Greetings, 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 automagically? 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! :-) -- R. D.
