Never used BIOS partition till now, but on the other hand, I've never
used 3TB disks. Debian reserve 1MB on start of the partition, but I
guess that part is used for MBR. But it wasn't hard to find necessary

Didn't think it would took that much time to sync empty disks, but now
it does make sense.

I've tried BTRFS in testing environment, it worked well, but I wouldn't
use it until btrfsck is ready and stable.
