Hi Tejun,
Thanks for your pointers, I got sidetracked yesterday with other
work.... The problem is reproducible by doing a simple 'dd' to create a
multiple GB file. The error occurs on different drives at the moment.
I am on vacation for the next week but I will remove the linux Raid
array and test the drives individually (hopefully today, but maybe when
I get back from vacation) and report back to you then...
