Hi ! Thank you all for your prompt replies. You have said in your replies that the bs parameter should be set appropriately. Is there a way to find out appropriate block size, or any reasonable size should do, like 1k or 4k. I am asking because I tried it a few weeks ago and I was unable to mount the new drive let alone boot from it. Mostly I must have done something wrong. I dont have access to another drive or else I could have tried it again. Let me know if any block size will do or should it be specific. Thanks -Pranav ******************************************************************* Pranav A.
