Hello All,

My $SUBJECTS_DIR is located on an external disk that was mounted and
recon-all exited with errors at ln -s lh.white.preaparc.H lh.white.H
I was not able to perform this operation with sudo as well

4172_vsl/surf$ sudo ln -s lh.white.preaparc.H lh.white.H
ln: failed to create symbolic link 'lh.white.H': Operation not supported

but cp works
4172_vsl/surf$ cp lh.white.preaparc.H lh.white.H

has any one come across this problem and what is the best way to fix this?

Thanks,
Pradeep
