PS2 makes loud grinding noise when playing some blue disc games

[razorbeamz]

Whenever it loads on some blue disc (CD based) games, especially Half-Life and Tetris Worlds (but weirdly not Tekken Tag Tournament) my PS2 makes a very loud grinding noise. It doesn't scratch the discs and it doesn't affect the loading, but the noise is unsettling. Anyone know what's causing this?

The ''grinding'' sound you are hearing it the disc losing traction and slipping when the spindle motor tries to spin it up. I don't know exactly why this happens with the blue CD format PS2 discs, maybe they're thinner than the latter DVD format PS2 games. There's nothing really you can do to permanently fix it on the PS2's side. 

Some people put tape around the inner diameter of the disc to artificially thicken the disc to improve traction. However I wouldn't use anything but electrical tape to do this as it shouldn't stick on the disc hard enough to damage the label when trying to remove it.

Well it can't be just the discs, because my brother's PS2 plays them just fine.

Its the drive. I had a PS2 running blue discs that did the same thing. I rarely play my blue disc games anymore.

If his PS2 is a fat it will eventually have the problem. There's a rubbery coating on the spindle motor that wears down overtime and it causes a loss of the grip on the disc. On the slims the disc snap tightly into place onto the spindle motor so they don't have this problem.

What's blue disc?

What's blue disc?

Some PS2 games are blue instead of silver under the disc. I believe the blue ones are CDs while the silver ones are DVDs.

Are the blue ones launch titles?

Not all of the blue ones are launch titles. Some of them are just titles that used less data and didn't need to be on a DVD.
