We've had quite a lot of post on this during this year.
I did not want to use a utility outside W7, so was determined to make the change using MS product only.
It seems W7 plonks some files up at that end, and there they stay. I finally stripped the disk and changed it before the OS had been re-installed. Needles to say, I wasn't worried about the data on the other partitions.
Here's one of many.
Determined to clean-install W7, and even more determined to have 100gig C drive plus two others, I fitted a second hard disc and attacked the main drive with the XP that I was now running on. Cleaned out C by deleting the partition and making a new one c 100gigs. Fine. But...
When W7 installed, I'd hoped to expand D into the space. Totally barred from creating a new primary drive cos the 100mb system file was counted it seems - and this barred me cos of the total count exceeding 4. (had to leave F for a while) LSS I shoved data about so that I finally got the drives I wanted. C D and E. However, it soon became apparent that a great deal of data was simply missing.
Often, when we move files from folder to folder, the data is not really moved- just the addresses reset. . . or so I gather. But when the data is going from one partition to another, I'd assumed that it was really rewritten, indeed the HD light was flickering fit to bust. If the data wasn't truly rewritten, then when I removed the partition to meld it into the other unoccupied space, the data would have been lost I assume.
This is a bad effort. #3 post is very confusing - even I can't understand what I was getting at.
However, there may be a few clues there.
