Check If A Hard Drive Is Failing Mac Os
If your hard drive icon doesn’t appear there, go to Go Computer, then click the hard drive icon under Devices. Click the File menu, and select Get Info, or press Comand-I on your keyboard. Hard drive recovery software can often retrieve data if the hard drive has not yet completely failed, and sometimes can retrieve data in the case of a non-booting hard drive. However, if the software is not able to scan the drive, then you can still check with The Data Rescue Center to recover the data.

And Shift-Option-Command-R isn't available. If you erased your entire disk instead of just the startup volume on that disk, macOS Recovery might.

Please help to recover data… as I do not have a back up
If you check your startup volume (Macintosh HD), make sure you also check your data volume (Macintosh HD - Data). In the sidebar, select a disk or volume, then click the First Aid button. If Disk Utility tells you the disk is about to fail, back up your data and replace the disk—you can’t repair it. Otherwise, continue to the next step.

Comments:
Did this happen after a system update or upgrade? Are you running the original hard drive?
To add to @mayer 's Q's Is this a Fusion Drive config or two independent drives internally?
Is Macintosh HD your Boot drive or is Govind?
it happened after it failed to start and I switched on/off a few times. i ran OS on an external drive and checked the internal drive using disk utility.
Macintosh HD was the boot drive. not since it is corrupt it is not booting.
Govind and Macintosh HD are volumes on the single phydical drive.
Machine doesn't boot. You experience strange crashes. Gets wrong results. Your harddrive is five or more years old. Time to consider repacing it. You do have backup?

Verify a disk
As an alternative, you can verify that the filesystem on the disk is correct. You will not be able to repair the file system.
I suggest that you use disk utility to verify that your startup disk is OK.
Macintosh-HD -> Applications -> Utilities -> Disk Utility
Start up disk utility. On the left pane view, you will see a list of all your disks.
Click on your startup disk.
Click on the First Aid Tab.
Click on verify.

Hopefully your disk will verify. If not, you have to boot from your installation DVD and run Disk Utility from there to attempt to repair your file-system.
