I have an SSD with a C drive of 56 GB and D drive of 53 GB. However, in Disk Management there is an OEM Partition between the two. I am not looking to remove the OEM Partition. I just wasn't able to transfer 1 GB of space to D Drive.
However, even though I can shrink C drive, I cant Extend D Drive (it is greyed out)
It looks like this:
C Unallocated Oem D 56.19GB 1GB 868MB 53.2GB
I want to extend the D drive. There is an unallocated space of 1 GiB. The extend volume button is greyed out.
