i recently stumbled on this great little tool on this page:
DiskExplorer v1.65 By Junnno
Not to be mixed up with:
JP gobler's Disk explorer and
Runtime's DiskExplorer
although it's a bit buggy. you can open and edit the HDD .dsk format easily.
With simple a drag an drop you can import and export files and directory's(Which i think is a big plus compared to MSX diskmanager.) So if you're working with HDD images a lot, you should definitly give it a try and maybe share some experiences with this program.
unfortunatly you can't make new images, so you have to have one fully functional disk image with partitions and all. After that it's easy just open the disk image with the "vmware plain disk" option select the partition(if you got more than one) and you're ready to go.
