Thanx HartyBart, yeah, it's the old Smith Micro version.  I didn't have a problem inputting the serial, I think, but if I read your second para right,
Bondware?  Is that the company that the current Poser is made by (P12, if I recall).  It's just that there's no Smith Micro website to activate it now.
Can't recall if the new company started with P11...it's been awhile.

As to the HD, I think I did try TestDisk; didn't work either.  see, I was fooling around trying to create a 'double boot' system, and not knowing one jot about partitioning, It all went downhill from there.  I have the old drive in a USB outboard enclosure by Sabrent.  When you turn that on, it does make that usual spinning up sound, and no other unusual noise.  I put in on the computer it came out of.  Many months earlier, I attached it to a laptop, and the laptop 'saw' folders, but when I opened
them in Windows Explorer, they turned up empty.  At some point, the laptop, running Win 10, offered to format it, but at that point I wasn't ready to give up on 9 or so years of accumulation of programs, etc..
