Force Logical Block size for HDD pulled from external enclourse

So I pulled a 3tb hitachi drive from an external enclourse, and the usb-to-sata board in the enclourse forced a logical sector size of 4K for the drive. But connecting directly to the drive exposes the logical sector size to 512 bytes. Resulting in me being unable to mount the partition. So what I am asking is, is there a way to force the logical sector size for a drive to be different than the drive exposes or am I going to have to move everything off the drive and reformat it?

The enclourse in question:
