I have a seagate momentus 7200.4 (Device Model:ST9320423AS)that I've checked SMART values on, and the POH count seems impossible. It lists: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 9 Power_On_Hours 0x0032 094 094 000 Old_age Always - 80990198306271 I've checked around the websites and I can't seem to find anyone else reporting a drive with such a large Raw Value. I am checking this hard drive for another user doing an IT function, so I don't know what use has been made of the drive. Any ideas how/why such a large value would report? Thanks in advance - _________________ |

Thanks in advance - Decimal 80990198306271 happens to be hex 0x49A9000015DF, and the astonishingly exact pattern of four non-zeros followed by 4 zeros IMHO is *VERY* suspicious. IOW, does a Power_On_Hours value of 0x15DF (5599 hours, i.e. 233 days or 7.7 months of *total* use) make perfect sense? If so, then either: - this HDD has firmware corruption - there are some specific flags placed in upper 32 bits storage - this HDD series has a systematic difference in use of this flag - ???

May be the same format used by SandForce based SSDs: 32-bit hours + 24-bit milliseconds count. The milliseconds count also uses the reserved byte not visible here. Please try whether '-v 9,msec24hour32' option produces reasonable output. I would recommend to update to smartmontools 5.43 which has a more suitable default for attribute 9 with nonzero high bytes ('-v 9,raw24(raw8)' instead of '-v 9,raw48'). Thanks, Christian |

That amount of POH time is possible, but not what I would expect. The drive contents appear to have been wiped, so it's possible the user would have wanted to change the SMART data but I don't know a way to easily do that. You know of a way to easily manipulate?
