Dell 537 was getting "Unmountable_Boot_Error and Status 79 during a self test. Dell is sending a new hard drive. Put the Dell drive as a secondary hard drive in my Acer, but will not allow me to access the drive. It says I have to format it first. I just put another hard drive as the secondary driver with no problem accessing the information on the drive. At this point, is there another way to get some files off the bad drive? I was told there were some letters that need to be recovered if possible. She may willing to pay someone if that is the only option on recovering the data.
