[smartmontools-support] raw values – help required…

Hi! I just had to replace one of my 2.5" hard disks from my NAS Synology DiskStation DS409slim. I have four different disks, from 4 different vendors, just to make sure they don't fail at the same time. They are configured as a RAID 5 volume (so ONE disk may fail at a given time, but no more). Now, I just checked the new disks SMART values and I don't really understand the ones from my new disk: Toshiba Hornet M250 500GB MJA2500BH. Especially all values of failure, like Raw_Read_Error_Rate, Seek_Error_Rate, Hardware_ECC_Recovered, UDMA_CRC_Error_Count and Multi_Zone_Error_Rate (everything with "error" in its name), but also values like Offline_Uncorrectable, Reallocated_Event_Count and Reallocated_Sector_Ct which sound like failure too. I have a hard time interpreting these values. The other disks seem more "reasonable" to me, at least they don't report something like Raw_Read_Error_Rate RAW_VALUE=168559… One other interesting thing is that all disks (except the replaced one) where up and running for about 3710 hours. This is what they report: Power_On_Hours Disk 3710 DISK 2: Hitachi Travelstar 5K500.B HTS545050B9A300 1485 DISK 3: Western Digital Scorpio Blue WD5000BEVT 3712 DISK 4: SAMSUNG SpinPoint M7 HM500JI As you can see, the Western Digital drive differs alot from the value it's supposed to be. So, does anyone know how to read these raw values? I don't like reading an error rate of 168559 on a new disk. Does anyone elso have the same experience? If so, how do you know if and when the disk suddenly fails? Thanks, Andreas aka Linux User #330250 ### ### DISK 1 - BEGIN ### (new disk, just replaced) ### DiskStation> smartctl -d marvell -a /dev/hda smartctl version 5.38 [armle-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: FUJITSU MJA2500BH G2 Serial Number: ************ Firmware Version: 00000018 User Capacity: 500,107,862,016 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: ATA-8-ACS revision 3f Local Time is: Thu Apr 15 18:55:08 2010 CEST SMART support is: Available - device has SMART capability.
