Scenario : You connect your PD to your PC, it is recognized (you get the audio confirmation) but it just does not show up in Explorer. There is no way for you to access it.
Solution : I am pretty sure that everyone in his lifetime at least once comes across this problem which is called as frying your Pen Drive. You plug in your PD, it is recognized but you are not able to access it. You open the Disk Management component of the Computer Management console (type compmgmt.msc in RUN), it shows that the drive is connected, but there is no unallocated space.
Other things about the disk look normal. It shows up in the Device Manager as working correctly, without any warnings. Googling around also does not help cos although many people have this problem where the drive starts reporting 0 bytes capacity and can not be formatted but nowhere is there a fix for it. The most common solution offered was to return the drive to the manufacturer for replacement(if under warranty) or buy a new one( they are so cheap). Well, I wasn’t going to do so until i am dead sure that the usb is totally fried and its not some crappy windows driver issue. So here’s what you do to make sure that the drive is really fried and you need a new one.
Scenario : What else ?? The same as always….PC infected by Autorun Virus….need some safeguard….you know…
Solution : Read my Previous Posts.
Ok, On a serious note, Found this new USB Protection Utility tool : BitDefender’s USB immunizer. It comes with two options : immunize your USB storage device or SD card and Immunize Compute. More details Below.
General Scenario : You have had a look at many methods to protect your USB but find it a bit complex and confusing and dont know which methods to implement…
Solution : As always…dont worry...i’ll be there for you…I will give you a sketch of the measures that i had in effect for my PC(I say “had” because thats what i used in my XP system but now i’m on Win7 and don’t require much of them except few) and you can use it if you like it.
First of all, i had installed Panda USB Vaccine (Method 3) so that took care of auto run of viruses from my pen drive and from an external pen drive on my PC. The only problem i faced with that was that i could not implement Method 1 or Method 2 which i wanted to.
I also had USB Safely Remove installed because it not only resolves those “device is locked” scenarios but also because of an added less known feature – the ability to run scripts on connection and removal (This features are also available in Zentimo). I had modified its settings to run the enable write-protect script (Method 4) on connecting a new device and run the disable write-protect on removal. Also i used to keep the disable write-protect script on my desktop in case i want to copy some files to the PD (I still do!!!). On a related note, I hope all of you have made use of the Free Zentimo Lifetime License Promo.
Note : After reading this method you might feel that you can carry the scripts on your PD and running it when connecting it to external PC via autorun, there is a chance that it might not work and give you a false sense of security. And if it does work and then you might forget to run the disable script and it will pose a problem to the external PC User…..however if that IS your intention, then full steam ahead 🙂
I troubleshoot people’s PC problems and hence carry a PD with a lot of portable and useful tools which i use to troubleshoot people’s infected PC. I would not be copying anything from their PC and would not want anything to write itself to my PD, so i use the ” fsutil trick” on my PD (Method 5).
Since i’m not using USB Safely Remove or Zentimo on my Win7, i have created a batch file to make sure that i do not encounter that “cannot safely remove hardware as it is currently in use” error (Method 7). Till now, i have not had to use it (Touch Wood!!!).
This constitutes my summary of Protecting Your USB….mind you that this was not only the arrangement that i used on my XP but also the customisations i currently do on the PC’s of clients for whom i do a fresh install of XP and it does work…..atleast for most of them…after all Stupidity has no cure 🙂 :P.
With this, i have covered most of the issues regarding protecting your USB….If i find more i will surely update this..I hope that you all found this useful…Post soon….Stay Sharp!!!
Boy, Talk about getting Lucky…..Continuing our USB protection Series….Here is your chance to get it… in a different form. If you remember, in my last post, i mentioned a very popular program called USB Safely Remove……Zentimo is the successor to the very popular USB Safely Remove, a program that allows users to manage external devices that connect to the computer via USB.

Scenario : After you have stopped the device, but still have not unplugged it and then you remember that you forgot to write a file to the external drive. In order to do it, you have to physically reconnect the device, however it’s quite inconvenient if the USB Port is on the rear panel of your PC.
Solution : This can be an issue and if you want to remove this by means of an external software, then i will highly recommend “USB Safely Remove” but if you do not want to rely on external software then here is what you need to do to remount the device back.
1. Right click My Computer and select Properties (or simultaneously press Win+Pause/Break key). In System Properties window, go to the Hardware tab and then click the Device Manager button. In Windows 7, you can click the Device Manager link on the left hand sidebar. You can also type “devmgmt.msc” in run window.
2. Expand Universal Serial Bus Controllers.
3. You will find a device that has a yellow color exclamation mark. Right click on the USB Device and select Disable. Again right click on the same USB Device that you’ve just disabled and this time select Enable.
Agreed that this method might feel cumbersome if the USB port is easily accessible cos unplugging and reinserting it wil be way faster but this can save you from bending your back and trying to reach the back of the case if its on the inaccessible rear panel.
Scenario : You want only those USB’s that you know be allowed to be connected to your PC
Solution : That is a valid concern cos we all know that to exploit a PC it is sometimes enough to just connect the USB device to the PC
So today we are going to look at a “Freeware”( Yayy!!!! ;P ) program called “USB Waecher”, which is German for USB Guardian. I like the way that this program works. The S/W uses a white-list to determine if an USB device may be allowed to connect to the PC. Devices not in the white-list are not permitted to establish the connection unless they are white-listed.
It might be a bit of a pain for English people ( and i don’t mean residents of England 😉 ) as Part of the information is displayed in German, with no option whatsoever to change the interface language, however you can very easily use the program even without understanding German. We only have to concentrate on the menu on the left side which is denoted as ” Erlaubte Geräte “, which means allowed devices. This lists all USB devices that are permitted to connect to the PC so that they can be used. All devices that are connected during installation are automatically added to the white-list.
To add new USB devices to the white-list by clicking on the + icon in the toolbar of the application, or by right-clicking on Erlaubte Geräte and selecting Gerät hinzufügen (which means add device). This displays a wizard which is completely in German. Not a big problem though as you need to click on Weiter (next) in the first screen to select the USB device that needs to be added to the whitelist on the second. Just select the device or devices and click Weiter once again. Click Fertig stellen (finalize) on the last screen of the wizard to add the device to the whitelist.
To remove a device just right-click on the USB device and select Delete from the context menu.
Supported Operating Systems:
- Windows 2000 and Windows 2008 R2 (32/64)
- Windows XP to Windows 7 (32/64)
The program can be downloaded directly from the developer’s website.
