How To Recover Disappeared/Hidden Files & Folders From Pen-Drives,Hard-Disks Due To Virus

Hello My Dear Friends,

I'm Sujoy, and today I'll tell you how to recover your files/folders from pen-drives(flash drives),hard disks,memory cards which got disappeared/hidden due to virus or some other reasons. Remember,this trick can't recover files/folders which disappeared due to file system errors or disk crashes.

Yesterday,my friend brought his 2TB Seagate external hard disk to me,complaining that some of his folders are not showing in windows explorer,but total used space hasn't decreased.

Then I opened my favorite Command Prompt and fixed the problem! How? Explained below-

1. For Windows Vista,Windows 7 and Windows 8 users,connect the pen-drive or hard-disk to your pc and double click to open it,as usual; or right click on the drive from My Computer,then select explore.

Then press & hold the SHIFT key and right click on any blank area & select "Open command window here", a command prompt window will open.

For Windows XP users,press & hold Windows key,then press R key, ie, Windows+R. Type cmd and press enter,command prompt will open. Then type device's drive letter followed by a colon. 

Example- H:    ,as my pen-drive is now H drive.

2. Then type this command attrib -s -h -r  and press the TAB key. Each time you press the TAB key,a new folder name will appear beside the attrib -s -h -r command. When you see your desired folder name,which got hidden,press enter key,the selected folder will be visible & will appear in the explorer window. If not,just refresh the drive window,by F5.

For example,a folder named "project" got hidden on my 4GB pen-drive. You can see in the screenshot,no folder is visible on pen-drive,but used space is 439MB.

Then I'll open command prompt and type attrib -s -h -r   and press TAB. I'll see folder named Project appeared on screen beside attrib -s -h -r. I'll now press ENTER. And magic!! The folder project will appear on pen-drive! Now I can double click it and see the contents!!

One tip- Fully scan your pc with a good and most importantly,UPDATED Anti-Virus after that,so that such problem doesn't appear again.

So,this was for now,next time I'll come with a more exciting & useful tutorial for you. How was this tutorial,let me know!

How To Make A Wireless FM Antenna For Any Mobile Phone

Today I'll tell you how to make a wireless FM antenna for any mobile phone which have 3.5mm earphone jack.

Step 1- Take any cheap 3.5mm earphone(which you could destroy!).

Step2- Cut the earphone wire from from top of the pin.

Step3- Take the pin and remove all plastic insulation attached to it.

Step4- Take a small length of copper wire(about 10-12cm long).

Step5- Attach one end of the copper wire to the top pin of the jack, if you want,you can solder it also. Now connect the jack to your phone and open FM radio,tune in to your favorite channel. Depending on the signal strength at your house,your phone should catch FM signal.

Step6- Your FM antenna is ready, you can attach other end of the wire to the pin above the flat pin,as shone in the figure below. That will make a loop.



Step7- If you want,you can cover the portion above flat pin with tape or thread for grip and for decoration,as I did.
