Q: What can I do to fix “WARNING - READ_DMA”
errors that show up in the log?
A: Hardware issue
Check cables (IDE, SATA, PATA) and connectors.
Check disks. Review S.M.A.R.T. reports for errors or warnings and run disk manufacturers' diagnostic software to make sure the disk is not damaged.
Check disk controllers. Make sure all MotherBoard BIOS settings are correct if you are using an onboard controller. If you are using an add-on controller, make sure it is configured correctly. If it is a SIL chip-set based controller, please read –dead link {Controller with Silicon Image Chips} –.
