Hallo Nick, I have had some thoughts about the 16 MB disk. > CBMDISK can read the main directory, I think this is a program written for the C64/128? Can I expect it to work on a PET/CBM? Don't think so. In 1999 a 16 MB disk could have worked out well but nowadays ???? The only reason why I support it is the way I programmed CBM-HD: I use parameters that describe a drive making 90% of the software independant of the drive. My 16 MB disk is just another type of drive..... But having an old 1 GB disk at my disposal, 16 MB is a laugh; I haven't enough devicenumbers available to cover all partitions!. That's why I started to implement two more drive types: DOS and CDOS. DOS uses the PC's original file structure as so. Unfortunately one is bounded to the 8.3 filenaming. I wish I could use the long filenames of W98 but haven't found out how to do it yet (or better: even haven't found the time to read all the articles I downloaded about this subject). CDOS is meant to circumvent that in a dirty way: I use a table that holds track of the C= name and the real name. Disadvantage: (C)DOS cannot handle commands like B-W, B-R and other track/sector related commands. Question for all: with the exception of diskeditors and copiers, for what can these commands be used? The reason I ask this is to find out if I still need to implement it in one or another way. I can think of one thing: to edit a file in the dirty way, like using DEBUG under DOS. But then I would end up with something like 'read sector XXX from file <name>'. But the I still haven't any idea how to put a 1 GB disk into an ancient track/sector mechanism. Comments are very welcome. -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| URL: Ruud.C64.org =====DISCLAIMER================================================================= De informatie in dit e-mailbericht is vertrouwelijk en uitsluitend bestemd voor de geadresseerde.
