I have a friends Seagate Barracuda 7200.11 500GB. it was in his HP Pavilion Elite m9750a. Running Vista Home Premium. In the PC it would not boot past the initial splash screen. None of the "F" options were operational. I have removed the HDD and placed it in a "Dock". Still windows [XP this time] will not recognize the drive, neither will UBUNTU .... I booted UBUNTU from a CD. Does anyone have a suggestion for me? I do hear the discs inside spin... Can anyone have a guess at the cost of data retrieval? I have considered that changing the logic board may help... Any advice or assistance would be appreciated
