I read an interesting article in PC Magazine that I wanted to share with you. I found this in the April 13,1993 issue. On page 122 it states...Don't throw out Dos 5 just yet! Although the list of programs, drivers, and utilities that will ship with DOS 6 wasn't finalized at presstime, it appeared that DOS 5's Mirror and Recover commands would be dropped. This would be unfortunate; Running Mirror with a /PARTN switch is a handy way to back up the partition tables on your hard disk, and Recover (though a potentially dangerous command) can salvage files that have developed bad sectors. Before you throw out DOS 5 it's probably a good idea to make copies of MIRROR.COM and RECOVER.EXE. Make a copy of DOS 5's UNFORMAT utility as well, because you'll need it's /PARTN switch to restore partition tables backed up with MIRROR. Since DOS 6 contains it's own UNFORMAT command (without the /PARTN switch) give the old one a new name, such as UNMIRROR.COM.
