There are two white, 2 amp Littelfuse fuses (F1 and F2) on either side of the 69G1084 chip in the top left corner of the PCB, near the IDE connector. I can't see where F1 goes, but F2 appears to be connected to the +5V supply pins (IDE pins 41 and 42).http://pinouts.ru/HD/Ata44Internal_pinout.shtml
There also appears to be a diode (D3?) near F2. I would measure both fuses and the diode. Let us know what you find.
BTW, a digital multimeter can be purchased for US$5.
