Here are all the errors (when reading/writing heavily):

[4294810.556000] ata_gen_fixed_sense: failed ata_op=0x35
[4294810.556000] ata4: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ
0xb/00/00
[4294810.556000] ata_gen_ata_desc_sense: failed ata_op=0x51
[4294810.556000] ata4: status=0x51 { DriveReady SeekComplete Error }
[4294810.556000] ata4: error=0x04 { DriveStatusError }
[4295514.668000] ata_gen_fixed_sense: failed ata_op=0x35
[4295514.668000] ata3: translated ATA stat/err 0x51/04 to SCSI SK/ASC/ASCQ
0xb/00/00
[4295514.668000] ata_gen_ata_desc_sense: failed ata_op=0x51
[4295514.668000] ata3: status=0x51 { DriveReady SeekComplete Error }
[4295514.668000] ata3: error=0x04 { DriveStatusError }

Jeff/Mark, from these errors can we reach a consensus as to the cause of
these errors and how to eliminate the problem?

Thanks,

Justin.
