so the new DiskDoctor with OS3.1.4 only 'examines' hard drives so what to use then on drives larger than 4GB's nowadays to try to 'repair' issues ?
SYS:System/Format - there are no tools around to "repair" a broken "modern" FFS.
DiskDoctor is not a good name, it doesn't by any means "doctor" disks, a more describing name would be "FFSDump", as that is all it does - dump the content of a broken FastFileSystem.
I wish there was ways to prevent the built in validator from starting, as it often crash for various reasons (low memory situations etc), and just allow _manual_ optimistic read-only mounting of FFS also when running AmigaOS (and not just when running NetBSD or Linux...)
