Just an aside here, but, a well known disc array manufacturer, IBM,
allows for a 30 minute HD warmup when replacing HD's concurrently. I'm
sure you're aware that heat causes expansion and as the bit density
increases and the track width decreases(more tracks/platter) on the disc
platter thermal stability becomes an issue.
An issue for the drive manufacturer, not the user. Drives
have temp sensing and do account for platter thermal
changes.
