Does anyone have any ideas on what would be wrong with a drive that functions perfectly when turned on, but as it heats up, almost everything goes sour? 30 meg CMI RLL in a fan cooled case next to a 60 meg Hitachi. Thanks for any info. -- Greg

Just like everything else, the parts in your HD expand as they heat up, and this can cause horrible alignment problems. What you should probably do is back up everything on the disk, then let it run for a couple of hours, then do a low-level format, high-level format, and restore everything. That should take care of the problem. Brendt decomyn@penguin.uss.tek.com "The organization disavows all knowledge of my actions."

Never had any problem since then. Overheating problems are common. Don't place a hot drive under an another drive. Place the hotest drive highest and cooler drives under. The problem is that it's not enough space between the drives and even if the fan is good, the air don't reach the sensitive components and they can easily be overheated. Replacing the drives can often solve overheating problems.
