Paul, the problem is with the NCL controller. It is evidently incapable of being used as a secondary controller in the system and is therefore conflicting with the other controller hooked up to the Seagate. You mentioned a Western Digital 1002 what worked. I assume you refer to the WD1002A-WX1. This controller is an MFM one capable of performing as either the primary or secondary controller in a system (and was, consequently, one of their best-selling controllers prior to the XT-GEN). My solution-suggestion: get rid of the NCL and get yourself a WX1 or something similiar. Not all (read: very few) hard drive controllers can be used as a secondary, so make sure of what you buy. NO! No! No! You CANNOT use that Microscience on the RLL controller!!!!!!! Sure, you MIGHT get it to work initially, but drive failure is almost guaranteed when you hook a non-RLL rated drive to an RLL controller! RLL and MFM are VERY different and never the twain shall meet! Same goes for ARRL and RLL. If you have any further questions or need any more help, please feel free to E-Mail me.
