Hi JLew,
David already asked the relevant questions, but here's another approach to this:
I'm not clear if the "disc" you're talking about, is the hard drive inside the D8B, or if you mean that the floppy disc to re-install the OS doesn't work anymore.
Here's where you can download images of the installation floppy disks (how you extract those to the floppy drive, is critical... you can't just copy it over, but have to use the Windows application, to extract the images directly to the floppy discs. The Mac images are for MacOS 9 and older... so, hopelessly outdated, unless you have an old Apple G4 or older, that still has a floppy drive in it).
https://www.sonido-7.com/d8b/index.html#Post6If you mean, that the D8B itself doesn't boot anymore, and you were looking for a "copy" of the harddrive... that's not this simple. Here's the procedure how you can "copy" a D8B harddrive, in a way so it's actually bootable, afterwards (if you were to just copy the files over from another D8B harddrive, it wouldn't be able to boot up... that is, unless the drive inside the problematic D8B, was formatted using the D8B installation floppy discs and has a different kind of "data corruption" - then you could just copy the files from a different D8B, to your D8B... how the drive is formatted, is important, though. Formatting from Windows or Mac, won't work, and copying the files from another D8B, to a Windows/Mac formatted D8B drive (even if formatted in FAT or FAT32) won't allow the desk to boot, afterwards... the way the D8B formatting program writes the boot sector of the harddrive, is critical):
https://www.sonido-7.com/d8b/files/user ... acrium.pdfYou could of course use a different application to clone the D8B harddrive, instead of Macrium, if you're savvy with that (an old copy of Norton Ghost works well for that, for me). What's important, is that the whole thing, including the boot sector and file system get copied... not just the active volume on the harddrive.
After installation - regardless of if you do this via the floppy discs, or by cloning... you will get a prompt to authorize the Mackie OS and the plug-ins you own. For that, you can either enter the original serials that came with those plug-in purchases... or, if you don't have that, or want to upgrade to Mackie OS 5.1 (the latest version), you can read through the first post on this page:
https://www.d8bforum.com/phpBB3/viewtop ... &start=150Basically, download the attached file, and then replace the file "MackieOS.exe" on the D8B harddrive (after a fresh, successful installation of Mackie OS 5.1), with the version in the zip file from that post. Then reboot, and the Mackie OS should come up as authorized, including all the available plug-ins.
If you get stuck somewhere, please describe what steps you took, what the problem is, and what EXACT error message you get (if any).
Best of luck!
