I just used the "Drive Fitness Test" for IBM ATA drives on a particular disk and it finished without detecting errors. However, I see messages like this: Apr 16 22:51:44 seth kernel: ad3: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=1904935 Apr 16 22:52:02 seth kernel: ad3: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=8029031 Apr 16 23:35:30 seth kernel: ad3: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=2269287 Apr 16 23:37:22 seth kernel: ad3: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=3612007 Apr 16 23:48:17 seth kernel: ad3: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=1932123 Apr 17 21:12:25 seth kernel: ad3: FAILURE - SMART status=51 error=4 LBA=12734209 Apr 17 21:12:25 seth kernel: ad3: FAILURE - SMART status=51 error=4 LBA=12734214 in /var/log/messages. Do the kernel messages indicate a potential problem with this drive? Whom should I believe, FreeBSD or the disk diagnostics tool? -- Regards, Doug
