The "WRITE_DMA" failure is occurring any time I have both channels on the second SATA adapter running, and is random. It appears to be linked to read/write activity, but not "mostly write" or "mostly read", as I can reattach both disks to the mirror, and they will rebuild without drama - but once they activate, then the problems begin anew. This occurs on both an Adaptec and Bustek SATA adapters. Ideas? Should I "send-pr" this one? -- -- Karl Denninger (karl@denninger.net) Internet Consultant & Kids Rights Activist http://www.denninger.net My home on the net - links to everything I do! http://scubaforum.org Your UNCENSORED place to talk about DIVING! http://www.spamcuda.net SPAM FREE mailboxes - FREE FOR A LIMITED TIME! http://genesis3.blogspot.com Musings Of A Sentient Mind
