How did this crack happen?

I put the CD in the drive after checking it for scratches (maybe not hard enough?). It started ripping the first few songs well, but it stopped at track 6 which is when I took the CD out and saw a crack half way along the radius. Otherwise it looks okay (the print is fine and there are no other deep scratches). The drive can't even detect the audio CD now. Maybe there was a chip in the inside circle that weakened it?

Is this unheard of (a disc becoming unreadable and breaking when ripping?)

I have had a disc explode in an ASUS drive a long time ago. The 'explosion' was powerful enough to blow away the front panel with 'ASUS' and the model number painted on it!!
I hope that this particular CD is replaceable. I can only recommend the limiting of ripping speeds during all of your future CD ripping endeavours.

I have never witnessed this, ever. I can only speculate that it was the fault of the CD drive itself, not EAC.

Oh, my drive exploded even before I discovered EAC. I kind of remember that I was using MusicMatch Jukebox to rip my CDs those days...

It isn't EAC, just the CD or the drive or a combination of both.

Was it a DualDisc (one side CD, other side DVD)? Similar happened to such a DualDisc on my Samsung drive, probably because a DD is a little bit thicker than a regular CD/DVD.
However, haven't seen something like this with a normal CD...

@rohangc, I've heard about that happening... The drive is near my head! The CD is replaceable, it wasn't a very good album anyway.
@Zarggg, I know EAC isn't to blame, but it the thorough error checking and long extractions would put more stress on the disc/drive.
@exec, It wasn't a DualDisc. I don't know if I can check if it's a cheaply built disc?
@greynol, Not all of it was generated with EAC, I shortened the information to show what time the files were created (Tracks 1,2,3 took roughly 1 minute each but then tracks 4,5 took 10 minutes to copy okay and then the rest of the CD failed).

I believe this has merit, though I don't think the stress is so much based on how long the disc is spinning, rather the forces exerted to slow it down and speed it up, which seems to happen more often during secure ripping with re-reads than simply with a single continuous uninterrupted pass of burst reading.

If one wishes to attach blame, it is to the initial cracks that were present before one of them spread.

I had this problem once before too - the CD shattered into dozens of fragments. I thought I'd try-out iTunes and see how fast it could rip a CD; apparently, it was too fast!

A friend of mine had the exact same problem as yours, with the same drive, so i think the first thing to blame is the drive itself...

I've had 2 cds crack like that and one EXPLODE into 5/6 parts (destroyed the drive as well). It's not EAC (or any other particular ripper) it's the disc/drive combo...
