I clicked on the above and found that I have already pressed the "Ask a Question" box, so if there is a separate cubbyhole for all this, TR didn't make it clear, unless it is in the Blog box, where I didn't want to go.
I am not so much concerned about recovery at this point, as there's not much left to recover; I'm more concerned about the next time, when I might have 100 gigs at stake instead of 20. There's plenty of good programs out there which will help you find old files; the problem, it seems to me, is in making them useful by plugging them in again. What happened was a lot more complicated than what I said; I just didn't want to start by writing a chapter about it. The first crash was to my laptop, which I thought was safe because only I use it, and I had good antivirus and anti-spy-spam etc. installed, firewalls, the whole nine yards. Then I found EasyCleaner, and happily started deleting useless info; I think my problem started when I cut my startup prompts to a minimum, which made one of the large software companies mad (I'm not sure which one; I have about five candidates); because after I reinstalled I found that a malicious double minidump folder had been downloaded into my Configuration settings, which would be easy for anyone who already had access to the registry, without a spyware or virus alert.
I'm sure about this, because I copied the hard drive to my desktop trying to find the problem, and it also became infected; so I had to do two reinstalls, one which already had XP Home, the other over XP Pro.
Now comes the curious part: in both, one which was more of a repair, and the other more of a reformat, there were some programs lost; and there doesn't seem to be any rhyme or reason as to what works and what becomes disconnected. In working with a few recovery programs, occasionally a random fragment or orphan file will reconnect; but with the hundreds of working files for each program, it's nearly impossible for me to understand why some made it through the reload, and others didn't. For now, I would be happy to know where the encrypted keys are kept, to see if I could recover my large folder; none of the normal procedures have worked; it's hidden much deeper than that.
