I used an IBM DeskStar drive and had Linux running perfectly well on it. I backed up all my data, deleted the partitions and went to install FreeBSD on it. The installation failed with lots of 'hard error' messages. Did FreeBSD kill my hard drive, or was it just luck that I got my data off the drive with minutes to spare? I know DeskStar drives are notorious for failure, but I did indeed have DMA66 and DMA33 drives on the same channel, and thought it a bit suspicious that the drive died at the instant I tried to install FreeBSD.
