There is something not right with the second partition on your HD:
Aug 15 01:16:34 sme7 kernel: hda: read_intr: status=0x59 { DriveReady SeekComplete DataRequest Error }
Aug 15 01:16:34 sme7 kernel: hda: read_intr: error=0x40 { UncorrectableError }, LBAsect=42414437, sector=42414437
Aug 15 01:16:34 sme7 kernel: ide: failed opcode was: unknown
Aug 15 01:16:34 sme7 kernel: end_request: I/O error, dev hda, sector 42414437
Aug 15 01:16:34 sme7 kernel: raid1: hda2: rescheduling sector 42205592
Aug 15 01:16:34 sme7 kernel: raid1: hda2: redirecting sector 42205592 to another mirror
Aug 15 01:16:36 sme7 kernel: hda: read_intr: status=0x59 { DriveReady SeekComplete DataRequest Error }
Aug 15 01:16:36 sme7 kernel: hda: read_intr: error=0x40 { UncorrectableError }, LBAsect=42414437, sector=42414437
You could try another IDE cable but you probably need a new HD.
