Re: HD 5.25 format?

Here we go again!

Despite the widespread library of information that Double Density and 
High Density 3.5" disks have SIGNIFICANT differences in magnetic 
properties (higher coercitivity of the HD media), people persist in 
wishful thinking.

There are only TWO kinds of people who use HD disks in DD drives:
Those who have had problems, and
Those wo WILL have problems.

Which will YOU be?
