Not working after reboot

[Spear]

I was running hashcat using command
"hashcat -m 2500 /root/file.hccapx /root/rockyou.txt"

and it was running properly when suddenly there was a powercut and now after the power came back i tried running the same

but now it gives me an error "Cannot read /root/.hashcat/sessions/hashcat.pid". i tried changing the hccapx file's name but still the same error. Kindly guide me to the solution.
Thanks

you shouldn't run hashcat (or almost any software) as root. Sounds like your file system got damaged, time for a fsck

I am new to linux and so i didn't know the use of fsck command. so i checked on internet about its use and it says there to use it on unmounted partition. I am using The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) linux in dual boot with windows 10, can you tell me how to perform the steps to this command in order to not damage my data while doing so. I used the command "sudo fdisk -l"

and it shows me this list, can you please list the commands to input now to unmount the partition that is damaged and use fsck command on that.
Thanks

Your file system is not the problem. Just delete the hashcat.pid file and it will work again.

Yayy, this solved my problem. Thanks mate. Kudos to you. (I was in the grub menu making my system read only to use fsck when I received your answer). You saved me from a lot of hassle.
