Unquoted text below is from either me or from my friend. Someone suggested we try an older kernel as if kernel 2.6.32 would not have this problem. We do NOT think it suddenly started with a certain kernel version. I was just hoping to have you kernel-guys help with prodding the kernel into revealing which component was screwing things up....

Yes I did. The disks were installed in a MSI/Core2DUO based desktop system. No problems at all. Transfer rates up to 200MB/s. The SIL 3114 chip is 1.5Gbps SATA. . Searching for information on the WD drives I stumbled across: http://community.wdc.com/t5/Other-Internal-Drives/1-TB-WD10EARS-desynch-issues-in-RAID... Where it seems that WD simply says not to use these drives in a RAID. I have experience with "Raid Edition" drives: They go bad at a MUCH too high rate. If we can't use the non-raid for a RAID application, then there is just ONE possible option: STAY AWAY FROM WESTERN DIGITAL: Western digital claims it has the right to mess things up if you put a non-raid drive in a raid configuration. Well fine. Then they can also mess things up in normal situations because when Linux does software raid there isn't any difference from RAID accesses. (if you click through and read their entry in the knowledge base, you'd notice that it should be more or less the other way around. Linux will drop the RAID-enabled drive from the RAID within seven seconds and reporting error on a sector, whereas the desktop drive would remain operational until Linux times out (30 seconds?))
