How do I recover from a read DMA bootup error?

There was an Input Output error at your Hard Disk sda part, at sector 4650928. You can boot from Ubuntu Live cd/dvd/usb, start Disks Utility, try to see the SMART data and test your sda disk.

The DMA read error was real. There was indeed a bad sector and replacing the SATA cables did not help. I finally tried to re-install from LiveCD, and the installation failed due to my bad disk drive. I originally went with an SSD because I wanted fast bootup, and was told that the Corsair Nova 2 was a good one, although more recent reviews (and this experience) refute that.

So the answer to this question should be marked as being due to a failed solid state drive.


I encountered a similar problem today. I unpluged sata cable and reconnected my hard drive to motherboard and it worked !
