One drive of my three-drive RAID5 array fails a SMART test. Looks like the
Seek_Error_Rate is very bad. (Value 1 of a with a threshold of 23, with
smaller numbers being worse in a range of, I believe 255-0). The log files of
the last four days do not show any change in Seek_Error_Rate for
this drive, but the other drives have changes with the raw values in the range
255-253. Here is the output (long, feel free to snip when replying, table is easier to
read in a non-proportional font):
