UPDATE I have tracked down why Dolphin, Kwrite, etc. take so long to open the NTFS 2nd hard drive in my system. This was my iptables setting:iptables -P INPUT DROP iptables -A INPUT -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT iptables -P FORWARD DROP ip6tables -P INPUT DROP ip6tables -P FORWARD DROP ip6tables -P OUTPUT DROP With this firewall setting, the NTFS drive took over 4 minutes to open in a KDE window. I added the loopback rule ofiptables -A INPUT -i lo -j ACCEPTand now it opens instantly. I have no idea why a firewall setting is affecting KDE's ability to open an internal SATA NTFS hard drive, but it is. If I remove the loopback rule or set the OUTPUT rule to DROP, the NTFS slowdown reappears instantly.
