Hi, Thank you very much for the help.
Actually for testing the speed of USB external drive, hdparm command works fine. I was just wondering if there are any set of USB-utilities for linux which gives all kinds of information about the USB devices attach to your system also which has a benchmarking facility.
Any help will be appreciated. Kushal Koolwal

Isn't that exactly what you should expect? hdparm does the timing test, which is what you asked about originally. The information retrieval involves sending ATA commands over a non-ATA transport, so of course it won't work. Alan Stern
