Cant get my old Amiga 1200 Disks to read on Amiga 500

I think the easyest way to do the OFS/FFS convertion is ReOrg.

You will find it on aminet, there is also a patch.

This is a part of readme:

"In addition to optimizing a disk, ReOrg can also convert
the filesystem of a disk during the optimization, e.g. from OFS to DC-FFS"

I hope this help, let me know.

Some time ago I do something like that, ReOrg works "on the fly", I don't remember about mem requirement. Just try to be sure.

Just try on a backed up disk before try on originals one.
I used ReOrg regularly times ago for disks and harddrives
without problems.
