I have a tar of my packages and am basically untaring the file .. the tar file is in the device so I have a copy of the pkg.tgz in SSD as well as PCIe and and im untaring it locally.. so source and destination is same disk.. I have untared it numerous times and got the same result. Is there anything setting in netbsd that I forgot to enable.
