Vice City Play disc - are there any read errors?

I’m trying to make an image of the GTA: Vice City Play disc using Alcohol, and I get a disc read error at 336741. I tried reading several different times at several different speeds, and still get this error. Does anyone else get this error when reading this disc? Is this normal?

This is typical of securom 4.x new.

A Mode 2 sector in the Mode 1 track (the disc is just one big track) will trip up a casual read. If it’s corrected, it will fail authentication.

Thanks for the info, everyone. It is reassuring to know this is normal.
