pantner Posted December 5, 2011 Posted December 5, 2011 Here is the smart report for one of my 2TB Seagate LP drives Now, im not the best at reading these (ie, do i look at raw value or value/worst), but i think 1 & 7 are very bad. Just looking for confirmation. The drive gives errors in UnRaid smart.txt
Joe L. Posted December 5, 2011 Posted December 5, 2011 Here is the smart report for one of my 2TB Seagate LP drives Now, im not the best at reading these (ie, do i look at raw value or value/worst), but i think 1 & 7 are very bad. Just looking for confirmation. The drive gives errors in UnRaid You look at the current normalized value compared to its corresponding failure threshold. The failure threshold for "1" is "006" and the current value is "117", the worst in the past was "099" . Both are higher than the failure threshold. The manufacturer therefore thinks its raw-read-error-rate is within limits. The failure threshold for "7" is "030" and the current value is "078" so again, it is within the limits set by the manufacturer. (All drives have raw-read-errors. Some report them, some do not unless the re-read fails. The RAW column for many columns is meaningless to anybody but the manufacturer, and they don't tell anyone how to interpret them. To illustrate, look at the raw column for "head-flying-hours" Its value is "156740536507884". Even if that was millionths of a second, it would represent 4,966.9 years. I doubt the disk has been spinning that long. ) According to the SMART report, the disk has not failed. That could easily point to cabling picking up induced noise, or a marginal power supply. You need to post a syslog showing how unRAID is seeing and reacting to the errors. (It might be resetting the disk controller any making subsequent attempts to get to the data) Only that will tell you what is actually happening now that nothing is glaringly bad in the SMART report.

pantner Posted December 6, 2011 Author Posted December 6, 2011 Thanks for the reply. Will try changing the SATA cable when i get home. However, i do think there is something going on with the drive. The drive is in a hotswap cage and the status light for the drive is orange. If i move the drive to another tray (and therefor another sata cable) the orange light follows the drive. I was also doing a full seatools for windows test, i left the machine too long and the drive went into standby, when it spun up the computer bluescreened. Will be doing that again soon (maybe tonight). I will turn on my array again and see what happens, if there are errors i will post my syslog.
pantner Posted December 7, 2011 Author Posted December 7, 2011 well, going with my gut, i bought a new Seagate 2TB drive on the way home (if the drive is ok i just expanded my array by 2TB ) so far everything is good. The light on my hotswap cage is now green instead of yellow and when i left for work this morning the drive had almost finished 1 preclear run. The 2TB here got to step 2 and then said "This drive cannot complete a preclear" or something similar. Ran a full seatools test overnight and it passed ( ) Started a second one before work, will check it today. If it passes i will do a full format and see if that errors, i have a feeling the problem might present when writing to the drive as (i think) step 2 of the preclear process is writing to the drive but step 1 is just reading?
