Well, what is the difference between software and hardware protection?
Its all about freaking 0/1.
Therefore, software protection is a hardware protection and hardware protection is software protection..


No, NO, NO!! (grrr)

But I'm glad U asked..

Software protection is about the way data - the "freaking 0/1s" - is coded, ie. the data format (bad sectors, weak sectors, dummy files, invalid TOC, tracks shorter than 4 sec, altered pregap, modified or special subchannel data, etc...). Such data alteration can be carried out simply with appropriate protection/backup software.

Hardware protection on the other hand deals with the way the data is arranged, ie. data placement on the surface on the disk - for example in the case of Securom 4.8+ the lands and pits are shorter in some places, thus increasing data density on the disk. Therefore reproducing such density calls not only for proper software, but also special hardware. Without it, only emulation is possible (eg. twinpeaks)

Get it?
