I have WD green hdd (4TB logical512/physical4096) inside wndr4700, with ext4 filesystem, the filesystem works good with computer, but when i use with wndr4700 it has few error, such as when i do "ls -l" it take too much time, copying to hdd over wifi halts after few sec or min.
WIFI/WLAN Electromagnetic interference can confuse and damage the HDD
Due to the close proximity between the hard drive, the WIFI and the antennas, the electromagnetic interference of the WIFI can confuse and damage the HDD. If you hear a clicking noise once any of the wifi chips is enabled, you should immediately limit the tx power. This may not effect everyone, because some Regulatory Bodies limit the tx power by law. So check if you have set the right country code/regdomain too.
