The Safest Way to Erase Your Data Permanently!
Problem: many sensitive data is stored on write-once CDs or DVDs. 
What do you do with your stack of discs containing out-of-date, but confidential or personal files?
These discs can be physically destroyed and thrown away, but it is not 100% guaranteed that the data is not retrievable.
New Lite-On DVD writers offer the solution:
SmartErase
The easiest and safest way to erase data permanently!
SmartErase is implemented on the latest generation 22x DVD rewriters from Lite-On
A DVD/CD writer uses laser power to create "recorded marks" on the track surface of a recordable media.
The difference between "marked surfaces" and "unmarked surfaces" is then interpreted by a DVD/CD reader as "1" and "0", which in turn form data strings
.
That's why even after you break or scratch a disc, the data could be retrieved from the undamaged parts of the disc with special technology.
How does SmartErase work?
SmartErase uses the same DVD/CD writing laser to mark the recordable surfaces.
It covers 100% of the surface with meaningless random data.
Because the whole track surface is marked, no technology can retrieve the data originally stored on the disc.
This is how SmartErase works. SmartErase will rewrite CD-R/DVD±R with random meaningless characters so that the original data and the disc will be "destroyed". Once you “SmartErased” a disc, you don’t have to worry about that someone will access the confidential data from the disc you dumped.
There are two methods to erase your disc:
1 Quick Erase:
Quick Erase erases only the information stored in Lead-in area and data stored on the first track. Once the information in Lead-in area is destroyed, the drive cannot find the location where the data is stored. Therefore the data can not be read. Though some data recovery may have the chance to recover data from areas where data has not been overwritten.
Pros: Takes less time to destroy a disc.
Cons: Data on the disc may have the chance to be restored by data recovery software.
2 Full Erase:
Full Erase erases all the disc, from Lead-in to Lead-out area of every session on the disc. The data on a full erased disc will no longer be restored.
Pros: Fully destroy the information and data on the disc. Data on the disc will no longer be restored.
Cons: Takes a longer time to destroy a disc.
