[smartmontools-support]Seagate SCSI drive, lots of increasing corrected errors?

[Rob M. <rm...@le...>]

Hi,

One of our servers with a SEAGATE ST336607LW SCSI drive shows a rapidly
increasing number of Fast ECC corrected read errors (12+ million). The
number seems to increase by 10-20 every few seconds. Is this indicative of
a problem? I will paste the output of smartctl -a below. Short and long
self tests reveal no problems.
