First I am NOT a computer guru at all. So take what I say with a grain of salt. But I have had 2-3 computers go down that had critical files I needed. Last time The hd would not accessthe boot drive or some such BS. I bought ahard drive reader. You simply remove the drive and insert it into the reader. It has cables on the exterior that you can then plug into a working PC. Then you can search and copy the necessary files elsewhere. I have since gone to a server with mirrored hard drives and automatic daily backups.
I have a HD reader I would be happy to loan you. PM has f you’d like to borrow it or Id give you my number if you wanna call.
Thanks
I have an external SATA case with a 1tb internal drive installed. I've used this a while back, but now I have several of the smaller 2.5" USB powered external drives, 1tb, 2tb and a 4tb. Can't seem to refuse a great deal on them...

I took my SATA case and removed my 1tb and plugged in my failed 2tb drive. When powered it spins up to rpms, but it will not read the boot/start sector and will not show up on my file manager through the USB cabling. I can feel a tapping and clicking in the drive from the head hunting to boot, but it never connects to get it booted up. I have the USB 2.5" 2tb ready to copy to if I can get the old internal drive to catch and boot.
I do very much appreciate your offer. But I think what I have is what you have only with a case. I'm drive poor right now. I want to buy another 2tb SSD for my iTunes so they'll be a bit safer and probably do the same for the videos if and when I can get them off the non-booting 2tb drive.
I've come close to just giving it a good wack, but it would be my luck to see smoke come out of it and be done forever...

Thanks again and appreciate your experience.
Have a great evening.
