According to:


LBA 48 was required to get beyond 128 GiB,   The limitation in the IBM SATA 
controller must have been something else.  

It would be useful for others on the list to know what  caused the limit.  A  
likely suspect  is SATA spec.   Would you please check what SATA level the two 
controllers support.
