Usb Hd problems [SOLVED!]

Hi guys,

I'm trying to leave the n00b status behind, and switch my distro from Ubuntu to Arch recently. I really love this distro, but the things are quite hard here. hmm  Right now I'm trying to mount a external/USB hd without sucess. This HD is working, I test it at my university, in a Debian machine.
I try a pen drive at the same usb port and it mount without problem.
Any help or advice will be appreciated. smile Some code follows:


lsusb before plug it:

Bus 002 Device 001: ID 1d6b:0001  
Bus 001 Device 001: ID 1d6b:0002

lsusb after plug it:

Bus 002 Device 001: ID 1d6b:0001  
Bus 001 Device 012: ID 13fd:160e  
Bus 001 Device 001: ID 1d6b:0002

He dont appears in fdisk -l (it has 160GB):

Re: Usb Hd problems [SOLVED!]

Guys forget about it!

I boot my machine and try to mount in Windows. And the HD does not mount!!!
So I remember that once I have a problem with "low voltage" usb ports with a cellphone. Once this HD does not have a power supply I try the back USB port and... IT WORKS! big_smile
