I have finally got an Osborne 1 with SSDD drives to add to my others that
have SSSD drives. Now I have finally been able to boot an O1 with a SSDD
boot image courtesy of Don Maslin.
I have been unable to make SSSD disks on a PC. Is there any way I can now
make one with the SSDD Osborne?
Thanks,
Hans

Sure, the COPY program offers disk formatting in either SD or DD. Take
your choice.

Hi Hans
The biggest trouble with making SSSD on a PC is that
you should use a SD drive. If you have a DD drive, the
track width is smaller ( assuming that we are talking
about 5-1/4 inch drives). In an emergency, one can place
the disk on a flat iron metal surface, ( I use the refrigerator )
then a few pieces of paper and drag a strong magnet over
the entire disk. You then reformat the disk with whatever density
you like and it will work on SD drives. You can not use
preformated disk because the DD drive doesn't completely
erase the original track. It is still best to us a SD drive.

No, SD and DD 40-track drives use the same track width.
It's only 80-track drives (which category includes but
is not limited to HD drives such as the IBM 1.2M format)
that use narrower heads.

Don't you mean a 360k drive as opposed to a 1.2mb drive? Or a DD drive
as opposed to a HD drive? There are no SD drives that I am aware of.
