If you are confused with the terms-deletion of the file using the Shift+Delete, File Wiping, File Shredding and Drive Wipe and eager to know which among them is the best for maintaining the confidentiality of data before departing your hard drive, then here is the way to judge it out. There are major differences between these methods, just have a look:
· Deletion of the file: When you hit Shift+Delete key to remove the file from the system, then this is only the illusion that the file is deleted. This is only the operating system which can’t search it out due to its reference deletion from the file system, but the data recovery tools can end this job very effectively and for sure. Thus the complete obliteration of data is not made with the delete key and thus creates several risks of falling in the creepy hands that can make this data to work for their profit.
· File Wiping: This technique allows you to wipe the particular set of file. In this method, the data area of the file is overwritten with the nonsense digital information. But when the user is intended to wipe hard drive as a whole and is not ready to spend lots of business hours in selecting the files individually and overwriting the file , then this technique doesn’t worth.
· File Shredding: This process is similar to shredding the piece of paper in the shredder. But as the shreds of paper still contain the data and thus can be reconstructed with the harsh effects to you.
· Drive Wipe: This is considered as the best way out to remove the critical information from the hard disk. Wipe hard drive is the most effective way to accomplish the maintenance of data confidentiality. Under this technique, whole of the hard drive is undergone the overwriting with the garbage binary data. Now as none of the data which has been overwritten, even once, is quite impossible to be recovered. This is just like burying whole of the space of hard drive with the nonsense information. The multiple passes will work more effectively.
Thus this is recommended that when the user wishes to delete the information permanently and safely from the hard drive, drive wipe is the best way to go and for this purpose various software are available in the market. These wipe hard drive utilities have the varying set of features.
