Posts from The drive doesn't recognize Heroes of Might and Magic V Silver Edition. Auto-translated

I bought a licensed copy of HoMM5 Silver Edition, but my disc drive doesn't recognize it. The disc drive is a Toshiba DVD-ROM SD-R1202, and regular Heroes 5 runs fine. All other DVDs are read correctly. Why could this be happening? And is there a way to fix it?

The only problem at the moment is likely with the disc itself... But if it's a licensed copy, that shouldn't happen at all...
To be honest, I haven't seen this disc myself, but I suspect it's a dual-layer disc... meaning it's not 4.7 GB like a regular one, but 8 GB... Those who buy Igromania discs know this.
Your disc drive might not be able to read it.
Try checking the disc with your friends.

I also think that a dual-layer disc would be suitable – it could hold the regular Heroes 5, Hammers of Fate, and perhaps some bonus mission for the 10th anniversary of Nival Interactive. But its size isn't being displayed:( the drive says the disc is empty and even offers to write something to it. It's strange – the drive reads dual-layer discs perfectly, including those from Igromania. Thanks for the answer, I'll think about it.
