I've been a diehard Seagate fan but recently I have heard some people 
having problems with 1TB Seagate drives.    At some point the dropping 
price and the increasing density is going to become a quality issue - 
perhaps that day is close? 

Yes, I lived through the Maxtor problems also.  I got a lot less than 3 
years out of several.  Fujitsu also had a bunch of hard drive issues 
about 8 years ago.  The problem was so severe that Siemens sent techs 
out to large installations with boxes of replacement drives to do the 
swap outs before they died in the field in Industrial PC 
applications.    Those retrofits must have cost a small fortune.

Is your lathe still happily cutting threads?   I cut some axle spindles 
the other day and the first one off the machine accepted a 1" long - 
1"-14 nut perfectly.   The pitch was right on. 

I'm using a 200 ppr encoder in counter mode and the PC has no problem 
tracking the index at up to 1200 rpm so far.  I calculated a 1500 rpm 
top speed before it loses index sync.

Threading has been rock solid reliable so far.  I ran out of stock after 
7 parts.
