I am tryinf to ugrage a BCM400 3.6 to 4.0 today. Part of the pre-upgrage tasks list that the C,D,E,F,G,I drives must be "exactly" a size. These sizes range from 1 gig to 10 gig and all of my drives in the 3.6 are short from 24 meg to 221 meg. Has anybody tried this anyway and it work or should I not proceed?
