Free space partition

[aminul001]

So I created a partition for the windows . And then decided to delete the partition.

But when I was removing the partition from the disk utilities accidentally I plugged out my mac charger and my mac shut down.

After turning on my mac I saw that my main disk is 92gb used and 154 gb available.

But my disk is about 600gb .

I created a partition about 354 gb.Then I goto partition again to check what happened to my other disk.

And saw this.
Free space partition and the format is also free space.
Whatever ever I tried to remove this partition but its failed every time.

I also run the command "diskutil list" To see what disk is this Free space partition. But it didn't shown.

Please tell me how can I repaire my hard disk. Is my hard disk damaged or can't be fixed
Please help me. What to do to remove this free space partition.

When you lost power, that likely corrupted some part of the drive. diskutil list does not show a partition, just that there is more space on the drive than you have in partitions.
If you have tried to change the partition setup, so that free space is usuable, and it errors out each time -- I would suggest wiping the drive and starting over.
Does it boot to the Mac system without problems? If yes, then I suggest that you do a full backup (if you don't already have one), then boot to an external installer. If you have one for High Sierra, that would be ideal. While booted to that macOS installer, open Disk Utility. You could try one more time to remove that free space partition, as you are not booted to the internal boot drive, and the re-partition might work this time. If so, you might not not need to do anything else (the drive would now work with the full drive space again), but if it fails again, choose the drive from the list on the main window in Disk Utility. Should be the line "Intel SSDSD2CW600G3 Media". Name it something you might like (otherwise it defaults to "untitled", which is no name at all, IMHO. )
When you have the drive successfully erased, Quit Disk Utility, then continue on with a reinstall of macOS. The installer for High Sierra will take care getting the SSD properly formatted for APFS, and you can recover your files and other apps from your backup, if you need to do that.

Hey I have 8gb usb . Can I backup only my mac os in the usb with the help of time machine. And then reinstall the os from recovery option using time machine.

Reinstalling mac os is not possible for me now.. Is there any way to get a backup of my mac os... And can I use my 8gb usb for that?

If you have High Sierra, then the full installer will easily fit on an 8GB USB drive, as it is less then 5.5 GB.

There is probably a method to backup just the system (I have not looked for that, the downloaded installers are what I keep) -- but I checked on a drive where I have just the basic High Sierra install. The installed system and library files are near 12GB, and that does not include the various hidden files installed with the system, which are around 3GB for a system with nothing else added. So, from what I see, the various parts that get installed add up to around 15 GB, and I don't think there is a way to back up just the system files, from an installed system drive. Again, that's a reason to keep the downloaded installer app. You can always use that installer app to make a bootable installer later, when you need it...

So, are you saying that you cannot download the full installer?

Finally, the important part is downloading the full installer. There's no reason you have to continue with the install immediately. In fact, the installer will automatically launch after the download. You don't let it continue, but Quit the installer, save it to an external drive. Then, you can choose when to make the bootable installer from that downloaded installer app. It's all part of the fun! And, the bootable installer for High Sierra easily fits on your 8 GB USB drive

My answer (post #2) above should be helpful to you for a reinstall
