You are throwing something together. The bin.xxx files should only have a size of 240Kb and this files are simply copied onto DOS disks and then read under unix with mread. The dist.fs are written onto floppies with the rawrite or rawrite3 program and they have exactly the size of a full 1.2Mb floppy. Under DOS you see only 1213952 bytes, because DOS itself needs some space on the floppy to maintain it's own file system on it and to hold a potential boot block on it. -- ATS ( ats@first.gmd.de or ats@cs.tu-berlin.de ) Andreas Schulz GMD-FIRST 12489 Berlin-Adlershof Rudower Chaussee 5 Gebaeude 13.7 Tel: +49-30-6392-1856 Germany/Europe
