This is not normal and usually points to bad drive or buggy firmware. Have you had a look at smartdata for the drive(s)? (you may want to run the smart selftests) Also, I'd suggest you test it in a controlled environment. For example, can any of your drives survive a full surface write? (dd if=/dev/zero bs=1M of=..) Full surface read? Do the tests against /dev/sdX to be sure (excludes partitioning, filesystems, volume management, etc.) Do note that writing your drive full of zeros _will_ destroy your data (I really hope that's stating the obvious...). /Peter
