I want to know what you guys think could be the problem, and how to safely test cables by switching them around. I do not wish to endanger the array, so i want advice on how to troubleshoot safely. I want to make sure its the drive before I Buy a new one.

I have 4 drives connected to a 3Ware Escalade 8500 8port Sata Raid5 controller. I use ports 1,3,5,7. Here is the log

The first thing i want to do is just change the cable on port5. I figure it cant hurt. Beyond that I am not sure if there is anything aside from replacing the drive that i can do.

Comments and advice appreciated.

I finished installing the array on July 17th, thats the final time i restarted. I wont repeat errors just bold them the 1st time, and truncate any following. Soft reset means reboot.

Did you change the cable on Port 3 or Port 5?

It looks like it is the one on 5 that is having the problems.

That made the array not fault tolerant...

When i changed the cable on port5 the drive was no longer in use by the array. I told the array to rebuild and will see what happens. Im glad its ONLY the 1 drive ^^

Why would the drive no longer be recognized as part of the array ?
 
Any number of reasons can cause the drive to not be recognized temporarily.

The drive may be dieing, or the cable may have a bad wire etc.

if it happens again, I would consider replacing it and using a new cable (perhaps even on another port on the 3ware card)

Thanks mucho for the references. I will look a bit more into shielded cables since there is no way with 2 PATA and 4 SATA drives i can keep the wires from mixing.

I tested 2 cables, and 2 ports on the controller. I have no doubt that my HDD is borked. I will RMA this when i can replace it. Later I will use it as a hotspare.

I really appreciate the quick replies. This is hardly a minor screwup, and I was in a bit of a panic. Having calmed down I have already placed the order for a new drive... and some other oddities from newegg.
