How am I supposed to fix those blocks? I've tried with e2fsck -c -c -y 
/dev/md0  but that yields the following printout in the log.

Oct 19 18:12:13 lion kernel: hdg: dma_timer_expiry: dma status == 0x61
Oct 19 18:12:23 lion kernel: hdg: dma timeout retry: status=0x51 { 
DriveReady SeekComplete Error }
Oct 19 18:12:23 lion kernel: hdg: dma timeout retry: error=0x40 { 
UncorrectableError }, LBAsect=156145, sector=156064
Oct 19 18:12:23 lion kernel: end_request: I/O error, dev 22:01 (hdg), 
sector 156064
Oct 19 18:12:24 lion kernel: blk: queue c8828afc, I/O limit 4095Mb (mask 
0xffffffff)
Oct 19 18:12:29 lion kernel: hdg: read_intr: status=0x59 { DriveReady 
SeekComplete DataRequest Error }
Oct 19 18:12:29 lion kernel: hdg: read_intr: error=0x40 { 
UncorrectableError }, LBAsect=156145, sector=156082
Oct 19 18:12:29 lion kernel: end_request: I/O error, dev 22:01 (hdg), 
sector 156082
Oct 19 18:12:49 lion kernel: hdg: dma_timer_expiry: dma status == 0x61
Oct 19 18:12:59 lion kernel: hdg: dma timeout retry: status=0x51 { 
DriveReady SeekComplete Error }
Oct 19 18:12:59 lion kernel: hdg: dma timeout retry: error=0x40 { 
UncorrectableError }, LBAsect=156145, sector=156072
Oct 19 18:12:59 lion kernel: end_request: I/O error, dev 22:01 (hdg), 
sector 156072

This goes on for a while and after that the following appears in the log.
Oct 19 18:14:29 lion kernel:
Oct 19 18:14:29 lion kernel: hdg: status timeout: status=0xd0 { Busy }
Oct 19 18:14:29 lion kernel:
Oct 19 18:14:29 lion kernel: hdh: DMA disabled
Oct 19 18:14:29 lion kernel: PDC202XX: Secondary channel reset.
Oct 19 18:14:29 lion kernel: ide3: reset: success
Oct 19 18:14:34 lion kernel: hdh: status error: status=0x58 { DriveReady 
SeekComplete DataRequest }
Oct 19 18:14:34 lion kernel:
Oct 19 18:14:34 lion kernel: hdh: status timeout: status=0xd0 { Busy }
Oct 19 18:14:34 lion kernel:
Oct 19 18:14:34 lion kernel: PDC202XX: Secondary channel reset.
Oct 19 18:14:34 lion kernel: ide3: reset: success
Oct 19 18:14:40 lion kernel: hdh: status error: status=0x58 { DriveReady 
SeekComplete DataRequest }
Oct 19 18:14:40 lion kernel:
Oct 19 18:14:40 lion kernel: hdh: status timeout: status=0xd0 { Busy }

And that goes on as long as e2fsck runs. So it takes forever just to 
check a couple of blocks and as it has to check > 78E6 blocks it will 
take weeks.

Is there something wrong with the drivers or the controller or the hd:s?

Please CC me as I'm not on the list.
