"vbr read failed" on Mac

[anjandash]

I'm trying out your tool on my mac for a hard drive which often gets disconnected easily.
And it takes forever to do the fsck check.

I used your tool, and it gave me the following error: "vbr read failed"
I couldn't figure out the problem here as I am not proficient in C++.

What could be the isssue here?

$ ./exfat_clean /dev/rdisk2s2/
vbr read failed

You will need to run it as root.

Hi thanks for raising up the problem. I tried as you said but when I type $ sudo ./exfat_clean /dev/rdisk2s2/ i stil receive the reply vbr read failed. Is there anything else that I should be doing?
