**FutureProof** · 15-11-2003

Creating a working SafeDisc backup in DiscJuggler depends on the pre-gap being read and written 'as-is'. These are some results, working from the ASUS CRW-5242A FW Rev 1.0, a known pregap reader/writer (all ASUS two-sheep writers are pregap killers). The pregap is only an issue for DJ; the popular burning apps reproduce the pregap in a way that should not be of a concern to the user ... or should it?

Using DJ allows you te create a backup that requires no thirdparty assistance (Daemon Tools emu, CloneCD "Hide CD-R Media"), if this is what you desire

The objective of these tests is to determine other pregap reader/writers and assess whether emulation, of some description, is required.

Game Title: The Sims Superstar expansion; original install.
Protection: SafeDisc 2.90.040
Program: DiscJuggler V4.10.1084-STD2 (ASPI Shell = pfc.sys)
Reader: ASUS CRW-5224A FW Rev 1.0

Writers used are known burning app 'two-sheep' burners, or, are capable of correct EFM encoding of regular bit patterns (ie Weak Sector writers):

Toshiba SD-M1202 CD-RW/DVD-ROM combo FW Rev 1023:

Toshiba SD-M1402 DVD-ROM - does not work with or without "Hide" and Daemon Tools
Toshiba SD-M1202 CD-RW/DVD-ROM combo - works with DT, works with "Hide"
ASUS CRW-5224A - works with CCD "Hide" does not work with DT emu ... ah! But wait ... eject the disc, reinsert again, and it will work
LITEON LTD-163D - works without DT emu and CCD "Hide".
Observations: the 1402 does not like an ASUS image; the 1202 can write the pregap correctly as the backup works without emu in the 163D DVD-ROM

Next on the list are:[list=1][*]LITEON LTR-24102B[*]LITEON LTR-32123S[*]LITEON LTR-40125S[*]LITEON LTR-52246S[/list=1]If you get a backup failure message on execution, it pays to reboot, as sometimes the guard module stays memory resident and will detect the backup (I have tried this, seen the process and got things to work). Before doing that, try ejecting the backup and starting the game again. If you change emu at any point, turn off all emu, eject the backup, turn on your emu of choice and THEN close the drive tray - the emu tool needs to grab control of the disc before the OS

Stay tuned
