I just recently bought Nero 2015 and found the SecurDisc option interesting. I currently used DVDisaster to add recovery to a DVD's but SecurDisc seemed a little better since its built into Nero and is faster to setup. But before I took and jumped in the SecurDisc pool I decided to run the same test I used with DVDisaster to make sure I can actually recover data after bad disc damage. What I found was that the software failed to recover all the damaged files from the disk even though it said "Recovered". I repeated the test using a much less aggressive damaged disc and still got corrupted files back from the damaged disc.
In DVDisaster with 25% of the disc space reserved for recovery it could
recover a DVD from the damage I left. I bet 10% would have been enough.
SecurDisc failed when 75% of the DVD is recovery information. 75% should
be enough to recover from some very bad disc issues. That is like
writing the same info 3x on the disc. Nothing is recovered and at no
point have I seen that SecurDisc even work beyond returning corrupted
Seems that this software was designed 7 years ago and simply was added for a bullet point. Nothing shows me that its even a valid recovery tool without a external application like Multipar to help recover the damage SecurDisc fails to correct. I'm sticking with DVDisaster.
