Is there "Master Directory Blocks" in LBA 1? Please check it by IsoBuster. Master Directory Blocks have "42 44" in the 1st and 2nd byte.

And I updated bug_report.md of issues. Please see it and tell me the Disc title, Disc ringcode, Amazon and eBay URL if possible.

This is a vintage Macintosh magazine cover disc from 1995. I suppose it's not very common, and will be a new dump for redump. If I see on for sale in future I'll let you know!

I'm willing to loan it to you if required? Alternatively I can provide a RAW dump from ISO Buster?

PS: I also have Vol.3 and Vol.6 and they dump fine. I will have Vol.5 soon and will check.
