Hello, i changed the sata cable and upgrade kernel to latest. If i now copy files i got a new failure: XFS: Internal error XFS_WANT_CORRUPTED_RETURN at line 348 of file /build/linux-nBoDV9/linux-3.16.3/fs/xfs/xfs_alloc.c. Caller xfs_alloc_ag_vextent_size+0x569/0x6c0 [xfs] -------------- I found a forum thread in which another solved the problem and i am not sure, but perhaps i have the same problem.
