I'm running 12.04LTS.
So I asked this same question on the ubuntuforums and was recommended to get a new drive. I've done that and still have the same problem. Here's the original (http://ubuntuforums.org/showthread.php?p=11981491):
Hi there. So, let me preface this by saying that the drive in question was working. I used it to install 11.10 before upgrading to 12.04. I also used it to install the Win7 dual boot partition.
I'm running 12.04 64bit.
The drive is a Samsung SH-222. I can no longer access the drive in Windows or Ubuntu and I can't even use bootable CD/DVD even though it appears in my BIOS launch options. The drive is receiving power and opens, but if a disc is loaded I get no response (in either OS).
Here's fstab - Quote:

My main HDD is also SATA and is being read fine. I'm at a loss of why this is happening, not just in Ubuntu, but system wide.
Help would be greatly appreciated. This may have happened a week ago or a month ago, I'm really not sure. I so rarely use the DVD drive that I haven't had any reason to try, so I can't really pinpoint where/when it stopped working, sorry. If you need any additional information, I'll be more than happy to give it.
Thanks in advance.
So now, I have installed a brand new drive (same make/model) and am having the same outcome.
