While performing some recent overreading tests,
I accidentally discovered sectors in leadout can be
accessed until its end when using rewritable media
and a capable drive, so the idea of measuring the
leadout written by all burning software came to
my mind. You can do it with a Plexie and a CD-RW.
You will need also an hexadecimal editor (WinHex)
and Truong's CDReader, If your CD-RW has been
used before you must fully format it, if it's new
you can proceed with this next step: download
and burn it with Golden Hawk CDRWin (other
softwares wrongly complain about wave size
and pretend they overburn).
Next step is to pick the shortest CD in your collection
and burn a copy after a quick format to your CD-RW.
Now comes the interesting part, launch Truong's tool,
press CD To Image button, select your drive and press
From TOC to obtain the last program area sector number.
Copy mentioned LBA to clipboard, close and press View
Sectors, you paste clipboard content into address field...
press Read sector button and you'll get into last program
area sector, buttons < and > are used to navigate disc.
You should be in leadout's first sector by pressing > once,
you can tell by the Q subcode TNO, it has to be AA, see:
if your burning software follows the standard the leadout
will end after 90 s (6750 sectors), If you used CloneCD it
will end after 60 s (4500 sectors) and if it's Nero's short
leadout will do 5 s (375 sectors). You can tell leadout's end
when Truong's CDReader's main channel show this pattern:
