   Dave can you give a bit more detail?  I had a look at the specs and it said   
   the device was "OS independent".  1. So are the volumes under the control of   
   OS/2?  I mean does it handle Extended Attributes (EAs)?   
      
   2. Is the eSATA connection via an on-board SATA port?   
      
     If such a set-up can handle EAs it could function as a daily use working   
   RAID disk(s) but if not you'd only protect yourself from disk collapse by   
   regular backups to them and with BA2k one would still be hamstrung with its   
   2.1 GB limit (although on a daily basis you wouldn't normally generate 2.1   
   GB!).  However, you'd still be troubled by the management load dealing with   
   accumulating backups as I've discussed in another post.  The RSync approach as   
   Doug Bissett discussed would only be valid if the setup could handle EAs?  Not?   
      
     What I would like is a daily use RAID disk setup with full OS/2 filesystem   
   capabilities where you could work away without the constant risk of a disk   
   collapse.
