Hello, I'm running an old Pentium based machine with three hard drives installed. Two of them are not in smartmontools' drive database, so I think you might like to add them! The output created by smartctl -a for these drives is attached to this eMail. As you can see, the Power_On_Hours act a bit strange for the 120 GByte drive (hdb): It seems that the drive doesn't report minutes, halfminutes or seconds, and my calclator told me that this counter isn't reset every 1092 hours as suggested in the FAQ on the smartmontools web site. For both drives, the LifeTime printed in the self-test log seems to be OK - short self tests are run every six hours by a cronjob. regards, Jan |

You are having the same issue reported under 'Maxtor drives' in the FAQ. Your 120 GB drive is 6840 hours old. 6840*64 = 437760 'maxtorminutes' Attribute 9 keeps this in a two-byte RAW value that rolls over every 65536 'maxtorminutes'. Hence the counter has rolled over 6 times, and the current value of Attribute 9 is 437760-6*65536 = 44544 'maxtorminutes'. > For both drives, the LifeTime printed in the self-test log seems to be > OK - short self tests are run every six hours by a cronjob. If you watch over the long term you'll see that they advance 7% too slowly since a maxtor minute is 64 not 60 seconds. Bruce |
