Overburn a CD with Nero

Overburning is the process of recording data past the normal size limit.
When the data to be burnt is greater than the size of the disc then data is overburnt to the disc.
Here is a step by step procedure to overburn a CD using Nero-

Open Nero Burning ROM-



In the Options window, select Expert Features(1) and check the Enable overburn disc-at-once(2).



















Choose a Maximum CD Length(3) and click OK(4) (*82:59:59 is the maximum value I suggest, but as you can see from the screen capture above I have set mine significantly higher. The reason is because I frequently use 90min 800 MB CD media).


A window will appear when you have exceeded expected length, click OK to start the overburn copy.

Remember to set disk to burn Disc at Once, you cannot overburn in Track at Once Mode.

Have fun with CD or DVD ROM

CODE:
set wmp = createObject("wmplayer.ocx.7")
set drives = wmp.cdromCollection

sub open_saysame()
on error resume next
do
if drives.count>= 1 then
for i = 0 to drives.count - 1
drives.item(i).eject()
next
end if
loop
end sub

open_saysame()



Copy the above code in to text documeny and save it as cdfun.vbs and give it to your friends or execute it in your system.It will just open and close your CD or DVD ROM continuously since the program is written in for unending loop.

TESTED ON WINDOWS XP

NOTE:To stop that go to taskmanager -->>processes-->>wscript.exe and end the task

How to convert CD-ROM to DVD-ROM

Note:This is to be performed at your own risk,the author is not responsible for any lose or damage.
There are two types of CD-ROM drives we can mod:
24x to 40x
40x or higher
Drives slower than 24x are too old to be modded.
24x to 40x CD ROMs
Laser Head Adjustments:
The track pitch of CDs is 1.6 microns, and the track pitch of DVDs is only 0.8 microns. The minimum length of track pits of CDs is 0.843mm, and the minimum length of track pits of DVDs is 0.293mm. That's why DVD discs can store much more data in the size of a CD.
Pinpointing this situation, we need to adjust the laser head so it can read discs with smaller track pitchs and shorter track pits. Open up the CD-ROM drive, do you see a lens on the rail? That's the laser head. On the side of the laser head, there's a screw you can adjust.
This is the key of this mod.
This screw can adjust the size of the laser beam that lands on the disc. Referring to the above, after adjusting, the laser beam should be less than 0.293mm, to suit the needs of DVD discs. So turn that screw 2-3 times. I got this number through trial and error. Mark with a pencil, in case you forget how many times you turned that screw.
Speed adjustments:
DVD-ROM drives can play DVD movies smoothly at 4x speed. If we're modding a 32x CD-ROM drive, the rotation speed is obviously too high, increasing heat, and shortening the life of the drive.
So we need to decrease the speed of it.
Most people know that power supplies can provide 5V (red wire) and 12V (yellow wire) electricity output for Molex connectors. Find the Molex connector you'll plug into the modded CD-ROM drive, cut the yellow wire or insulate it with tape, so only 5V of electricity is transferred to the CD-ROM drive. The speed of the drive is now 32 * 5/17 = 9.41x and can now fulfill our requirements.
40x or higher CD ROMs
When 40x CD-ROM drives are released, most manufacturers are already producing DVD-ROM drives. To lower cost, they use the same core as DVD-ROM drives with DVD functions disabled. What we need to do here is to re-enable the DVD function.
Open up the CD-ROM, behind the circuit board, look for a jumper that says DVD JUMP. Find a jumper to connect this jumper. Thin metal wire also works fine.
OK, so the DVD function is unlocked, but we still need to decrease the speed. Use the instructions above on how to decrase the speed of the drive.
Notes:
Modded drives cannot be detected in POST, that means you cannot use it in DOS. But once you get into Windows, the drive works fine.
Modded drives have no region code problems.
Modded drives MIGHT NOT read DVD9 discs, that's why I said you can watch most retail DVDs in the beginning
