Should I read at lower speeds?

Machina · #1 01-08-2003, 17:24

I have Lite-On 52x/24x/52x CD-RW with latest firmware.
So far I tried to burn (backup) only one game with it - BF1942 and I used Alcohol 120%. I read that Bypass EFM error has to be unchecked (or use SafeDisk 1 settings, but the game is SafeDisk 2 protected).

Well, I read at speed of 52x and burnt at 52x
I could NOT makr a perfect backup, I tried 3 times, and it does not detect the CD as the original.

Should I read or burn at lower speeds?
Any other ideas why I can't make 1:1 copies?

Note: I got latest drivers for my IDE controller, etc.

why not try answering your question yourself and actually try reading at a lower speed and seeing what happens.. trial and error

It takes too long, my CD-RW won't work with Alcohol 120% unless its in PIO mode which is SLOW even at 52x...

The only thing I can also try is set the PRECISION thing to HIGH from NORMAL.

Read with 4x speed -> use Safedisc 2 profile.
Write at 4x or 8x with the SafeDisc 2 profile to.Should work.

40 minutes per CD

If you need to do it very fast than try to burn at 16x-24x but when making an image use a low speed reading to create a good image

My friend burned a CD at 52x and it was unreable (LG)

Hmms, should I use the HIGH precision thing too?

Mateusz · #8 03-08-2003, 13:37

No : High Precision is only for CDs that are protected with physical meansurment protection like CD-COPS , StarForce.You have a simple SD 2

Hmm...Vluka's guide says MAX SPEED everywhere....

Machina ,

I do not know this game - 'BF1942'.

However I do own an LTR 52246S myself and have never made non-working dumps despite constantly setting clonecd/blindwrite reading speed to Max, whether I wuz dealing with Safedisk 2.xx, Securom 4.8x, or whatever...

Have-you got ClonyXXL latest version? If so, what protection exactly does it indicate ?

If it's safedisk 2.8 or later, then forget about alcohol 120%, or even clonecd - indeed the limitation comes from the software, not the writer, for your Litey does offer full pregap-reading support, but neither alcohol nor clonecd do bother to read the pregap - they just generate it, leaving the protection unshaken

. Discjuggler is known to be able to read all the lead-in data (which comprises pregap), as long as the reader/writer allows it, which is your case. Otherwise, U could give Blindwrite 4.2 or later a try...

I was using Alcohol 120%, and the game is SafeDisk 2.8 I think (I know its SafeDisk 2 for sure).
I read about how to burn it, followed all the intructions, but the copy does not work...

Hey slow down man, U replied too fast I was still editing my previous post

. Do read it again...

Machina · #13 04-08-2003, 07:33

I've been using BlindWrite before Alcohol 120% and I do not remember being able to edit many settings there (does it figure out what protection is used by itself?) , and it says that Alcohol 120% has a higher precision reading or something...
I did like BlindWrite, but from what I heard, it does not make 1:1 copies, it uses other ways to make WORKABLE copies...

Maybe I should try it again...
I made working copies of Morrowind with my Plextor 16x CD-RW and BlindWrite...

When VSO released their 4.2 blindwrite version, at that time they claimed that theirs was the only software capable of making 1:1 copies of safedisk 2.8 without any workaround needed, provided the writer wuz up to it. I'd advise U give it a try (! remember 2 disable weak sector amplification !) - with safedisk 2.x, in theory there is no need to Xtract subchannel data. But if you do, disregard Clonyxxl advice, for the 52246S is known to be far better at extracting subchannel data at high speed

(yes seems unbelievable to me too, but I copied UT2003 using Blindwrite at max read speed, successfully), so set read speed to max.

In theory, the 52246S (and even some previous LTRs) is 'ideal' for safedisk 2.xx schemes, even 2.8 & 2.9

However I've had contradictory reports concerning safedisk 2.8

Indeed on one hand I've heard that safedisk 2.8+ was specifically aimed at 'targetting the LTR 52246S's 6S chipset' - the @%*$¤§#! bastards

(anyways future Liteys such as 52327S will have new chipsets hehe...)

On the other hand I've had multiple reports of successful 1:1 safedisk 2.8 or even 2.9 backups created with this same writer, without any emulation needed...

Besides, to me having a protection scheme target a specific chipset simply doesn't make sense, since software can only interact directly with a device's firmware, not its chipset.

what is your firmware revision? (mine is '6SOF' - the latest

)

Machina · #15 04-08-2003, 11:39

Yes, thats my firmware version.
Well, I hate having more than one utility to burn CDs. I use NERO for all the normal stuff, and now use Alcohol 120% for backups.
I NEED Alcohol 120%, without it, I cannot install Gothic 2 backup - I use Alcohol's emulation for it to install properly...
