But when going through all the trouble of changing to a new disk image format (converting to FDI) its still pretty limited. I think diskimages should only contain a relevant data for minimum requirements and everything else optional (how many (zipped) dsks are around that contains junk filled 'empty' sectors, it should only be included optionally) . I don't know about gunzip but some compression algorithm that allowes sam to decompress on the fly and has some sort of crc to detect bad images are highly recommended. > works in my existing MakeSDF utility (as seen by only a couple of you): >Snip< Maybe something to add for my B-Link Project the extra disk/sector info could be used to easely detect bad sectors in images. > > a.
