I have not found this to be the case in practice.  I believe Andy is
correct that diskettes with one bad side are sold as single-sided
diskettes, but experience suggests that the main difference between the
single and double-sided varieties is the label and the price.  (This is
probably why the price difference is so low now.)

At one time manufacturers claimed that single-sided disk jackets lacked
some sort of treatment or lubricant on one side.  I've ripped apart
several of the plastic jackets of different brands and I have never seen
a difference.  I have only rarely had a problem using single sided
diskettes in double sided drives.  However, the cost difference is now
so low that I go ahead and get double-sided ones.
