So far, it seems to be harmless. I have: Aopen AX6BC (i440BX chipset) PII-450 128MB PC100 Maxtor 90650U2 Western Digital AC24300L I don't think I have seen the problem on the Maxtor drive (ad0) yet, but I have on the WD (ad1, which contains NT4 and is used by VMWare). ad0: 6149MB [12495/16/63] at ata0-master using UDMA33 ad1: 4112MB [8912/15/63] at ata0-slave using UDMA33 ad1: UDMA ICRC WRITE ERROR blk# 1272570 retrying ad1: UDMA ICRC WRITE ERROR blk# 1272378 retrying ad1: UDMA ICRC WRITE ERROR blk# 1287866 retrying The above errors didn't all happen at once, they were rather spread out. I have not yet scrubbed the WD drive with the factory utils to check for media surface errors, but that could possibly be the problem. -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet.
