I am having a strange problem and need some help. 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<READY,DSC,ERROR>
error=40<UNCORRECTABLE>
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<READY,DSC,ERROR>
error=40<UNCORRECTABLE>
What is going on? Is FreeBSD destroying my disks? Here is some info:
