the cd from " ozark henry " is protected with , i think , the key2audio protection ( sony ). in fact , it contains 2 cd ' s : a protected cd ( indicated on the label ) and a bonus cd ( not protected ) . when i ' ve putted the protected cd in one of my cd roms , it was not possible to read the cd or play the cd , in fact it keeps searching and searching for the cd . i ' ve tested it with my plexwriter 24/10/40 ( ide ) , then with my plexwriter 12/4/32s ( scsi ) , then with ultraplex 32ts cdrom , and finally with my pioneer dvd rom uo3s ( scsi ) , no way ,
finally , i left the cd in one of my cdroms and shut of my computer and restarted it , once the operating system was started up , the cd was recognized by explorer or nero or clone cd , in fact i was able to make a copy of it with clone cd and even with nero ,

to be sure , i ' ve tested this a few times , always the same result ,
does anybody know the the reason why this happens ?

thankx ,

I think that's the protection at play - it detects an AT device rather than a commercial CD Player. Rebooting as you described may just be the way around the prot at the moment!

Comments anyone?

This was a crosspost (and I don't like crossposts ).
Since the other topic had 1 reply already, I will quote that here and delete the other post.

What is an 'AT device'?

Very strange story... According to FatChucks ( http://www.fatchucks.com/corruptcds/index.html ) this cd has indeed Key2Audio. Like I have written in these fora before... my experience with Key2Audio (Shakira - Laundry service) is that it is one of the weakest protections around... (compared to CDS) did not need the tricks described below... my Plextor PX-40Ts just read it... in all my available programs (EAC, CloneCD, Nero, Feurio), only Explorer would not show me the content of the cd.

"The protection at play - it detects an AT device..." Sounds like an audio copy protection is some kind of program which can detects stuff... this is not the case! The trick behind audio copy protections is to confuse the cdrom-player with fake/illegal entries in TOC, subchannels, sessions, etc. A normal audio cd-player can't be bothered by these things... it just reads the first session it encounters.

Another thing: for some (all?) data-protections you need to make sure that the OS doesn't access the cd first before CloneCD can because otherwise the OS doesn't give exclusive access and the cd might be inaccessible, even for CloneCD! This is in complete contradiction with the method described above... Can't imagine this procedure may differ for protected audio cd's.

Thank you for your usual excellent explanation

ATAPIMore here & here

Remember how we had to plug our 2x CD-ROM into the sound card...? ATAPI made IDE connection possible

thankx for the exellent replys , the only fact that i forgot to tell is that i tested it with windows 98 , windows 2000 ,
with windows xp the above method didn ' t work ,
bye ,
