External hard drive clicking and not recognized by mac will DiskWarrior work?

First of all apologizes if I've posted in the wrong community I couldn't find one that really fit my particular query.

I'll give a quick rundown of what happened and see if anyone can help or suggest a course of action. My Seagate External HDD model SRD0SP0 was mounted to my 2013 MacBook Air when it started to make a loud noise freezing the computer and requiring me to force shutdown the entire system. I immediately rebooted the computer and it started up again fine but when I tried plugging in the drive to the USB it would only spin and beep at regular intervals and then go quite. The drive did not mount to the desktop but I could see it in DiskUtility although the 'verify' and 'repair' options were greyed out. I tried to connect to a PC but it would not recognize the drive either. I left the drive alone for a few months and now when I plug it in it starts to fire up with the whirl sound but that is quickly followed by 5 faint ticks followed by a louder click. It almost sounds like something is dragging and the click is it coming to an end before starting up again. (I have a .m4a recording of the this but I don't see an option to upload) This goes on for about 20 seconds and then a window pops up saying something along the lines of 'this disk is not recognized by this computer' and the options to 'initialize' 'ignore' or 'eject'. I have only ever clicked eject. As before the drive is visible in DiskUtility but the options are greyed out.

I contacted a data recovery agency and their response was:

I would recommend to remove bare drive from the External casing and connect it to a computer directly or via another USB enclosure. If the drive is internally fine you should be able to see and copy the files. If you still get the same symptoms then your clicking hard drive most likely has internal problem with read/write heads and needs head assembly swapped from a donor. It's a very serious problem and recovery procedure in this case requires a lot of experience, use of class 100 clean room and specialized equipment.

If stored files are not particularly important you should replace the hard drive. If you need data from the drive we could recover it for $950 USD.

At this time I am not comfortable taking my drive apart and I can not afford close to 1k in repair costs. From my research on this forum I have seem multiple suggestions to try DiskWarrior but I am not sure that it will work with the problems that I am describing. Before I spend the money has anyone had a similar problem and had success recovering their data via DiskWarrior? Or do I have to resort to the data recovery agency or the freezer technique?
