UNABLE TO LOAD PRODOS” – Why do I get this message when I try to boot a ProDOS diskette?
For a ProDOS disk to boot properly, you need a good copy of the PRODOS file. It can be copied from any bootable ProDOS diskette. Or, from IIgs System, copy the file named “P8” (in the SYSTEM/ folder) to your diskette and rename it to “PRODOS”. –Adam Myrow The error message means that enough of boot track (e.g. Track 0) was read to tell that the disk is formatted for ProDOS; but, for some reason, the system file named “PRODOS” is failing to load. Possibly, PRODOS is not present on the disk or the file is corrupted or there is a problem with the drive which prevents reading the file. If the disk boots okay from a different drive, this usually indicates that your original drive has dirty heads, may be poorly connected, has a problem with head alignment, or (5.25″) needs a speed adjustment. If the disk is a 5.25″ diskette created on a newer model 5.25″ (“40-track”) drive, it may be an HD (high-density) diskette. Standard Apple 5.25″ drives cannot reliably read HD diskettes– see the Diske
