Did you try ruling out btrfs as the cause of the problem? Maybe something e= lse in your system is corrupting data, and btrfs just lets you know about that. I.e. on the same drive, create an Ext4 filesystem, copy some data to it whi= ch has known checksums (use md5sum or cfv to generate them in advance for data that is on another drive and is waiting to be copied); copy to that drive, flush caches, verify checksums of files at the destination. --=20 With respect, Roman ~~~~~~~~~~~~~~~~~~~~~~~~~~~ "Stallman had a printer, with code he could not see.
