In the meantime, I've got a suitable new disk and copied the data to it using ddrescue (it took about 12 hours for 1TB). The disk had one fault extending over a few successive sectors. For some reason, I had to repair the first partition, which I use for swap. The large second with btrfs on it seems fine. I ran btrfs scrub on it and it found one error: Apr 16 09:48:27 fuchsia kernel: [ 6792.829186] btrfs: checksum error at logical 74443923456 on dev /dev/sdb2, sector 145398288, root 1228, inode 59102093, offset 929792, length 4096, links 1 (path: usr/lib/debug/.build-id/8f/b82df57b7b6fff7033f6abd7de914b82f98160.debug) That file is part of a "historical" snapshot which I have deleted by now and thus presumably dealt with the problem.
