How to set Samsung drive "Jumper" to Master, Slave or Cable Select?

1. Upper 32GB (capacity ≥32GB)
Because some BIOS has 32GB capacity barrier, Jumper setting is different.

There are two cases.

• Having no 32GB capacity barrier ; General.
• Having the 32GB capacity barrier.

If you set the jumper with the capacity limitation upper 32GB, the system recognizes the capacity as 32GB whatever the HDD’s capacity.

If your system has the 32GB barrier, you can solve it with using the DiskManager.

Same as below but the jumper is located in between Power and Data connectors.
