Re: damn checksum error on FFS partition!

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...)

ouch  :o so we have nice large new FFS partitions with new roms and OS3.1.4 + but no way to fix or try to repair common issues on them unless we keep them beneath the old 4GB limit :o :-\ :'(
And also "no long file names".

But seriously - how often do you really need to repair filesystem on Amiga? I know that it doesn't really happen so often with my systems.

One thing I have been looking for, is a proper "shutdown" tool, that makes sure all local drives are dismounted ("BUSY") before popping up a requester with a "Reboot" button, telling me that it is now ok to power off the system.

HDToolBox (RDB) and Early-startup could allow setting partitions read-only, or "non-validate".

Always use frequent backups and distribute them for safety.
(even when it means breaking the software license that the operating system is distributed with - sigh!)

Yes, sounds like a good plan :)
