disk i/o errors on mac os 10.13.6

I have a corrupt disk on mac os 10.13.6 and I am not able to repair using single user mode and fsck OR disk utility repair options.

I am also not able to use reinstall OS option as the disk is not mounting.

Is there any way I can reinstallOS without having to format the disk? I need to save my photos which are not backed up.


iMac 27″, macOS 10.13

I/O errors indicate the hard drive is failing. Your options are to either install macOS to an external drive and boot from the external, or have the internal drive replaced with an SSD.
