@ndavis31209 I use this site to get the boot disk images for my vintage computers. Under the MacIntosh link, you'll find the disk images and the instructions on how to use those.
As for your drive. Time do disassemble your Mac and time to take a look at what is going on. Double check your ribbon cable and triple check your power supply. It's about time that some of the caps etc may just fail. Let us know the exact model for your HDD. Let's see what we can dig up. Here is the MacSE manual you can use to work on getting there.
Now, with this computer you really need to use common sense. Due to its CRT, the power supply etc. Packs a punch. Make sure you discharge the CRT! Try to avoid touching anything with your bare hands until it is discharged.
Once you start working on your Mac, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
Repair is War on Entropy!
@ndavis31209 most common failure on these drives is either the controller board or the head is gummed up and does not move to read the disk. Fixable? Yes and no, you won't need a clean room. Just common sense. Let's see what drive you have so we can figure this out for you. Take a look on here to see the rubber stops that prevent the head to move. All we would need is to see your drive and controller to continue to assist you with this repair Adding images to an existing question
