Google found that temperature does not really affect reliability much except only slightly in extreme cases: http://labs.google.com/papers/disk_failures.pdf Robin Harris has a good summary here: http://storagemojo.com/2007/02/19/googles-disk-failure-experience/ So that might not help much. If you want to replace the drives I would look at the specs provided by the manufacturer. Does it specify an ambient environment temp range? Maybe you exceeded that. Here is another good hard drive study: http://www.cs.cmu.edu/~bianca/fast07.pdf These seem to be the two most cited/useful. -- Tracy Reed http://tracyreed.org This email has an attached digital signature.
