I have been using a Rainbow for 4 years now and I have a mix of double
and quad density disks. The quad disks I purchase before the formatter
was available for the Rainbow. The formatter came out for the Rainbow
in version 2.05 and later of MS-DOS. I now only purchase double sided
double density disks and have had no problems at all. The only disk
related problem for the Rainbow is that some manufacturers put an
extra thick reinforcing ring on the hub that can cause damage to the
RX50 drive in the Rainbow. Off hand, I can't think of what brands
do this, but a safe disk to use is Maxell. I have been able to get
them for a reasonable price and have never had one fail. I don't have
any connection with Maxell and you can buy whatever you like, just
a suggestion. How about it Rainbow users, any particular brands of
disks that cause the RX50 to fail?
