Is My Hard Drive Dead or Can It Be Saved?

I started my PC yesterday, and it showed a "Fixing D drive" message, attempting to scan through my files with an estimated time of about 15 hours. I let it go for a while, but I noticed it was progressing super slowly. Unfortunately, I had to turn it off due to other commitments. When I started the PC today, the fixing message was gone, but the Windows logo took longer than usual to load. Once I got into the system, everything was incredibly slow; every action caused lag, making it impossible to open anything or even shut it down. I checked the drives in File Explorer, and while the drive was still listed, I couldn't access it or run CHKDSK. It just showed the name of the drive without any storage info, and the applications that were on it had lost their icons. After I removed the drive, my PC booted up fine without lag. So, is the hard drive dead or can it still be saved?
