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. -- D Gary Grady Duke U Comp Center, Durham, NC 27706 (919) 684-3695 USENET: {seismo,decvax,ihnp4,akgua,etc.}!mcnc!ecsvax!dgary
