First of all I hope @klanomath is still active over here as I'm having a similar issue as described in following thread: Partition on HFS+ external drive: "Invalid number of allocation blocks", file system check exit code 8. Unable to repair, even in recovery mode . However it's slightly different.
I'm having the "invalid number of allocation blocks" error on my main hard drive (startup disk).
As it looks like the solution for this issue was "tailor-made" for the problem of the initial poster I'd like to ask if you could adapt the solution for my case.
Which info would you need and would you be able to repair the disk so no data would be lost. I've been hard at work just before my crash and it would take a lot of time to do it all again. Sadly my NAS wasn't available at the time for a Time Machine backup...
I also checked this HFS+ invalid number of allocation blocks but I don't really understand what's going on there and I don't want to do anything wrong.
Let's hope someone can help me!
Thanks in advance!
Kindest regards,
Kim

diskutil listanddf. These commands will not change your computer. You will need to enter the commands in a Terminal application window. Edit your question and paste the output. Don't worry about the format, someone else edit your question and fix this. – David Anderson Feb 07 '19 at 22:49
