The symptoms indicate to me that SMART might be an issue.

Gibbs; mmadore@aslab.com Subject: Re: Reproducible SCSI Error with Adaptec 7902 Hi, We have continued to try and get to the bottom of the problem we have with the Seagate ST336607LW drive with an Adaptec 7902 SCSI controller under Linux on an SMP machine. We have recently tried the latest Adaptec Linux driver (1.3.4) from Justin Gibbs who is one of the Adaptec SCSI driver developers. This has stopped the drive locking up but now lists SCSI errors in the log files. I enclose a portion of this log file. I have run the error logs past Justin and he has stated: "The drive has unexpectedly dropped off the bus during a connection. Without a SCSI bus trace it is impossible to know why the drive might have done this or if perhaps a glitch on the BSY line is causing the controller to detect a spurious busfree." My current conclusions are: 1. The Seagate ST336607LW drive has a bug where in certain circumstances the drive can lock up, with LED on. In this state it will not respond to a hardware reset and a power off/on cycle is needed to reset the drive. There is a difference between the way the Linux Adaptec AIC79XX 1.1.0 driver and the 1.3.4 driver handles a SCSI error condition that triggers this behaviour. 2. There is a problem with one of the following: The Seagate ST336607LW drive, the Adaptec 7902 SCSI controller on the SuperMicro X5DA8 Motherboard or the Linux AIC79XX driver that causes a SCSI bus fault. I am now giving up with Seagate ST336607LW drive and intend to try a Maxtor Atlas 10K IV drive instead. I include this information to hopefully assist others who may encounter this problem and to list the bugs so that those who are in a position to fix them know about it.
