Is module 0B in rom contains the directory location ? I compared module 0B on both drives and it was identical so it means the directory location are the same .
So the main question remains, is wd smart hot swap is possible when ROM firmware number a little different at the end like this patient:WD7500BPVT-80HZT3 firmware 01.01A01 ROM firmware 0065000U
donor: WD7500BPVT-80HZT3 firmware 01.01A01 ROM firmware 00650018 ?
