How do I open a modified or slightly damaged DOS 3.3 disk?
The disk format auto-detection algorithms rely on finding the disk catalog track. If it’s very short, or partially damaged, CiderPress won’t recognize the disk. In some circumstances you can specify the format manually: • In Edit->Preferences->Disk Images, select “Confirm disk image format”. • Open the disk image with File->Open. • When the disk image format dialog appears, select “DOS sector ordering” and “DOS 3.3”. (If that doesn’t work, try “ProDOS sector ordering”.) This can also be used to select which half of a hybrid DOS/ProDOS image to use.
