[Coco] 2 x 3.5 Drives on CoCo

[Jason Law]

Ah I see, thanks for letting me know.

I found two links the other day helping Briza find some 720k disks and
posted them here:

I'll grab some of those myself to be sure :)

The HD disks are harder in the magnetic sense.  Taping over the hole puts
the
drive in a reduced write current mode.  So they fade, often before the
format
programs verify is done.  I would not use them for anything precious.  Its a
bit like pouring new cement, the question is not will it crack?, but when?

Someone posted a link that had dd 3.5 disks for sale yet, 5.25" too.  But
that was a couple of years ago, does anyone know if they are still in
business?
