The current value is 56, the worst is 24, and the threshold is 0. These are high values. Do you mean 56, 24, and 0 are high values? Or the raw values are high? Is the raw value wrapping around? > The firmware is doing its job in that it's fixing errors. But the fact it has to at this rate is not a good sign.

If it is I'd just get rid of it. I think it's over 3 years old, so probably not in warranty; it might be if it's a 5 year warranty. Fortunately, I've already got new disks in the machine. The transition has proved challenging. I was more or less ready to go, but I wanted to do some experiments with the alignment of partitions and other parameters. Any suggestions would be great. Ross P.S. Here are the results for sdb, which has also been generating chatter in the logs. -------------------------------------------------------------------------------- on Jan 7 22:51:59 PST 2013 smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: WDC WD2003FYYS-02W0B1 Serial Number: WD-WCAY00580447 Firmware Version: 01.01D02 User Capacity: 2,000,398,934,016 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Mon Jan 7 22:51:59 2013 PST SMART support is: Available - device has SMART capability.
