What I ran into was *not* a limitation in the RDB format, but a bug in the Linux implementation on it. After Joanne Dow´s change the 2 TB disk was detected and handled properly by Linux. Also AmigaOS 4.x handles those disks just well and I think also AmigaOS 3.1/3.5/3.9 supported them, but I am not sure on the details on that, it has been a long time since I last booted one of my Amiga systems. Many classic Amiga users may not deal with such large disks, but AmigaOS 4 users probably still, and some of them may run Linux on their PowerPC motherboards as well. So I think the issue is worth fixing and am looking into submitting the fix, which looks pretty straight-forward to me upstream unless someone bets me to it. Thanks, -- Martin
