Re: Disk Utility to align tracks on a hardware RAID1 system

Hi Jenny, thanks for the info
I was not specific enough in my last response.
I wanted to know if after removing the partitions & rebooting the system
with some sort of system disk. Running the utility: what is the command
options syntax as well as what offset do I choose - that part in the
instructions are vague.
Thanks
Kevan
