Imaging MFS Disks with DC 4.2 in OS9

I've been imaging 400k MFS disks with Disk Copy 4.2 on my Wallstreet G3 running MacOS 9.2.2.

The disks image fun, but DC 4.2 doesn't recognize them and names them -not a Mac disk-.image or some such. (MacOS 9.2.2 cannot read MFS).

But DiskDup+ 2.9.2 will recognize the disk name and save the image as "Word Master.image" or whatever.

Regardless of which format I use to image, the disks always run fine in Mini vMac AND get recognized as Master Disks by the application software. Seems to be a perfect solution.

Any reason not to image 400k MFS Master Disks with Disk Copy 4.2 in MacOS 9.2.2?

If you still get mountable images in Mini vMac this way I can't see a reason not to use DC-4.2

At the very least, tag data of 400k & 800k disks will be preserved by Disk Copy 4.2, which may be of interest to historians now and in the future. I'm not sure if DiskDup+ will do this. Another tool that will preserve tag data is ShrinkWrap version 2.1 (when it saves to DC-42 format), but not the later 3.x versions.

Another tool you may find time to look at is DART, which was distributed to Apple Developers and internally, only. It too preserves tag data and can copy 400k media and more. I don't know how it fares under OS 9 but it may be worth a look. Disk Copy 6 can read and mount it's disk images, and other programs that can too, are listed on the DART page.
