Have just found a cure posted in BAO official forum...
Sort-of-laborous, but it seems to work. Kinda suspicious to mix ASPI drivers, but the other solution would be hacking Adaptec's wnaspi32.dll and make it report a higher number than 4.60.1021.
I'd like to avoid that too (as well as installing 4.7X), I guess that i could wait for a fix, but it's always curiosity that kills the cat...
I have also noticed that DiskDump has been removed as a reading option, but considering the new law(s) about disk duplication I guess it's rather easy to explain that "omission"...
