I have os3.9 on my tower and when I try to get it to accept an old IBM 9g HD I have here....format, partition etc... using the 3.9 HDToolbox I get negative HD space free. The best I have been able to do is two 1.+gig partitions. Since I haven't found a solution the HD is sitting on my desktop as a paperweight. When I look at the number of cylinders and such in it the toolbox gives nonsensical values, most in the negative range.
