A nice fix, Eddie. I hope that the
ungraceful one has been (is being) suitably chastised!
"Scanned it in"? Ultrasound? That's advanced stuff, Mate.
It's "interesting" though that the OEM didn't see fit to bother with a database repair routine as part of his software. It would have been a nice touch, after all. Or (perhaps better yet) even have used a DOS system, which would have been a bit more "forgiving" ... or even some sort of battery-backed system (to close the files) which would tolerate "ungraceful exits" or all types!
See ... who needs "tech support" (from so-called Local Agents, or anybody else).

PS: The Del Mar Reynolds Medical of today is clearly not the Del Mar Avionics and Reynolds Medical of old! But, there again, the same may be said of many of the contemporary manufacturers, can it not? The factory is closed for summer holidays, I should imagine. I only hope they're enjoying the same lovely weather as we're having here in the UK.
PPS: I notice that Nucleus do a whole range of data recovery software, so that's a handy website. Of course, back in pre-history, we used to be able to patch .dbf files (etc.) back together ourselves, using simple tools such as the Norton Disk Editor (much more fun). Oh, happy, happy, days.
