Is your usb port supporting the power of the drive? Have you cross checked this drive on other USB ports behind your pc as well as on other machines? I have seen machines that take USB pen drives but cannot take the portable disk. It is the limitation of your motherboard's USB ports.
I think that this external drive is supported only by USB2 ports. Since my present computer/motherboard is old (pentium 4 motherboard), it could be that i am trying the drive with USB1 ports. Is there any way to connect USB2 ports onto this motherboard using a pci card or something similar?
The command lsusb gives me this information on this computer
kussh@desktop:~$ lsusb Bus 005 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub kussh@desktop:~$
which shows that ONE usb2 port controller is present on this computer's motherboard alongwith 4 USB1 ports.
