No, I haven't tried Recuva because I read the write up on it, and it
said it was for recovering DELETED files. In my case, nothing was
deleted. I expect the file allocation table on the USB drive was
corrupted so that the files are all there, but can't be found because
their addresses have been all screwed up.
I have found two programs whose "trial" or "demo" versions allow me to
recover up to 1 gigabyte of lost data each. Since this is a 4 GB USB
memory drive that's been corrupted, my game plan is to recover 2GB with
these demo programs, format the hard drive in my computer, reload
Windows, download those same demo programs, and then recover another 2
GB of lost files. That will allow me to recover everything that was on
that 4 GB USB drive.
I have two computers and a KVM switch. I use one computer strictly for
surfing the internet, and I reformat the hard drive and reload Windows
XP whenever I get some malware on that computer. I want to reformat the
hard drive and reload Windows XP on that computer because of all of the
"free" shareware I've downloaded and installed over the past week or so.
Each one of those "free" programs has changed my home page, changed my
search engine, and loaded tool bars onto my computer that I don't want
or need. I'd reformat my hard drive and re-download only the two demo
versions that I know will recover data from my corrupted USB drive.
