Ok, just to make a few points crystal clear here..
*Codys & my disks didn't 'go' bad..they were created badly.
*Tosec & dats are for cataloguing only and bear no influence on whether the images they catalog are for emulation or the real thing, it also brings new images to the 'real' users as no such system exists on Amiga.
*To image a disk 'readdisk dfx: image.name'
*To write an image to disk 'writedisk image.name dfx:'
As previously stated, i use ADF instead of DMS on my real Amiga's.. nothing to do with emulation.
Its your perogative to use a potentially faulty product, and if you have problems of corrupt disks and don't do what CodeT does with comparing disks, its no fault but your own.
