|it may not be a dead drive, go the drive manufacturers site and download all the recovery tools from the site, it may be that you have damaged the drive id data which you can fix quite easily.|
even if you need reinstall the drive and format it, you can still recover the data with tools like file scavenger and recover my files.
there is little need for professional data recovery unless the drive is totally dead,
i doubt this is a windows problem.
do you use any partition software programs, like acronis/diskpart you can try starting from disk and running the acronis disk recovery/installation tools they may also work.
finally invest in a new drive, install your windows, it can be installed from a update dvd,(check the net for that), use the new installation to work on your old drives, there is almost always a way to recover them.
i hate computers!
but cant help myself....
