Greetings--
I'm having a rather strange problem with my Rainbow 100A (well, 
actually there are other problems as well).  I recently installed an 
ST-225 which was previously used on a Pro-350 for a number of 
years.  I was really happy to finally have a hard disk for the 
Rainbow.  But when I ran DEC's HD partitioning & formatting 
software it refused to recognize the correct size of the hard 
disk.  It only allowed me to format the HD to partitions totaling 
10 Mb.  The ST-225 is a 20 Mb disk, I'm quite certian.  So I went 
ahead and partitioned and formatted my hard disk, ending up with 
two 4.8 Mb partitions but with the intention of reformatting as 
soon as I found a better utility.
 
Enter WUTIL311.  I ran it expecting to reformat and repartition 
correctly all 20 Mb and to my dismay WUTIL told me I had a RD50 
10 Mb hard drive and refused to allow me to create any new 
partitions.
 
YEAAAAACCCCHH!!!  What can I do to make full use of the 20 Mb I 
have ?
 
Is it a function of the controller card?  Could my BIOS be too 
early a version?
