Snipped log info:

This is the output of "cat/proc/partitions"
major minor  #blocks  name

   2        0          4 fd0

I'm getting totally confused !  I was sure that I had two 500Gb HDD in 
this machine, but it seems not.  It also seems that the 200Gb HDD is 
swap, boot and root drive and that sdb is home.

PS.  The machine booted up as normal this morning...

Thanks:
