Hi,
We have a Windows 2008 R2 server which has 10 disks. Except C: drive, other disks ae GPT disks. My question is what is the offset size for GPT disk to be properly aligned? When I check in diskpart for C: drive partition, the offset shows 32K. Is it correct? if not, how to fix it? Below is the output. Other partitions on GPT disks shows 129 MB as offset size.
