Reading HP 16500 Logic analyzer firmware disks

I have a number of 16500 floppy disks I'd like to digitize, and am wondering what the best way is to image them. I will probably want to look at them if possible if they are FAT, as some are, so having a flat image would be nice. I'll look into the prior postings for software to image them for reproduction. I just tried a DD from one attached as an experiment in this way, and did not get a good result: Macbook Pro running Mavericks Vmware Fusion. Ubuntu 10 Teac USB floppy drive attached thru to the Ubuntu machine. The floppy drive showed up, but a DD only copied in about 1mb from a 1.44 format disk. Not sure what quirk that was from. It's been a long time, and even though I follow your discussions here, I'm not sure if this pile will work. I have a Linux Laptop and also a windows Laptop (XP) which I'm going to try. thanks JIm
