The program FDFORMAT ver 1.8 has options for sector sliding, but doesn't have the optimizing routine mentioned for diskrw. FDFORMAT can also format diskettes to non-standard formats. I use it to format all my old 360K diskettes to 820K for use on a 1.2MB drive. You need to included FDREAD to load as about a 160 byte TSR to be able to read non-standard formatted diskettes. You can find it at Simtel as PD:<MSDOS.DSKUTL>FDFORM18.ZIP Personally, I've tried different sector sliding values and have found none that works better than the standard no-offset. -- ======== Boyd Johnson nosc!spectra.com!johnson San Diego, Ca. ========
