Its a well known fact that any confidential data can be erased from the hard-drive using loads of softwares specifically built for that. But what about the data stored on a CD or a DVD? Throwing them would mean that anyone who finds it can retrieve data easily, and if you are thinking about scratching them, damaging them, breaking them into pieces, then think again… You would be polluting the environment since lots of chemicals might be released by doing so.

Lite-On developed the Smart Erase technique to give users a reliable way of erasing the data on CDs and DVDs without damaging the disk. This technique is compatible to all CD-R and DVD-R disks, not only their rewritable counterparts.

Smart Erase overwrites the data contained on the disk with random characters much like the tools that can erase files or the free space of a hard drive so that the data is not recoverable afterwards. Nero 7 Essentials which ships with the retail versions of each DVD writer will have that feature build in which can be used in combination with one of the announced Lite-On DVD writers.

The new technique supports two modes: Quick Erase will only erase data in the lead in track and the first track of the CD / DVD while Full Erase will erase the full disk.

    Theoretically, whenever you do a quick delete, the data can be retrieved back. Full erase, will delete the data permanently :)

    You always make me think with your sensible questions mate!!

  • Raju

    First of all let me clarify yet again that I enjoy your questions, as I said before – you make me think :)

    Regarding recovering of quick-erased data, there are lots of ways/tools available. Just a couple of links for your reference –

    If you are looking for a tool, look for ISOBuster on Google.

    Hi, I know Nero 7 can erase dvd-r, what about an original dvd? let’s say a movie? like the ones you buy at any store I’m not interested in using the dvd again, I just want to erase what it’s on it.

    Thank you

      The original movie DVD you buy is also a DVD-R, so you can erase the data
