I'm glad to hear that you got most of your data back. Sad about the lost bits. I had a similar situation happen to me a few years back (10 years+). I was running win3.1 and needed to do a reformatting, due to a bad file table/ boot record, for the primary partition. I did everything I could to make sure that my important data files were going to be retrievable after the reformatting. I only had that one hard drive at the time (I was a kid), so my options were limited to floppies - ouch.
I used a file separator and a compressor ( drivspace + winrar- or something like it) to get some of my most precious data backed up, and used a partition recovery file sort of thing to allow me to recover my secondary partition after all was said and done.
Sigh. Through all my planning and careful work, I couldn't recover my data after reformatting the primary partition. I couldn't recover the secondary partition because, even though I had the partition data, I couldn't mount it without destroying its contents because it was a compressed partition and drive space couldn't mount it without formatting. To top it all off, I couldn't get the data off all my floppies to reassemble them. I forgot the reason; it installed an older version of drivespace than the one I used to back up my data (not sure how that happened). So I was essentially screwed until I could the right drvspace installed. I fortunately got a copy of win95 a few months later (xp came out and someone I knew gave me her old win95 disk) which had the right version of drivespace on it. But the utility I used to spread my data across disks wasn't win95 compatible! - at that time.
I ended up keeping those floppies and hard drive sections intact for a number of years afterwards, in case some way for me to recover the data came up.
Microsoft finally released a hardware visualization utility to all winXP users. I used this to install a copy of windows 95 on my xp machine. After getting all the programs working in windows 95, I plugged in my old data... CORRUPTED! Almost all of it! I could recover a few wallpaper images, but nothing really wanted.
I'm a little older and a little wiser than I was when I first backed up the data. Looking back, there was really only one piece of data that I really wanted; a cute little song I found on the internet, when I was young (and so was the internet).
Throughout the years I've done numerous searches on the few lyrics to the song I could remember. About a month ago, I refound it using dogpile.
All in all, I got what I wanted the most- that song. song name= "Ballad of O old cap'n bob" artist "Alex Wilson" website "AlexWilson.com".
It's not a great song, but it brought back memories, and it felt good to finally get it back. Visit the site to hear what I'm talking about.
