Hi,
I remember, I was facing the similar problem long back while taking BACKUP on to the LD disk having smaller cluster factor.
I tested the BACKUP to reproduce the problem by taking the image BACKUP of the disk containing the smaller cluster factor to the disk containing the larger cluster factor and vice versa. But I am unable to reproduce it. I tested this on V8.3-1h1 IA64. Below is the test log.
