DVD rip Error. Help?

Hello!
MKV has worked excellently so far with the exception of a few of my discs. I am thinking this is not due to the DVD reader (USB reader which is hooked up to my laptop), but maybe due to the disc. This is the message I receive:

Error 'OS error - STATUS_DEVICE_DATA_ERROR' occurred while reading '\Device\CdRom0' at offset '18432'
