How to prevent copying files to USB drive without disable USB port

Today early morning my friend called me for an urgent help. He is working as a network administrator for a small company and he want to disable copying content from working computer to USB drives (pen drives). I told him simply disable the USB port and fix the issue. Then he said according to the company policy he cannot disable USB port and the computer should read files from the USB drive. So in a nutshell he want to read files from the USB drive on his company computers but don't want to copy files from his company computer to the USB drive. He is in a confusion that is it possible to block writing files to the USB drive without prevent reading from it.


I too at first confused with this strange company policy. Then I realize it is very simple to do. We can enable write protection on USB by GP edit or registry edit. I told him to enable write protection on USB in all the working computer and that will resolve the issue. It is very simple to enable write protection on USB ports in registry.


Prevent copy files to USB drive without disable USB



To perform this we need to edit some registry entries. To do this registry edition follow the steps below.


1. Click on start and go to Run

2. Type regedit on run window and click OK

Now the registry editor will be opened. Now follow


HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

3. Create a DWORD value called ‘WriteProtect‘ and set it to 1.


To disable write protect on USB drives change the DWORD to 0.

What is Overclocking and how it reduces the cost of system upgrade

The title of the post is just interesting as it says the importance of overclocking our computer and increase the performance of the system than the manufactures expectations. But before we start overclocking it is better know what actually mean overclocking. Overclocking is the tweaking of your computer and optimize it for better performance. In simple words by overclocking we are utilizing the maximum possible performance of our computer. In case of running applications on our computer which requires more computing power than our computer offered , we should think about overclocking our system. It is always better have a try to improve the performance of our computer than the costly hardware upgrading.

Risks and negative side of overclocking

Overclocking has some negative side too. They are:

1. Warranty issue

By overclocking we are running a computer component at a specification higher than rated by the manufacturer and it may affect the warranty issued by them. In case the device went wrong the vendor may refuse to help us by saying what you did is against the warranty policy.

So it is advised to perform overclocking on old computer if you are not an expert.

2. Processor stability

Overclocking may result system instability. So it is always better check the performance by increasing the rate of speed slowly.

3. Heat generation


Heat generation is an another issue with overclocking. By increasing the performance of the computer equipments the energy consumption will increase. This result over heating.

As a precaution we should daily check the heat sink and cabinet fans and make sure they are working properly.


Even though there are some negative sides I always encourage you to overclock your old computers and increase the performance of the system. Even if you fails it is just a good attempt and will be an asset your tech life.

Unable to start your computer - Disk Boot Failure

On the week end days I was a little bit busy with troubleshooting my friend's old desktop computer. His computer was a dead one and I want to make it alive. He had not been using this computer for last 4 months. We started a fresh installation of Windows XP on his computer as the issue was crashed OS. After reboot we couldn't make it to run ,we received one Disk Boot Failure error message . We just followed the below troubleshooting steps and isolate the actual reason of the issue. Here I am presenting the way I troubleshooted the issue. I used some of my hardware experience and many online tutorials.

Steps to fix the issue Disk Boot Failure


The steps we followed are:

1. Log on to BIOS and reset the BIOS settings

We heard that if the booting option in BIOS went wrong we may receive the error message Disk Boot Failure and cannot boot the computer. We press the [F2] just after power on the system. At first we failed to log on to the BIOS but in a continues attempts some how we get in to the BIOS. Fortunately there was no BIOS password , otherwise it will be a herculean task to log on to BIOS in a corrupted computer.


[ In case if you need to log on to BIOS and forgot the BIOS password follow the steps in the post given below.

Forgot BIOS password and cannot log on to it


]

We reset the boot option and set hard disk the first priority.


2. Unplugged the devices and reconnect it


The second option was make your hands dirty. We opened the computer case and disconnect the BUS and cleaned the devices. Yea a lot of dust was inside the cabinet. We cleaned it and reconnect the devices like hard disk,DVD writer, RAM ,mother board etc. Some after this step the stupid computer start run without any issue. So our assumption is the issue was with some loos connection or dust issues.

Here I am not going to stop writing as I am extending this post with other available troubleshooting steps which we didn't try.


3. Presence of non compatible hardware devices

It is possible that after connecting some non compatible hardware on your computer you may receive the error message Disk Boot Failure and the system fails to boot properly. So it is always advised to disconnect the last added hardware and check for the issue.


4. Corrupted OS or improper partitions

Some times due to the improper partition of the hard-disk may cause this error. Another important reason is corrupted Operating System. If the OS installed on your computer corrupted ,you cannot boot your computer. These two are very important possibilities.


5. Failed Hard disk


Another reason for "Disk Boot Failure" is hard disk failure. If the hard disk drive went wrong you cannot load OS to the memory and the system boot will fail. So to check this error you need to check whether the hard-disk went wrong or not. You can perform it by connecting your hard disk as the slave of another hard drive and check if this disk is detected by the computer or not. If not it is the time to purchase a new hard disk.


6. Mother board issue.

Another rare reason is mother board failure. Some times this error message will come as a result of mother board issues. It is advised to check your mother board if the issue is not related to hard disk and other possible reasons mentioned above.

Migration to Norton Internet Security 2009 from NIS 2008 version

Yesterday night I received one promotional mail which gave me a free chance to install Norton Internet Security (NIS) 2009 version on my computer. Till that time NIS 2008 was running on my computer. I found it is so easy to install NIS 2009 version on my computer compared to the previous version. But after installing the NIS 2009 , I found some difficulty on my computer. So I started talking to one of my friend who is really an expert in AntiVirus related stuff. He gave me some suggestions and easily I fixed the issue with Norton on my computer. The suggestions he gave me are:

Safe steps to install Norton Internet Security on your computer

The major precautions we need to take before migrating to the newer Norton products are:

1. Uninstall previously installed Norton products

Here I installed Norton Internet Security 2008 on my computer and I uninstalled it using Norton Removal Tool. I recommend you to use Norton Removal Tool to uninstall Norton products from your computer than using conventional Add/Remove programs.

2. Restart your computer

3. Remove LiveUpdate from your computer

NIS 2009 is not using a different LiveUpdate to update the product on your computer. LiveUpdate is integrated with the NIS 2009 and we don't need to keep the conventional LiveUpdate on our computer.

We can remove LiveUpdate from our computer using Add/Remove Programs.


4. Removal of Norton Remnants from your computer

If you are not sure whether the previously installed Norton product is fully removed from your computer , you can run Norton Removal Tool in safe mode.


After following the above 4 steps we can install the fresh copy of latest Norton product on our computer without having any issues.

I forgot my Laptop password and I can't access my files

Yesterday night my friend called me. His sister just finished her project work on her laptop and to protect the files she changed the password of her Laptop. After changing the password she is not able to log on to her Laptop. It is a Windows XP Laptop and only one user account is there. What she was telling is the Laptop is not accepting her new password and old password. She told me, tomorrow she should present the project in her college and there is no backup files. At first we tried some possible passwords and they were not working. Then I told them to restart the Laptop and when the Laptop start booting press [F8] button. My intention was just to get the default Windows administrator account and hope there wont be any password set. They started booting their computer and get in to the safe mode. They saw the hidden Windows admin account and log on to it[ Thanks to the guy who installed OS on her laptop as there is no password].

[ If you need to enable Windows hidden administrative account on your computer click on the link below.

How to enable and disable Windows default administrator account ]

Then I ask her to find the data files in the stored location. She said it is word file (May be project description but that is non of my business) and not seeing that. I told her to use the search function to find the file but the result was null. Then I asked her where did you saved the files? She said she saved the files on desktop and now no files present. They opened word and try to find the saved files location, but failed to find the files saved on desktop. The I asked her "do you remember the password hint?"


[To know steps to reset the Windows administrator password click on the link below.

Steps to bypass Windows Administrator account password ]

She said yes. Then why should we waste our time go to user accounts and reset the password using the password hit. She did that and the password of her user account has removed. Then she restarted her laptop and successfully log on to her account. She was so happy when she was able to find the saved files.
