I have a 750GB Seagate HDD that is inaccessible. The hard drive itself is recognized in windows and shows up with its drive letter but unable to get partition info. Attempting to do ANY functions on the drive causes the associated program to lock up. Double click the drive and explorer.exe locks up, attempt to view in disk management and the management console locks up. Can't reformat, can't run recovery, can't run chkdsk etc. If I try to boot with it already connected it hangs mid post. It spools up but I don't head the telltale sound of the read/write head moving about except the initial startup. I need an injection of fresh ideas to save my data without having to spend hundreds. I have the technical skills for all aspects of data backup but I don't want to open the drive without knowing if it's the actuator or the read/write head.
