the son of the boyfriend of the woman for whom my wife works was allowed access to the company PC. Allegedly he was helping to merge data from a few systems. To make a long story short, he reformatted the drive then reinstalled XP. The PC is clean; no files, no software. Nothing except XP. Research, and discussions over the years, indicate it is possible to recover the data. Any recommendations for how to proceed? Or should they prepare themselves for hours of data entry?
