Hello everybody,
I'm a long time user of ubuntu and I just ran into a problem with my laptop. My laptop HDD has become corrupted and I am unable to mount it or read any data from it, but I can see the partition table and the partitions and all that, So I booted into an ubuntu 14.04 live usb with persistence, But the live usb tries to recognize the hard drive for 20 minutes before booting the live usb. It just gives the same error again and again. Here's an excerpt from dmesg

I'm currently posting this from my live usb. What do I do to prevent it from seeing my dead hard disk and trying to read it ? If you need any additional data, Please give me a request.
