Hi Roy,

that is some valuable info.
Indeed I didn’t take a look inside those cartridges yet, but that helps should I run out of spare drives at one point.
I got another almost fully loaded H12 that was completely unused and is basically mint condition along with the H12 that was used together with the A500.
So I just swapped defective parts, resettet everything and did a fresh setup on the machine.
Works like a charm and was also pretty straight forward.

I wish SANs were as easy to use these thays :D

If this is what has failed, and it usually is that rather than anything in the cartridge itself, getting them going again should be quite cheap and easy.
