Does anyone here have any experience or technical knowledge regarding the Korg D1600 CD backup format? This is the message I sent to Korg Support...

I am trying to restore my D1600 from CD backups (there are 24). The restore process starts fine but gives me an 'Illegal Disk' error when I get to disk 4 (at which point the restore is 43% done). Assuming there is a bad CD in a set of backup CD's what is the procedure to bypass the bad disk and go on to the rest?

Thanks for any ideas you might have!
