I have two sata hard disk installed in my desktop. When i try to install ubuntu in /dev/sda it shows an error at the end of installation process. Error: "I/O or faulty hard disk or faulty medium" something like this.
I tried to install with several ubuntu cd/dvd, all shows the same error. I have successfully installed fedora on the same partition. I tried to read other DVD/CD to check that my DVD drive is ok.
I found that i have no problem in DVD drive, installation CD/DVD. Now problem is hard disk. Fedora does not show any error or warning about hard disk. And here is the partition table of my HDD:

I can not figure out what the actual problem. Please help. Thanks in advance.
