Mac wasn't starting up and now I have non working Disc0s4

Yesterday I reboot the computer and it wasn't starting up. It was stuck in the opening screen with the apple loading.
I tried to reboot on verbose mode and it was stuck in a "disc0s2" error.
After around two hours running on verbose mode showing the error, the computer finally iniated.
I backed up everything and then I went to the Disk Utility to verify and repair everything. There I noticed my mac is divided now in two folders:" Macintosh HD" and "Disc0s4".
I could verify and repair everything on Macintosh HD but when I tried to do with Disck0s4 it pointed an error that couldn't be repaired. The message said: " Disk Utility can't repair this disk. Back up as many of your files as possible, reformat the disk and restore your baked up files".
I'm very lost. I don't really know what this Disc0s4 is. I'm afraid of reformating it and loosing data and also afraid of turning off the computer and having the same problem to turn it on again.
Also I noticed the sound is not working now. I went to the "sounds" on system preferences and says there is no sound inputs.
I don't know if I should reformat, I don't know how to reformat and I don't even know if I reformat I will loose data...
Can someone please help me with this and tell me what exactly is going on?
Thank you SO much for your attention! I really appreciated!
