A doubt about Zaxon DDI-1 in a 464

[angelcaio]

Hello. this is rather a small doubt than an urgency
In 2014 I bought a DDI-1 from Zaxon, I connected two drives to it: a Sony 3.5" with the mod for the real Ready signal, configured as DS0 and a Mithumi 5.25" drive configured with microswitches with Ready signal and as DS1
Both are connected with a flat cable without twist to the DDI-1
Both work fine but there is a strange behavior on drive B:
When I read, I load a program from B: or I make a directory, all Ok, but when I try to write to B. I need there to be an unprotected disk inside drive A:
This is normal? Has it happened to someone else?
