I notice that none of these cards have a master/slave jumper, which means they are probably cable select only. This in turn means that they might work in an Amiga, but only with the one card attached to the IDE cable.
I ordered one, but for my Amithlon set up, though I hope there is a jumper, I'm not sure how it would work without one, unless it is just designed to be master and nothing else, in which case the Amiga should in theory be able to use it too. In fact I can almost swear I've seen users using these on their Amigas already.
As for me, I am going to format it under MorphOS or Workbench, and see if I can get Amithlon to read it. If I can, then I don't have to bother putting it on a network, removing the drive to write to it under AROS, or wasting money burning CD's for each and every little file I forget.
