I have three 1TB disks I use for backup, two of them are Western Digital drives I bought specifically for this purpose. One is a Seagate drive that came out of a barebones PC that I replaced with a couple smaller drives in a stripe to gain performance. I use the drives in an external SATA dock, using geom eli encryption, the western digital drives give me no problems, but the seagate drive gives me a lot of the following errors under load. ad4: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=817755328 ad4: WARNING - WRITE_DMA48 UDMA ICRC error (retrying request) LBA=837397120 ad4: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=879786112 ad4: WARNING - WRITE_DMA48 UDMA ICRC error (retrying request) LBA=882931200 ad4: WARNING - WRITE_DMA48 UDMA ICRC error (retrying request) LBA=890542016 ad4: WARNING - WRITE_DMA48 UDMA ICRC error (retrying request) LBA=902767296 ad4: TIMEOUT - WRITE_DMA48 retrying (1 retry left) LBA=904071296 dmesg info about the drive at connection time: ad4: 953869MB at ata2-master UDMA100 SATA 3Gb/s dmesg info about one of the western digital drives: ad4: 953869MB at ata2-master UDMA100 SATA 3Gb/s Before I scrap the drive I just wanted to see if anyone could either say for sure its hardware, or if something else could possibly cause this. I don't suspect the controller, cable or dock as the problems would likely occur with the western Digital drives as well if one of them were involved. -- Thanks, Dean E. Weimer http://www.dweimer.net/
