DOS differs between the two. My guess is that 1541 shows static data stored in the directory sector, while the other one uses actual sector's metadata. >> >> I don't get what you mean. > > I would have to check exactly what the differences are but there are other people who I bet have them in their heads ;-) while I vaguely recall that the DOS 2.6 in 1541 is not the same as DOS 2.x in other drives. This means there may be nuance differences, and if you write a D64 (from a 1541 disk?) to another drive using DOS 2.x things like you describe may show. Once you re-VALIDATE, the drive updates the metadata to what it expects, rather than what 1541 would expect. I would expect that cbmlink just writes sectors, starting from 1,0 and ending to 35,16. I don't think it even knows about directory, BAM and so on. On a 1541, even disk id (the two characters you give at format time) gets changed from the .d64 image. On a 3040 they don't. I don't know how much "metadata" is present on a .d64 image though. F Message was sent through the cbm-hackers mailing listReceived on 2018-03-05 23:04:29
