Fix : Hard disk suddenly shows Raw partition, not accessible in Windows 8 , 7 , Vista , XP

Windows cannot access this drive, do you wish to format it, is the message that you will receive when you try to open your hard disk drive or a partition on your HDD. This post will help you fix this issue in a few simple steps. This guide will also help you recover your data from the hard drive which is now detected as RAW in your Windows PC. Recently my 2 TB Seagate Go Flex drive started to show RAW partition & I feared loosing all my data, below mentioned is the method that worked for me.

Pre-requisites for this method:

  • Windows Installation CD / DVD /USB ( Windows 8 , 7 , Vista )
  • OR
  • Windows 8 , 7 repair disk
  • Test Disk – Click to download ( Use this, if the problem hard disk drive is not your primary drive )
  • OR
  • Parted Magic –Click to download the ISO file and burn a CD ( Use this ,if your primary hard disk drive is the problem hard drive and you lost your operating system )

Note: Do not use this method on a Solid State Drive

Test Disk usage remains the same from Within Windows & from Parted magic

If you wish to use parted magic :

  • Burn the disc image to a CD or make a Bootable USB
  • While booting, Choose option 1. Default settings, Run from RAM
  • After the booting sequence is complete,
  • Locate and click on the Terminal Icon ( Bottom left area )
  • type testdisk & press Enter


Test Disk Usage :

  • You can choose to either create a Log or not ( depends on you )
  • testdisk1
  • Select the hard disk drive with the Raw partition from the given list & press Enter
  • testdisk2
  • In this step, check the hint part & select accordingly ( for me it shows Intel )

  • Press Y to write backup boot sector to the primary boot sector
  • But,
  • If in case both your boot sectors are BAD
  • Select Rebuild BS & press Enter
  • This process will take some time to complete, Press Y in the end to execute
