Hallo,
I'm just copying about 1.5 TByte from a 3-disks-btrfs directory (data:
raid0) to another disk. And there seem to be 2 damaged files, they stop
the copying process.

The files contain no valuable data (*.mpeg files, reproducable). But how
can I tell the disk not to use the damaged sector(s)?
On an ext2/3 system I used "badblocks" - is there some comparable tool
for btrfs?
Viele Gruesse!
Helmut
