I encountered a problem while trying to upgrade an old (10+ years) Samsung NP300E7A-S01IT laptop's HDD into a newer SSD.
I bought the SSD (Samsung 870 EVO 1TB 2,5" SATA III SSD MZ-77E1T0B/EU) and cloned the HDD (Hitachi 640GB 2,5'' SATA II HDD NP300E7A-S01|T ) into the SSD. But when I installed it onto the laptop, the BIOS wouldn't see the hard drive (wouldn't be listed in the bootable devices and the SATA slot was listed as empty).
The laptop is a Samsung notebook model NP300E7A running Windows 10 Pro.
What I tried to do:
- Resolve boot problems with the Windows 10 installation media.
- Hook the cloned SSD to a USB to SATA connector. The laptop booted into Win10 but then Windows showed an error "Device inaccessible"
- Formatted and cloned the SSD again.
- Changed the cloned SSD from MBR to GPT and vice versa.
- Checked for driver updates
- Checked if the SSD is faulty. The SSD seems perfectly Healthy
- Forced AHCI on
- Switched back to the old HDD and back again to the new cloned SSD. The laptop booted normally with the HDD, but the problem persisted on the SSD
I suspect the problem may lie onto the connector since the SATA connector lacks some pins as you can see in the first picture below.
