January 16, 201016 yr I have a drive that I wonder if it's safer to use for my unraid box. If I check the smart staus log I have some big concerns. I have still 6 month warranty left. but westen digitals diagnostics software cant find any errors. I still would like to RMA it. here is the COMPLETE log: SMART status Info for /dev/hdc smartctl version 5.38 [i486-slackware-linux-gnu] Copyright © 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Model Family: Western Digital Caviar SE family Device Model: WDC WD5000AAKB-00YSA0 Serial Number: WD-WCAS82496563 Firmware Version: 12.01C02 User Capacity: 500,107,862,016 bytes Device is: In smartctl database [for details use: -P show] ATA Version is: 8 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Sat Jan 16 12:32:29 2010 GMT-1 SMART support is: Available - device has SMART capability.

January 16, 201016 yr Other than 7 sectors pending re-allocation, I see nothing else wrong with the smart report. Looks like a good drive. Joe L.
January 16, 201016 yr Author Thanks for the reply. Sounds good, then I might try to use this drive in my Unraid server atleaste until i buy a new bigger drive. what about the errors in the log when running smart tests? Is that just an indication of the pending failing sectors?

February 19, 201016 yr Somewhat belatedly here, but I would strongly recommend running Preclear Disk on this drive, before adding it to unRAID. The AMNF errors are somewhat concerning. AMNF indicates "data Address Mark Not Found", meaning the sector was located, with its sector ID, but the start of data area was corrupted or not found, and that means the data for this sector is lost. Address marks and sector ID's are usually only written by the initial factory low-level formatting (as I understand), so it will be interesting to see if writing zeroes to this sector will cause the drive to correct the formatting and structure of this sector. Probably, it will just remap it, so PreClear will probably clear the SMART Pending count, but add a few reallocated sectors. Two interesting reference pieces I found, that should help to understand physical sector errors: * Hard Dive Physical Sector Damage - simple intro to sector structure and errors (UNC, IDNF, AMNF, etc) * Data Recovery Whitepaper - comprehensive intro to hard drive mechanics, structures, and errors (sector errors at about 45% down)
