Can somene kindly tell me how to lock/unlock the heads on a CDC model
PA5N1F15 9" hard drive? I don't see anything that looks like a way to
look/unlock the drive when I examine it; do the heads lock/unlock

BTW, according to the label, this is an FSD drive - is this
the type of interface, or do I actually have an SMD drive? Wow,
this is one heavy, and beautiful drive... looks like a cast-iron
housing too!

Since the date on the label is 1985 (or 86? I don't recall at the
moment), and the HDA media defect information sheet is dated 1998, it
looks like I've may have a relatively new drive assembly! :-)
