750 gb harddisk How space should be system get deducted


I have taken a 750 Gb Hard Disk 53 gb space is been deducted. 

its showing 697 gb  for storage.

need to know how much space is usually get deducted external hard drive.

Read this http://wdc.custhelp.com/app/answers/detail/a_id/615/  It’s how Windows calculates the space you haven’t lost any.


This happens with all drives, this is due to an issue with the translation from Bynary to decimal, however, this does not mean that the space that is not showing is not available for you to use it. I found an article that explains this issue with more details.


Oh thanks! I was having the same issue and was wondering if I got a defective unit. Thanks for the information.
