| Pen drive problems? |
Pen drives or USB flash drives are now most common way to transfer information from one place to another in bulk. Statistics say that, use of pen drives than traditional CD/DVDs is increasing at very fast rate. But, at the same time problems faced by users are increasing due to lack of basic knowledge about handling them. This post concentrates on problems faced by users and their solutions in context with pen drives.
Virus affected??
The major problem is people don’t know whether their USB drive is affected by virus or not. Careless plugging of infected drives leads to spread of virus from one machine to another. One of the simplest ways to check whether pen drive is affected or not, is plugging it on Linux operating systems. Linux OS lists all files independent of whether it is a virus or normal file, also it is not affected by many of the viruses on windows OS. If you see the files with name autorun.inf, new folder.exe, recycler.exe etc. (Which are not common types that you use) then just delete them. If Linux is not available then you can still do this with Windows OS. Here is how…
Go to Start -> Run. Type CMD and hit Enter.

| Command prompt |
A command prompt will open. Now move to current drive directory by entering CD\
Next, type drive letter of your pen drive with colon at end. For example: – If your pen drives have an access with letter G then type G:
Type dir/w/o/a/p and then Enter. This will give list of all files information in a wide list. Check this list for above mentioned files to check infection.
Double click on drive shows open with:
‘Open with’ window appear when you double click the drive letter or search window appears when you double click pen drive icon. These are common problems faced by user when autorun.inf is infected. The fix to this problem is-

| ‘Open with’ dialog |
- Double click on my computer on Desktop. Go to Tool and select “Folder options”. Select View -> Show Hidden files and folders and uncheck Hide Extension and Hide protected operating system file.Click OK.
- Now, Open Windows Task Manager (ctrl-shift-esc) and select the Processes. Find wscript.exe and then click End Process.
- Then go to Start -> Search and search for “autorun.inf”. Delete all the files that contain the text MS32DLL.dll.vbs (the virus) by pressing: SHIFT + DELETE. Also delete the virus from the system (C:\WINDOWS\ MS32DLL.dll.vbs)
- Next step is to edit the Registry. Go to Start -> Run -> Regedit and hit Enter.Select HKEY_LOCAL_MACHINE –> Software –>Microsoft –>Windows –> Current Version –> Run. Find there “MS32DLL” and delete that entry.
- Then, select HKEY_CURRENT_USER –> Software –> Microsoft –> Internet Explorer –> Main. There you find “Window Title “Hacked by Godzilla”” and you should delete that entry. You can close the registry now.
- Again Start –> Run -> gpedit.msc hit Enter. Then you will open “Group Policy”.Select User Configuration –> Administrative Templates –> System –> and there you will double click on “Turn off Auto play” .The window there you should select “Enabled” and select “All drives”. Now you can close the Group Policy.
- Now, go to Start –> Run -> msconfig -> Startup. Find the file MS32DLL, choose Enable All, and then uncheck “MS32DLL” Click Apply then OK to close. Then exit the “System Configuration Utility” and select “Exit without Restart” when prompt.
- At last, go to My Computer -> Tools -> Folder Options -> View. Select Hide Extension and Hide protected operating system file and don’t show hidden files and folders. Then empty the “Recycle bin” and “Restart” your computer.
That’s it!
The device ‘Generic volume’ cannot be stopped right now:
Warning occurs because one of your files or program from USB drive is still in use by OS and that’s why it is refusing for a safe removal. This can be solved by closing all explorer windows, refreshing 5-6 times and then try to remove drive again. If this trick doesn’t work then follow these steps: -
- Go to My Computer -> Right click on drive icon
- Select hardware – > Device -> Policies
- Select Optimize for quick performance option there.

USB drive will not appear in your Computer:
This can happen to you, as you plugged-in your USB drive to your computer and Windows detects the USB drive but it does not show the drive icon for it in My Computer. The culprit here is Windows which is unable to allocate Drive letter for your USB drive. The Fix is we have to change the drive letter of USB Drive that is already shown in disk management service.
- Go to Start -> Run -> type diskmgmt.msc and hit Enter.
- Select USB Drive -> Right click on it. Now, click Change Drive Letter and paths
- Select change and from drive letters drop down menu select a letter that is not allocated to other drives in My Computer and click OK and click yes to confirm to continue from the warning message.
- A new drive letter is allocated to your USB Drive and will be shown in My Computer.
- Now you can access the USB drive without any problems.
Double click on drive opens new window:
Expected behavior of a system is that each drive opens in the same window until a user has explicitly set the option Open Each Folder in Its Own Window under My computer -> Tools -> Folder Options. A drive opens in new window because virus tries to edit file folder to add more context menu items. This problem can be fixed by one of the following methods.
Method 1:
- Open Start -> Run and type regsvr32 /i shell32.dll. Click OK
- A message DllRegisterServer and DllInstall in shell32.dll succeeded will appear. That’s it!
Method 2:
- Open Start >> Run and type regedit
- Go to HKEY_CLASSES_ROOT/Directory/Shell. Double click the default key types none and press Ok.
- Now navigate to HKEY_CLASSES_ROOT/Drive/Shell. Double click the default key types none and press Ok.
Tips for using a Pendrive:
- Always insert pen drive at 90 degrees from port.
- Avoid formatting unless it is too worse condition.
- De-fragment a drive once in 15 days.
- Use safely remove option whenever you want to unplug your USB drive.
- Protect Serial Number from glazing over.
- First scan whole drive for virus removal before opening in explorer.
