  What a shame!

  I found the reason why 2940UW failed the WIDE negotiation.
  ST15150 N(!) does not support WIDE SCSI !!!!!

  Dell sells Narrow HDD with Wide Controller !!!!

  Their estimate said "HD, 4GB W/2940 CTL" so I thoght that
  HDD surely would be wide type...
  I think I am cheated..

  Thanks Paul T. Root <proot@horton.iaces.com>
