ProtectDISC
From Redump Wiki
CSS/CPPM based copy protection for PC Games. Like with DVD-Video keys are automatically decrypted by Redumper and should be included in protection info. Early versions (v6) overlapped that of ProtectCD/DVD and might lack a key in favor of still using DPM.
Sometimes a remnant CSS/CPPM key might be identified as ProtectDISC by BoS despite executables not being protected.
Redumper currently does not combine the CSS/CPPM key with the disc image. To get a working dump use DT Pro and CSS plugin
(DT Pro + CSS plugin -> choose New ProtectDisc profile -> PD from v6 and on, CSS plugin required, for DVDs only)
