If primary hard disk partition contains an operating system, chances are that you no longer bootingup- because the boot sector is damaged. If the hard drive is a secondary drive (data) or can connect to another computer in its secondary channel controller (usually where the CD / DVD is connected), the following symptoms would be observed:

     1. Windows Explorer or Disk Manager displays the first primary partition as "RAW" (unformatted) and Windows XP will display:, The unnidad x disk is not formatted would you like to format it now? and Windows Vista / 7/8 The drive is not formatted Do you want to format it?     [You should never do so without knowing why!]



In Linux appears with Linux mount command displays wrong fs type, bad option, bad superblock
 
     2. A logical partition is missing. So in Windows Explorer logical drive is no longer available. The Disk Management Console for Windows now shows only "unallocated space" where once was located this logical partition.
