I will try what you suggest with disk image.
I have an s1000 and the latest eprom v4.4.
I was thinking it could be with the internal scsi cable because it has 3 connections and only 2 are used (one on the scsi board reversed and one on the raizin.
I doesn't put a jumper on T because in the manual it seems to be terminated as it is.
I used the power cable of the previous FD drive.
I bought 3 transend 1gb x80 thinking they'll work because of the rather slow speed and capacity.
You confirm a card can be writen on and still not be 100% usable?
I'll let you know.
Peace
