I have a Seagate Barracuda 7200.9 family harddisk of 160gb capacity which is more than 3 years old. recently I installed gsmartcontrol and after running it, it showed number of current pending sector count and offline uncorrectable sectors as -- 4294967295.Fearing the disk going bad, i backed up data and started monitoring it. This is the latest gsmartcontrol shows - http://img820.imageshack.us/img820/5707/201010161300051280x1024.png
After two weeks, the no. of bad sectors is the same and the disk shows no sign of failure (at the least there is no problem to read or write files from or to the disk).hence I am confused .is the disk going bad ? if it is fine why can't it remap all those bad sectors ?
I have found the smart reporting of seagate barracuda drives to be flaky at best. (but I always back up and monitor as well) I have 4 spinning in 2 dmraid arrays on a backup server, and sometimes it just throws errors. (it has done that for years) Drive info is: === START OF INFORMATION SECTION === Model Family: Seagate Barracuda 7200.11 family Device Model: ST3750330AS Serial Number: 5QK0Q09G Firmware Version: SD1A User Capacity: 750,156,374,016 bytes Device is: In smartctl database [for details use: -P show] ATA Version is: 8 ATA Standard is: ATA-8-ACS revision 4 Local Time is: Sat Oct 16 11:59:51 2010 CDT SMART support is: Available - device has SMART capability. SMART support is: Enabled There have been a number of firmware changes/updates for seagate drives over the past 3 years and several "bad runs" of disks. Check the seagate support site and make sure you have the latest firmware for your drive. I have had the bad sector errors - sometimes a true failure, sometimes not. Just backup, monitor and if you continue to get the errors, drop of $50 on a new 1T drive. -- David C. Rankin, J.D.,P.E.
