On my Lime2 RevL with latest olimex kernel I keep getting these errors frequently. The power supply of the board is 15W. I've replaced the SATA cable as in different fora this is suggested to be the cause. The WD 1TB 2.5" disk can be checked on another board and seems to be OK. As the enclosures have ventilation openings around the board it is unlikely caused by overheating.
Are there other Lime2 users experiencing the same disk failures and if so what was your solution?
