Cracks or grooves? Big difference there.
Radial cracks. I got grooves once with the HPS pads, then switched to DTC-60 and never had that problem again.
I hated my DTC when I had them. They need TONS of lube on the shims, a very thorough bed in process, and new rotors to try to prevent squealing, but they still end up making some noise. They howled when coming down from higher speeds too. I switched to Porterfield (Pagid) on that car and they were silent in comparison. Far less dusty too, which was nice because my hands didn't get as dirty when swapping wheels.
Haha, each to their own, i loved those things in spite of the noise and dust. Now i have three sets of HB543G.760 and two of HB544S.628 that won't fit on the "new" car... so many things to fix...
