Ed makes the point that the USB host may not handle powering the drive and the WiFi, very well, simultaneously. I'll make the point that some externally power supplies are absolutely terrible, they can radiate a massive amount of electromagnetic interference. I've had a couple that could knock an ADSL modem off-line if I plugged them into a computer, anywhere on the network, even in a different room. The drive just had to be connected, the system it was plugged into could be completely powered off. It just spewed crap everywhere. The modem would die off and stay unworkable. For what it's worth, for anyone else dealing with this issue, the wall-warts are better than the small brick in the middle of a cable, power supplies. I haven't had the wall-wart power supply interfere with anything, even if they're a switchmode power supply. -- tim@localhost ~]$ uname -rsvp Linux 3.19.8-100.fc20.i686 #1 SMP Tue May 12 17:42:35 UTC 2015 i686 All mail to my mailbox is automatically deleted, there is no point trying to privately email me, I will only read messages posted to the public lists.
