Since you haven't mentioned what drive you have, I assume its either an 9121 or an 9122. If its an 9122 and you do not have the EMS ROM, you are in trouble.
The 9121 drive uses single sided double density floppies.
The 9122 drive uses double sided double density floppies. By contrast modern PCs use double sided, quad density floppies.
A quick & dirty way to test the drive is to use some tape to block the quad density hole on your floppy (on the opposite side from teh write protect slider), but you really should just go and buy a bunch of double density floppies from eBay.
Now a small plug for my web site, www.series80.org. Now that you have a floppy drive, you may want to start thinking about transferign programs and data from other systems. Chack the page

for tips on transferring diskette images to Series-80 diskettes.

PS I have no idea what the four wires are for. They are not standard on the HP drives I am familiar with.
