Introduction of wiping
data:
Wiping data from the hard
disk refers to the context of overwriting the data with zeros or
random characters thus rendering it illegible to read. According to
the dictionary knowledge wiping is the synonym of deleting but
actually deleting the data means removing the data from the file
listing and not from the computer. So wiping is a technique, which
uses certain algorithms to permanently erase, the hard drive data
from the computer, which cannot be recovered later.
Why wipe data from Mac
hard drive:
Before handing the used
hard drive to another person or giving away your Mac, it is very
important to delete the confidential and personal files so that
nobody is able to retrieve the data afterwards. Formatting the disk
will not accomplish the task of deleting the actual data from the Mac
computer or hard drive. Same with using ‘emptying trash’ command,
which only removes the data from the OS X but doesn’t wipe it from
its original location. Data shredding is needed for the security
transaction of the hard drive to any other stranger.
Benefits of wiping data
from Mac disk:
=> Permanently erase
the Hard drive data.
=> Completely erase all
system entries, log files and all sensitive information created by
the OS.
=> Wiping will lead to
ensure free spaces.
=> Data is securely
wiped and finally didn't leave any traces.
Wipe Using OS X Secure
Wipe Mac:
Eradicating credit card
information, chats, Banking passwords, financial information,
personal files is not enough with the action of removing the data
from trash simply. Making the confidential information inaccessible
in Mac computers require the certain steps to follow:
'Secure Empty Trash'
feature: First of all there should be one file or folder in the trash
to make the option of 'Secure Empty Trash' available. Then just
press-hold the Command button on trash icon present on the dock to
ensure the visibility of the option. Right click on the required
option will overwrite the data ultimately resulting in unreadable
files or folders. Also another way to access this option is from the
Finder menu. This is a knowledgeable practice to securely erase the
files & folders residing in trash.
To secure wipe Mac
partition:
=> Launch Disk Utility
and then select the hard drive that you want to erase.
=> Clicking on the
erase tab will ask to choose one of the security options button. =>
The four security options are:
- Nothing
- Zero out data
- 3-Pass Erase
- 7-Pass Erase.
First option is not to
erase any data. Zero out data will overwrite the data once. Since the
more overwrite is there, the maximum data security is maintained. So
3-Pass will take three times longer to overwrite the data whereas
7-Pass erase will take seven times longer to do this task
effectively. The criteria of choosing the desired level depend on the
data.

wiped completely with the zero possibility of recovery chances.
