After making a lot of tests with games of Safedisk 2.9x and safedisk 3.x these are my points of view and solutions:
- LG and ASUS cd-burners (newest models) can make perfect backups of safedisk 2.90 and 3.1 for any theorical device (99.99% of cases works)
-Old plexwriter 8/20 and its brother 8/2/20 can make it too, but it is possible that in some dvd-writers detects two weak sectors on both last revisions as defective but in most of the cases works without probs (however toshiba dvd-roms work and do not detect nothing !!: sdm1402,1401,1502 and 1612/1712)
-Newest Liteon cd-rws: They have problems with some dvd-writers (sometimes) and some cd-writers (very few cases) because they are not capable of writing correctly some weak sectors of both safedisk revisions (although you write at lowest speed)
-Plextor Premium with last fw 1.05: They have problems like liteon cdrws, (using EWS in all cases because it is a very good one sheep burner only), but its problem is in some dvd-writers and may be in oldest toshiba dvd-roms, because toshiba sdm1402 and others have not given me problems of working.
For the first two cases you can use any cd-recording software capable of writing in raw mode like Clonecd, alcohol 120% or Blindwrite, using the profiles recommended by Alcoholer
For the last two cases I recommend to use a cd-recording software like Clonecd or Alcohol 120% or blindwrite to make the image at 8x speed using the right settings, and for writing use Blindwrite with autoplay (at 8x it is the optimal for liteon cdrw and plextor premium) to get a full working backup like on a typical LG or ASUS cd-rw.
Using autoplay of Blindwrite you can play games in some devices that liteon or plex premium can not get with its own capabilities.
It is important to use EWS with plex premium because some toshiba devices and LG devices detects extra weak sectors and the backups do not work although you use autoplay (in some cases I have seen)
The last option is not reading this post (for liteon owners) and use any cd-recording software capable of writing in raw mode, always thinking that some devices will not work. ( I am not talking about the typical toshiba, but some creative cd-roms or dvd-writers will not work)
For plex premium owners should use EWS in all cases; TLA #0002 here has the same problems. May be some plex premiums can make good SD2.90/3.1 backups, but I can not confirm that here.
Regards to all As you can see I have a good pack of devices to test all this I say.
