There are some trick you can do. To see what protection it is on the cd. By not using a tool.
SecuROM:
All SecuROM protected CD, have "SonyDADC" label in there cirkel on the CD. it's small lether so might need a big glasses or good eye
SafeDisc:
All SafeDisc have temp files on it, but SafeDisc one have .icd files can be found directly in the CD.
SafeDisc 2, well you can scan the .exe file all SafeDisc 2 protected CD have there .exe unpacked. But there are also 1231415.tmp and so on.
SafeDisc 3, it's says that they also have write a singanture on the CD inner cirkel..should be label something, SafeDisc, Macrovision, Macrovision SafeDisc or something.
