Hi,

Thanks JRL; I've actually been watching those for a while now.

But from my research about these drives, I found that they will not work on my Macintosh 512k without special software, which can only come from a floppy disk that has to be inserted into the internal drive. So those external 3.5's have to be used as the second floppy disk. So I must redouble my efforts in finding more info on that 400k internal drive so that I can know more about their mechanisms, in order to find what's sticking and fix it. It's so frustrating; no websites seem to have detailed info on how these drives work. :-/
