Don't Put a Blank CD into a Dreamcast

If anyone wants to skip the details of how I made this discovery, go to 2:01 to see what happens when you put a Blank CD into a Dreamcast.
A few days ago, I discovered this cool but scary trick that you can do with the Dreamcast. The Dreamcast is capable of playing three formats: GD-ROM, Audio CD, and MIL-CD.
But it never occurred to me, until now, that what if I were to put a blank cd into a Dreamcast. The results, I must say, are quite catastrophic.

If anyone wants to skip the details of how I made this discovery, go to <a href="#" class="seekto" data-time="121">2:01</a> to see what happens when you put a Blank CD into a Dreamcast. Sorry that I forgot to put in what time should you skip in the video, but there is nothing that I can do because KZbin disabled annotations.

[@RockeyDAproductions]

im actually so pissed about the annotations though!!!

[@RockeyDAproductions]

also im doing the thing today at some point, gonna bench make disk load time then blank cd for 10min then benchmark load time agin.

[@RollerVisionStudios]

Yeah man, I understand your frustration. It upsets me that I can't put it in and because of that, people think that this video is clickbait.

[@forestreflection2066]

[@RollerVisionStudios]

Hmmm maybe... lol. :) Would you like to try and find out?

[@nukley]

actually, the disc would shatter way before that. and also the disk mechanism would get really screwed up. heck, it may even destroy the dreamcast due to the pressure.

[@PickyOldGamer]

My guess is that it spins higher and higher as it can't find data and then just is in the mode "looking......looking......looking" and then you open the console, it still is looking and is not "oh you want me to stop the disc ok". Neat find.

[@RollerVisionStudios]

I think you are spot on with your explanation. And thanks! :)

[@tweetiethebudgie3729]

Saiga GeneCast it sort of reminds me of how it feels to be a Windows Vista reading a bunch of computer desks that you don't even know plus I want to know about the history about Dreamcast and how It can't even read a blank CD

[@birb6539]

Picky Old Gamer i was just about to write a comment about it

[@Kyranio]

This also happens when the laser eye of the optical drive goes bad, with any disc. Funny thing is when you put in a normal dreamcast game, it will go to the audio player and play the warning for audio systems. ("This is a dreamcast disc, and will only be playable on a dreamcast system. Please remove the disc from the player now, or it might cause serious damage to it's speakers.")

[@Slot1Gamer]

because it can't read the table of contents correctly

[@LupinticDream]

I remember doing this as a kid. I flipped my sh!t at the sound, and instantly unplugged the thing.

[@zenithSSBM]

Nothing. I forgot to show that part in the video but after a while, the Dreamcast stops spinning the disc.

[@AmyraCarter]

It is a blank medium, of course the console is going to act in such a manner. It is trying to read for a data header that is there but is a bunch of 00 00 00 00 00 00 00 00 00 00 00 entries, so obviously, it is not going to read correctly and continue spinning. But, for the record, as 'scary' as this may sound, no, the Dreamcast isn't going to be damaged by this. The motor is capable of running like this without any sort of harm. Oh, and another thing, it will NOT continue to spin like that forever; after about a minute or so the console will stop trying to read the disc. You'll get your typical error screen afterwards. By the way, if you put in a CD-R that has music on it, the Dreamcast will behave in a similar manner, but as soon as it reads the header, it will stop. It will not run like that when playing audio from the disc unless the disc is in any way unreadable.

[@TheColinputer]

The reason for this. The dreamcast is trying to find the lead in on the blank. As it cant find it, it assume the disk is damaged and so spins it up faster to try to overcome scratches or other damage. The reason for it still spinning when you open the dreamcast is the breaking (which is just done by either shorting or using a resistor across the motor) is most likely only programed to do this for long enough to slow down a disk at the regular speed

[@qlucas5510]

TheColinputer That’s quite smart when you think about it!

[@koppo2.0]

U mean Braking?

[@Davidevgen]

just as i thought. it spins up to max speed looking for data or music. well sorry but that was a waste of time.

[@LatteWiiU]

Hi! i never knew you would comment on this video

[@raehik]

This is a lot less dangerous or strange than made out to be. The Dreamcast is simply reading a CD at the speed the GDROM drive expects. Likely it won't normally read at max rate due to the sound, but like Picky Old Gamer said, it can't find a start point for the data on the CD (since it's empty). CD/DVD drives usually make this sound when reading or writing at high speeds, due to the CD and drive vibrating at high read rates. Anyone here have a PS1 or PS2 slim? They also still have the disc spinning when you open the drive, but are a lot quieter (forgot if the PS1 was loud).

[@ThatVoxelBlock]

It's just read speed, it'll keep spinning up until it hits it's maximum speed to attempt to get a focus lock on the data tracks of the disc - which, of course, it will never find since the disc is blank.

[@RollerVisionStudios]

I think you are right on with that explanation. :) Do you think this action will damage the laser?

[@Schtiffles]

Saiga GeneCast the laser isn't the part you should be worried about. Running it at the maximum speed for an extended period of time will wear out the moving parts much quicker.

[@fakedeltatime]

Probably does that because it's trying to find where the data starts, since it doesn't find it, it just starts spinning faster in order to find it faster. Just my uneducated guess though.

[@DarkWiNKenzo]

fakeDeltatime well, thing is, many people think the same, which is true and considered fine, but, if you want to learn something in my expertises, here i come, so, first, lets take it to the basis, when you put a CD inside of a CD-ROM drive (in a PC for example) it would first try to find the table of content of "Lead in" which is in basic term is data that is given to the CD-Drive itself and adjust for exemple : it’s spindle speed, numbers of tracks, etc, and that is what that is not being found when we put a blank CD-R inside a Sega Dreamcast, you can now deduce why it kept speeding up : it had no way of determining at which speed the GDrom formatted disc is supposed to go at, hence why a blank media such as the one said in the example above keep speeding up, no table of content, and after a minute or two of trying to read the disc, the Sega gives up reading the unreadable pits and lands of the lasers reflection off of the disc.

[@SuperCasalXou]

Just let it spin. At some point it'll generate more energy with the disk motion than it's required to keep the DC on and you'll have unlimited energy for your house.

It might have something to with the fact that no cd is made perfectly flat, and not every hole is punched perfectly in the center. So that revving sound could be the vibration caused by an imbalanced distribution of weight and force.

[@jamesExiledLegends]

It's trying to find at what speed the CD was written. When you burn a CD at say 52x it has to spin faster to read the data than a 4x. So it's spinning up to the max RPM of the cd drive

[@Coaster42]

That wont do anything bad to your dreamcast, that is just what CD and DVD drives sound like at high speeds. My PC Blu-ray drive has a 48x speed mode for CDs, for example it uses this speed when first starting a program that is on the CD. When it does 48x mode it sounds like this. So for whatever reason the dreamcast runs the blank CD at a much higher speed than it would for anything else, possibly because it is trying to find the beginning if the data faster. This is also why the blank CD takes much longer than the GD to stop spinning, because it was spinning at a much faster speed to begin with.

[@macskasbogre133]

Why do you have so many dislikes?

People think that this is clickbait.

[@ZacabebOTG]

And yet they click on it themselves to see what it is about. 😂

[@blackdot105]

The dislikes? Why?

[@kmemz]

What is happening, is that as the console attempts to read the data on the disk, it is not finding any data, and erroring out, causing the PWM controller to set the motor to 100% while the laser seeks data, trying to find something to read. Normally, the firmware catches that the first few reads detected 0, and reports back to the OS as blank after spinning down. This step was possibly taken out, to clear a little more space to add the instructions that the games use, as Sega never expected, nor intended, for people to insert blanks. On the bright side, if your bearing ever degrades enough to start sounding rough or even sieze, you can clean, oil, and break the bearing, and put in a blank to make it spin, and spread the oil evenly.

[@lilorangefella]

[@AnimMouse]

Only Rich people hates pirated.

[@RollerVisionStudios]

Only people who really care about preserving Dreamcasts hates pirated games.

[@AnimMouse]

Well, for me, preserving a console means making them open to make hobbyist acknowledge them. For example, the Atari Jaguar is bad at marketing, but when Atari released their documents about the Jaguar, even the patent, that console is still living. Pirating Dreamcast games makes it cheaper, therefore more people buy it. Piracy helps more preserving it.

[@RollerVisionStudios]

I totally respect your opinion. If you want to use pirated games, go ahead. But what I meant about preserving Dreamcasts is that the pirated games actually damage the consoles laser. I highly recommend checking this video out by Adam Koralik because he explains in detail what exactly those burnt games are and why they are so harmful to Dreamcasts. Link: kzbin.info/www/bejne/d2enn4KtrseanpY

[@AnimMouse]

Oh, thanks for sharing the video, this is my first time to hear that Dreamcast is a failure for SEGA but because of piracy, Dreamcast is still living. GD-disc is not produced anymore. And about the burned disc, yes, it can damage the laser overtime, but from the forums, I read about gamers always playing with mil-cd, and their Dreamcast is still working fine.

[@RollerVisionStudios]

You're very welcome. Yes this is true, but I also heard a lot of stories of people breaking their Dreamcasts from playing burnt games. Those who haven't broken it yet, will in a matter of time.

[@KRAFTWERK2K6]

You should NOT put CD-Rs into your Dreamcast at ALL!! Unless you wanna ruin and kill the laser. Trust me, this is what killed most Dreamcasts back then when people pirated games and played burned copies from CD-R.

[@RollerVisionStudios]

Yeah, I totally agree with you. Unfortunately, there are a lot of people that don't believe it and play burned games on their Dreamcasts.

[@KRAFTWERK2K6]

Yeah… i learned that the hard way when i was intensively using some homebrew software and ports that I burned on some CD-Rs to play Doom and Quake on my Dreamcast and also experimented with some selfboot tools. But that was back in 2005 and i didn't know it better. Only found out years later while browsing through some Dreamcast reviews and forums. Oh well…

[@RollerVisionStudios]

Sorry to hear that man. Did you ever buy another Dreamcast?

[@KRAFTWERK2K6]

Yeah, i have 3 Dreamcasts now. My original one, a worn out used one that I got from a friend of mine, for spare parts and a few years ago i bought another second hand one including a few games. However that one too did not work quite well and I had to use parts from all 3 consoles to make one single working one. Sega really didn't care about production quality at all but at least the internals are very tidy and everything can be easily replaced.

[@RollerVisionStudios]

Man that kinda sucks that the parts on your Dreamcasts are not the most well built, because I have 2 of them and everything about them is fine. Yeah, the location of the internals is great and very well organized. Well, I am glad that you have one working Dreamcast. :)

[@CraftyMaelyss]

It's because it's trying really hard to find data, so when you put in a normal CD/disc there's data already there and it slows down to "read" it. When there's no data(like in a blank disc) it speeds up(like we would when we speed read or skim over pages) to try and find the content. When you open the console, it's still spinning because you opened it as it was still trying to find that data.

[@darkflux]

MIL-CDs are NOT all pirated discs (although the MIL-CD format did allow for things like Bleemcast to come into being). MIL-CDs are "Music Interactive Live CDs"...basically multimedia (video + audio) discs, that have music along with some visual display or interface. kind of like a music CD, but with either on-screen lyrics, music videos, or a light-show or something. perhaps band info or other extra stuff. they were only ever released in Japan, from what i've heard. there is a lovely Wikipedia article on them.

[@sadladcinn]

the run on the games tells it what it is and what its supposed to do if its not there it flips out

[@andrasfogarasi5014]

I think it's just looking for the beginning of the CD. Which is really hard, considering that the storage medium is unformatted.

[@flatfingertuning727]

Many CD readers have no way of directly sensing the speed of the motor, but instead adjust the speed of the motor so that data bytes are received from the disk at the proper speed. If no data are received, the machine will assume it's because the disk hasn't yet gotten up to speed, and will thus increase the speed of the disk less or until it decides that the disk simply isn't readable or it reaches its physical limits. I would not expect particular damage to the unit if the unit isn't run too fast for too long, but it would probably cause some excess wear.

[@kirito8720]

What’s happening is that since the disc is blank there is a trace amount of data on the disc but that data is way, way to small for the Dreamcast or any system to detect hence why the motor “red-lines” brings the disk up to full speed so if you put something on the disc as in BIOS/UFEI, ISO, or MP4. That data or information can be detected and read by the laser or reader. Basically a “blank” CD isn’t actually blank it’s got that tiny bit of data also known as system macro data (I think) responsable for read/write detect by the system. And that inner ring in game discs is actually the copyright protection data which doesn’t always work or function, so basically you can think of a game disc as well ROM Partition Memory, So you’ve got the Game Data in one sector/partition the Copyright Protection in the second sector/partition and the Startup in the final sector/partition.

[@Cubbie410]

Sooo the Dreamcast CAN play games, MIL-CD’s aka karaoke CDs, and music CD’s. if you did some research you would see that Sega never used the 1.4 gig discs heavily as the Dreamcast could NOT play dvd media. The games are on regular compact discs. Also fun fact.. some models can read burned/backup games. And of course if you put a blank cd into a Dreamcast it’s going to spin like that because it’s looking for data. It won’t harm the Dreamcast in any way

[@PhilXavierSierraJones]

Same happens with some CD players; they just don't know what to do (because it's blank) so it tries everything it can think of -- spinning it faster, moving lasers front and back -- and still get no results it thinks it should get.

[@SianaGearz]

I think it's trying to increase the motor current until it can find some pilot signal that it can synchronise the motor to. And it just keeps trying. Burned out spindle motors and motor drivers indeed happen, even on Dreamcast, even if rarely, these parts do not stand up to an arbitrary amount of abuse. The motor has limited braking torque so of course slowing down the disc takes longer as well once it's spinning that fast.

[@Nitro_GamePlay]

It may burn the spindle motor up, I guess this is due to the Dreamcast not being able to find data so it speeds the rotation up in the hopes of finding something and because there is no data it speeds up indefinitely until something inevitably break or burns out.

[@TPI_Trevor_Phillips_Industries]

Its doing this because it's actively trying to search for data on the disk so when it doesn't find it it keeps spinning faster because the Dream cast doesn't know what to do

[@crazyshit8]

What version is that though? The 0 and 1 versions can play burned CD games while the 2nd versions can't.

[@MrOmega-he4sf]

this is my opinion ,so the thing that maybe the reason the blank disc sounded spooky was that all the data was loaded from the disc as fast as possible because it never carried 1giga byte of data and it carried below far from 1 gig. this maybe possible and noticable from other consoles like a playstation.

[@aprilkolwey4779]

Normally, in a CD player or CD drive, spindle speed is maintained by essentially watching the speed of the data coming in from the disc and adjusting the motor power to maintain it at the correct rate. However, for a blank CD-R or CD-RW, there is no data, so the motor power is increased to the maximum to attempt to speed the disc up. Finding the correct speed on a blank disc is more complicated (there's a slight wobble at a certain frequency, and it maintains this), and while a CD-R or CD-RW drive can do this the firmware in a CD-ROM drive or audio CD player is completely clueless. On a sort of side note, it sounded like the disc was going, at most, about 5000 RPM. That's about 24x speed, or not even half as fast as the fastest CD-ROM drives.

What happens if you keep the blank CD IN the Dreamcast? Does it spin forever, or eventually kill the system?

[@RollerVisionStudios]

Not sure as I don't want to try that myself. But if you want to do it, be my guest. :)

[@Stoney_Eagle]

It sounds like it even has more power to go much faster. The cd will explode into a thousand pieces if it reaches its breaking point. This makes much sense since the cd reader is not able to find the starting point of data and the reading speed is dynamic and always starts out very slow and speeds up until it can properly read the data. But if there is no data this is what happens. Either the cd explodes or the motor burns out. Check out the slomo guys they have a video about breaking a cd with rotation speed

[@cpu64]

I don't see what you're freaking out about... It simply kicked into full drive speed in order to try and read the entire disc before timing out... PC CD-ROM (72x) drives were much faster than that Dreamcast during normal data read.

[@Supernova1300]

i thought that, the drive goes up with the rpm. This also could happen with audio cd players,sometimes if an cd player could not read an self burned audio cd or mp3 cd.

[@EmikaSandra]

Imagine leaving the blank CD in there for an extended period of time. You'd probably burn both the CD and the system with the blender noises that come from it.

[@mattw8910]

Ik this is years old but for those who are not aware that noise is the Dreamcast trying to find the data on the CD. Not anything dangerous to the console or disk.

[@PeterDCOHanlon]

I had an old CD player that would do this same thing, and if left to go through the whole reading process, it would leave a MASSIVE, DEEP scratch on the CD in a circle shape.

When you trying to perform the Jedi mind trick on your Sega Dreamcast *Pops in disc, waves hand , This is Crazy Taxi*

[@jsc315]

If it's a properly burned Dreamcast game it will use the motor that reads the disc a lot more and can potentially harm the Dreamcast but other than that it will play them fine other then the music and video will be compressed. The reason it's so loud because it unable to read any data and continues to spin trying to find if anything is on the disc.

[@Lachlant1984]

I expect if you do it too often or for too long, you may very well damage the console, but I think just doing it once and for a short period of time won't do too much harm. If anything, you'll probably wear the motor out. BTW, I though I read that later Sega Dreamcast console were designed such that they couldn't play CD-R media in an effort to stop game piracy.

[@RandomTRandomReal]

But what happens if you put ham in??

[@growlie2676]

This happens to me sometimes when I burn a cd and sticks it in my cd player. I guess, apparently my disc wasn't burned property so my cd player wouldn't play it. And yes, the disc spins really fast, from what I've noticed myself, why is that?

[@allrock1238]

The optical drives software is attempting to archive optical focus lock onto the media, then achieve proper sync with the disk speed in order to get a valid data stream and read the disk ID and table of contents from the disk, the laser detector does detect reflected signal coming back so it thinks at least an optical "disk is present" "but" there are no written servo sync references on the blank disk so it sends a command to the motor servo controller to increase the disk motor speed because it cant find a valid signal hence the disk spinning up to ridiculous rpm's , Most optical drives would simply "time out" with invalid format disk not recognized"

[@BensonManifests]

i believe the noise is more to do with the sound of the motor working harder to spin a (relatively speaking) heavier disc

[@Eggointheghetto]

But i burned my sa2 and it works fine im confused is it because of data? Don’t scold me plz i only did it because if mine breaks i have a backup

[@animemanXLK]

My dream was incredibly tempermental towards the end of having it. the controller broke at the port so I managed to cobble it back together with blu tac and sitting on a block of lego and the disc drive refused to run to when you put a game in it. instead I had to open the disc lid and weight it down with a plastic and metal model tank so it would load the games

[@regnij01]

what happens at the screen?

[@glitchgamemaster500]

Funny thing i put in a hack program on a blank cd for the sega dreamcast to get DLCs that we cant anymore for the sega dreamcast games and it never made that loud sound on my brothers sega dreamcast when he used to own one

[@zdenenkschijbers187]

I like your humor dude, keep it up!

[@RollerVisionStudios]

Thanks man. I will. :)

[@Lachlant1984]

I did this to my Sony stereo system back in 2000 and it too spun the CD at high speed, I think this is common, and doesn't just happen on the dreamcast, I think most CD players will do something like this if you insert a blank CD-R or CD-RW disc.

[@darkfoxfurre]

That's the sound of the motor seeking to find data on the disc.

[@PastaPistol]

This is actually a really interesting find.
