Hello, I have 2 drives Netapp Hitachi 10TB drives that are formated to 520B. THe model numbers are X377_STATE10TA07 I am using sg_Utils to format them back to 512B. Both disks are not finishing the reformat process. 1st disk stops at Format Unit Complete at 2.61% 2nd disk stops at Format Unit Complete at 83.15% I have tried multiple times with the same issue and stops around at the same percentage. What could be the problem?
