I have a Lenovo 3000 G530, with Ubuntu 14.04 installed. This system, used to have Windows 7 Ultimate installed as the OS, and I immediately noticed that the disk drive no longer works, after the installation of Ubuntu. I do not have a dual boot setup, and the only hardware that I have replaced, was the installation of an SSD, in place of the HDD. The disk drive worked, when Windows was installed, and I have used the software and updates feature, to search for any additional drivers, but with no luck. Could someone please help me troubleshoot this issue? This is a X64 system, and I do not see any Linux software, for this model, on the Lenovo website. Any assistance, is much appreciated. Thank you, very much, for your time.
