My IBM PC AT has an original Seagate ST-4038 hard drive. It spins up and the light flashes, but I evidently have some issues. I get an error that says something to the effect of "invalid media or track 0 bad". I can get the C drive to be seen, but I can't execute any commands to do anything with it. I tried to FDISK it and reformat, but it locks up the machine. I read this model has some kind of head park lock that can be initiated, but I don't know if it is a physical switch, or software lock? Could the drive be locked or is it toast?
