My cure was as follows:
Right click My Computer, select Manage. Then double click Disk Management. Right click on the bold print where it says Disk 0 or Disk 1 or whatever. I then selected "import foreign disk", problem solved.
only_m8: u should be starting ur own thread, but what i suggest is search for a recovery method/disk there a lots of solutions in this forum, although I could find or wait for such. Otherwise, like me, get another HDD and install OS on, then attach older HDD via USB or slave and it should be accessible to get data from.
