Scenario:
Raspberry model B powered by 1A usb.
Hard drive: 2TB WD20Ears 3.5'' so I use this adaptor from sata to usb: http://dx.com/p/usb-2-0-to-sata-ide-5-c ... 113?item=8 so it's self powered.
The hd is connected to a Powered usb hub: 'Newlink NLUSB2-222P 4 port USB 2.0 Hub with 5V 2A PSU'.
Only for the record: that usb hub is in this list: http://elinux.org/RPi_VerifiedPeripherals
OS: Raspbmc.
Actually everything works fine, the hd is automatically mounted, xbmc detects it etc.
However right after I plug the hd in the hub (or directly to the raspberry, or even if I reboot with the hd already plugged in) the screen becomes blurry, with snow/noise..
Do I need a better usb hub providing more Amps? even when the hd is self powered? Or what do you think is the problem? Thank you very much in advance.
