Last night/this morning my server popped up an error and disabled one of my disks as it couldnt be writen to. I disabled the drive, ran an extended SMART test which suggested the drive was OK, and went to re-enable the drive in the array.

 

This evening when I went to add it back to the array the system went into a "read check" and spat out thousands (over 2 million in a few mionutes) of errors on 'disk0'

 

I have since canceled the read check as it seemed to have stalled the system. 

 

Am i correct that the most likely problem is a cable/set of cables, or possibly the sas controller or port multiplier? I have been rejigging the server for a few days now, and am not sure which drive is where physically or on the controllers

I currently have the system up, but have disabled any downloading to try and keep the data as static as possible until I hear back from the gurus here

 

Looks like a connection problem, check/replace cables/slot on party and try again.

Thanks. I just reseated everything and it seems to be doing the read check without errors now.
