-source program will close all programs running from your USB device and then safely eject the USB drive. Click here to see EjectUSB in action. Other functionalities that EjectUSB offers are flushing the file cache, closing Explorer windows and removing registry entries and Recent Document shortcuts referencing the specified USB drive.
To use EjectUSB, you need to first extract the content of the downloaded zip file onto your USB device. Next, you need to run the “EjectUSB.exe” from the USB device that you are attempted to eject. Then, let the program take care the rest of the task. So easy!
EjectUSB is compatible with all Windows OS. If you ask me which one do I prefer between Unlocker and EjectUSB, I will pick EjectUSB.

Manager. Navigate to the portion of the dialog box that has all your USB controllers enlisted. Right-click on all of them and delete them. Reboot Windows Vista. When Vista reboots it will detect the missing USB controllers and will add the devices automatically. This will take care of the problem if file corruption is the cause. Another means of troubleshooting a problem of this nature is to enable Write Caching.

Keep your Desktop In your Flash Drive


image In using computers everyday you likely send email, check the news, track finances. In using different computers you probably have different programs on each machine, maybe even different operating systems. Have you wished each machine had the same applications? Or that the bookmark you just added to your browser were on the other machine? Have you worried about computer viruses or your child deleting the wrong files? LivePCs can help you in each case.

A LivePC is a virtual computer. You can run a different operating system and different
applications within it than the computer normally runs. You can run this virtual computer directly
on a computer or from a portable drive on most computers. LivePCs can be found in The Lab on
MokaFive.com or you can make, and even share, your own using MokaFive Creator.

Variety


LivePCs are run from our MokaFive Player on Windows XP, Windows Vista, Intel based Mac OS X
machines, or BareMetal. You can run many different LivePCs from the Player. Have an
application you'd like to use that only works under DOS? You can have a DOS LivePC and add
that application. Would you like to run some applications under Linux? Download a Linux LivePC.
Would you like to have a safe games play space for your child? Launch a child friendly LivePC

Offline Use


LivePCs can be set for use without access to the internet. You could compose an email at the top
of Mount Everest on your LivePC to send once you are again connected to the web.

Security


LivePCs run on your computer but they are copies of the ones maintained on our servers. The
LivePC operating system and applications are kept separate from your personal data. If your
LivePC gets a virus, it will be removed when you exit and re-launch the LivePC. The operating
system and applications on a LivePC are kept clean by matching them to the LivePC in The Lab
on MokaFive.com. LivePCs are also independent. They are not able to open or affect files in
other LivePCs.

Portability


You can put LivePCs and the Player on a memory card, USB flash drive, USB hard disk, or an
iPod and take them to another machine. You will be able to take your LivePCs between Intel
based Macs and Windows XP or Vista machines. When installed using BareMetal you can run
from a machine which allows you to boot from USB.

Backups (Windows portable installation only)


Your portable LivePCs and your personal data can be backed up automatically to a Windows XP
or Vista computer. Should you lose your portable drive you can create a new one from the
backup.

Personalization


You can also create and share your own LivePCs, either by modifying existing LivePCs or creating your own from scratch. You can then register your LivePC at MokaFive.com to share
with the world or just your friends, or you can keep it private. By posting and subscribing to your
own LivePC you can be assured that any spyware you pickup in your LivePC virtual computer will
be removed the next time you launch it.

Protect your PEN/USB Drive from Virus


imageWorld is shrinking, and so are the data storage devices. One common device which every one use is USB devices like thumb drive, PEN drive, USB Hard disks etc...
After floppy disks which were earlier prone to many viruses, now it is time for USB Devices. Below are some safety precautions that you may perform before transferring data from USB devices.
1) When you plug in the USB device in your system (Desktop / Laptop), you will most likely be prompted by a popup window as shown below.
image
2) Dont select any of them, simply click cancel.
3) Goto Start -> Run and type cmd to open the Comman Prompt window
4) Now double click My Computer Icon (which is usually present in the desktop). It should show the list of drives available in this machine. Check the drive letter of the inserted USB Device. (As in above case it is (I:))
5) Go back to the command prompt and type the drive letter and hit Enter.
6) Now type the below command and hit Enter. This command displays all the hidden files and folders in the current working drive (I: Drive in our case)
    I:\> dir/w/o/a/p
7) You will be able to see a list of files, after you run the above command. In the list, check if you see any one of the files mentioned below,
    - Autorun.inf
    - New Folder.exe
    - Bha.vbs
    - Iexplore.vbs
    - Info.exe
    - New_Folder.exe
    - Ravmon.exe
    - RVHost.exe
or any other unknown .exe files that you are unaware of and you have not copied to the device earlier.
8) If you find any one of the files listed above, you are right!!! you have got a virus in your USB device. Don't panic, it will be transferred to your system and start its duties only when you start copying the files to your computer's hard drive.
9) Now that you have confirmed that you have virus in your USB device, now type the following command and hit enter
    I:\> attrib -h-r-s-a *.*
    attrib command is for displaying and changing the attributes of the files.
10) Now Delete each of the files that you were not aware of and found to be on the above list by using the below command and hit enter
    I:\> del <filename>
    For eg. I:\> del Autorun.inf
11) That's it, you did it!!!!!!!! now your USB Device is free of virus.
Note: Some viruses are vulnerable to antivirus softwares. When unnoticed these viruses sits in system registry and doesnot allow the antivirus software to locate the source file. But it generates a virus child file in all the folders of the system. Antivirus software may detect the child file and delete it, but it keeps on generating. It cannot be stopped until source virus file is removed.
