			SecuROM discs with active protection always have one single error in the data track, always in the third from the last sector.

			Discs with 99 SecuROM sectors dumped by DIC may have an erroneous offset of -59 reported initially in _disc.txt, followed by the correct offset of -647. Any PC disc with reported offset -59 should be carefully checked as a result.

			==== Correct sector count ====
			Different versions of SecuROM have known sector counts as follows:
			* Pre-v3 - 216
			* v3 - 90
			* v4 - 99
			* post-v4 - 11

			Any dumps with SecuROM should be checked carefully to ensure that the "SecuROM data" section contains an accurate number of sectors.

			If not, the dumper should be asked to redump using DIC with the <code>/np /nq /nr</code> flags, and to then manually extract the SecuROM sectors from the .sub file with <code>psxt001z --libcrypt</code>. It may also be worth asking for a dump to be done with IsoBuster or CloneCD to verify.
