But....why the change in SATA ports?
I can think of 2 reasons:
- Neatness. E.g OS drive in SATA_0 port, data drive in SATA_1 port. While currently, they could be in random SATA ports. (Might be to do with cable management neatness as well.)
- Possible NVMe in the future. On many MoBos, NVMe drive(s) will disable two SATA ports once installed. If OP has their SATA drive in one of those ports and in the future, when OP looks towards NVMe drive, they may run into this minor issue, where in use SATA port gets disabled.
Shouldnt you delete all partitions on the drive before being able to change the drive letter ?
