I've had the occasion to send a CF card out to a data recovery service. The company was fast but expensive. And they recovered most of the images recorded on the card.
But I'd like to be able to do it myself next time.
Please recommend some (preferably) OS 9 compatible software that can do that.

SUM did its job nicely with unreadable removable drives back in the day. Not sure whether SUM was aware of the USB bus, though. SCSI connected CFs would likely be fine.
IIRC one could create signatures of working drives to be used as template in an emergency.
Might be helpful to have drive templates for all type of drives you have, as the default templates may not include the more modern CF, SD, etc.
Norton Utilities and SystemWork flavors used to come with a data recovery tool too, but I found it not to be that successful.
I'd suggest using a modern computer, first creating an image of the media with a tool like ddrescue, followed by using photorec to search for images. I'm fairly certain that SUM II can't reliably operate on FAT32 volumes as it's designed for HFS (and not even System 7 for that matter).
