Ok - there are two different ways you can go about copying this.
The game is protected by Safedisk 2 (not sure what version - use cdkiller's
Protection ID on the main exe to check.
If it is Safedisk 2.4 or below, then you will need a cd-writer with "one sheep" in the EFM column on the
Clone CD supported writer's list
If it is 2.51 or above then you will need two sheep if you are to make a perfect 1:1 copy.
To make the 1:1 copy use Alcohol 120% or Clone CD - neither of them "strip" the Safedisk protection from the disk - rather they try to clone it bit for bit I would suggest using Alcohol.
So select it's Safedisk 2 profile from the list and try to make a copy (I suggest using re-writables for testing).
There may also be a secondary protection being used - an ATIP check. Simply, every CD-R has something called an ATIP which contains info on dye, manufacturer, length etc. Pressed cds (originals) dont have an ATIP as it's not needed. So the game does a simple check to see if an ATIP is present, and if so it won't play. The only problem with ATIP checking is that only CD-RW drives can do it - normal cd-roms can't read it.
So the way to get around the ATIP check is to either play it in a non cd-writer or use the "Ignore Media Type" emulation option in Alcohol (same as Hide CD-R Media in Clone CD).
The alternative way is using a crack - you say you have tried this before. Make sure you are using the correct crack for the version of the game you are using, and make sure you are putting the crack into the correct place - you will know you are right if it asks you do you want to overwrite the existing file.
BTW - the read errors you are finding are normal for Safedisk protection - between sectors 800-10000. If they take too long to read then check out the
Daemon Tools site and read it's online manual (read the Fast Dump Feature part of it). It'll show you how to use it's tool to speed up the reading of the errors.
