I know I am writting this post a little late. Anyway on April first windows played a little joke on me:I plugged in my flash dive and it made the whole OS lock up. I tried to go under the start menu and shut down my computer, but nothing happened. So I had to unplug the computer. I restarted it and I forgot to unplug the flash Drive and dumb  windows though I added a new Hard Drive. I got this message in the BIOS: 


 Checking file system on H:

The type of the file system is FAT.

 

One of your disks needs to be checked for consistency. You

may cancel the disk check, but it is strongly recommended

that you continue.

Windows will now check the disk.                        

Volume Serial Number is 632D-02DA

Windows has checked the file system and found no problems.

 

   1028800512 bytes total disk space.

       147456 bytes in 10 hidden files.

        32768 bytes in 2 folders.

      1851392 bytes in 5 files.

   1026768896 bytes available on disk.

 

        16384 bytes in each allocation unit.

        62793 total allocation units on disk.

        62669 allocation units available on disk.


 Then I restarted the computer and the same thing happened again! I have the issue resolved now, but that was one good April Fool’s joke Windows played on me.
