=Troubleshooting/Repair=
+
===Noisy Disk Drive===
+
Silencing the noisy PCjr disk drive is as easy as lubricating two rods
+
inside your computer. The drive head carriage hangs on two rods and
+
sometimes hangs up, causing the noise. The rods are lubricated with Silicone
+
grease or Teflon oil. Radio Shack sells the Teflon oil as "Pecision Oiler".
+
Machine oil (3-in-One) is ok, but may cause some corrosion and generally
+
won't last as long. One final caution- Don't touch or get any lubricant
+
on the drive heads themselves.
