Ritek D01 vs MKM001

What could possibly cause a drive (NEC 3550) to be able to read a Ritek piece of crap and not be able to read an MKM001? (all twenty by the way)
Thanks for any suggestions.

@Curleyg - you already asked about this here in the NEC/Optiarc forum, albeit with more detail than you’ve given here.

Please don’t crosspost…it’s against forum rules and makes more work for staff and members.

I’m closing this one, so if anyone can help Curleyg, please post to that thread. Thanks. :slight_smile:
