I have a IBM computer thats about 20 years old and every time I boot-up the computer with the HD enabled i get a hard drive failure. Now I have to use a start-up boot disk on a 3 1/2 in. floppy. its one of those computers that have a 3 1/2 in. floppy drive, 5in. floppy drive, and a small hard drive, low memory, slow CPU, and no usb ports. Can someone help me with the HD problem?
