In order to format an RX-50 disk you need to do a 96 TPI 10 sector
single-sided format. I have done this on an AT 1.2 meg drive using a
couple of different utilities. Jformat, UNIFORM and probably XenoCopy
are commercial packages that I know of that can do this. I have used
the first two. DiskMechanic and many other flexible disk copying
programs can also do it, the question is whether they can be used to
create a format rather than just copy it (most people do not have two
1.2 meg drives and most copy programs require two). There was a
public domain driver that double stepped the floppy drive for mess
dos, I think it showed up comp.sys.ibm.pc a while back. It might be
possible to add a 10 sector hack to this program.
Anyway, using UNIFORM and an MS-DOS disk, I reformatted into 96 tpi 10
sector single-sided on my AT and then inited it on a microVax as
files-11 media. I got a whopping 400 blocks out of it, the disk came
up clean. The uVax one-sided drives are a real minus. Thrilled with
my accomplishment, I decided that the medium was so slow in creating,
so small in capacity and so redundant in function that I would not
bother to do it again.
Have fun.
