Because BIOS updates often fix corner case issues/bugs.
The BIOS release notes for this PowerEdge 2970 server:
  http://downloads.dell.com/bios/PE2970-040201BIOS.txt
includes:
  * Fixed intermittent SATA Drive B not found error.

The likelihood of a BIOS upgrade going bad if due diligence is done to
verify the BIOS upgrade is for that hardware is practically zero.
