I get a message saying one of your hard disks has reported failure, sometimes. But I check HD Tune Pro's health section, and the only error I can see is "Ultra DMA CRC Error Count" which has been at 195 since I can remember. (ie. That hasn't increased for years.) Yet I keep getting this message sometimes from Windows. The HDD in question is a Samsung HD502HJ 500GB. Any idea why this message is popping up? Thanks.
