Thanks for the tip!  We ended up paying a third party vendor, Reliant Technologies for the drive.  I installed it this week and its working fine now.  We are looking at getting their very basic level 4 support contract.  Because the NX4 is an older unit, EMC support is very cost prohibitive, but this vendor has a positive track record and we will use them for older equipment.
I have an array where one of the vault drives failed.  The poor part with this is that write cache is disabled so it really reduces performance.  I only had 2 VM's running on this but I vmotioned them to our VNX5200 to remediate.  However we would like to fix the drive issue.  Drive 2 is faulted which is an STE3065 CLAR300, CLARiiON TLA Part Number: 005048956.  I was wondering if I could just purchase a brand new Seagate 300GB 3.5" drive and replace the bad one in the existing drive tray and use it?  Its $199 at PCM.  Would this work?  See the part number contains some of the same numbers ST3300657SS   [URL]~dpno~8019871~pdp.gaegibi?src=search
