I installed FreeBSD on a Maxtor 300GB IDE drive that is less than 1 year old. After one day, FreeBSD complains about DMA problems. I got a LOT of these. ERROR MESSAGE: kernel: ad0: FAILURE - READ_DMA status=51 error=40 I googled for the error, and foudn a suggestion that the drive may be failing. So I ran Maxtor disk diagnostics and it says the drive is failing. So I start the RMA process. In the meantime, I install a BRAND NEW Seagate 120GB 7200.7 hard drive. I install FreeBSD 5.3 on it. One day later, I get the SAME errors! Lots of em! kernel: ad0: FAILURE - READ_DMA status=51 error=40 What is going on? Is FreeBSD destroying my disks?
