:^/ Drive D: is unformatted....

:^/ I recently shut the lid of my Dell XPS M1210 laptop while Windows XP was shutting down. The next day Windows reported that drive D: was unformatted, and invited me to format it.

What tool exists on Windows to examine the disk, calculate the correct structure for Master Boot Record, and repair the damage thereby, leaving the files in place instead of erasing them as formatting wold do? This is easy on Linux or Amiga OS, but I am unaware of any Windows equivalent.

;^) Thanks....
