Samsung X5 SDD not found on MacBook Pro on 2.6 GHz Intel Core i7 (2016)

Hi there,

I have recently purchased a Samsung X5 to use on my MacBook Pro, a 2016 Intel Core i7.

I am operating Mojave 10.14.6. The SSD software is saying that no SSD is connected. I can not see the SSD in Disk Utility or anywhere else. I have tried restarting in recovery mode (holding command + R on Start up) however once in the startup Security Utility I don't see the option to reduce the security which I gather would allow the Samsung drive to be accessible. I only see option to "Turn on firmware password". When starting up whilst holding down the option key, only my apple drive is viewable and there is no EFI drive. Maybe I should update to Monterrey?

Thanks so much for any help!

MacBook Pro 15″, macOS 10.14

Occasionally, the cords shipped in the box with devices end up being "lowest bidder" cables, and are sometimes not quite up to the task at at hand.

I suggest that one debugging path might be to acquire a premium-quality cable to try. Rather than a USB-C cable, a Genuine ThunderBolt cable with the same 40GB/sec specs (length limited to a half meter or less) may provide superior results.

Hi Grant,

Thank you for your reply. I am connecting the Samsung X5 device using the thunderbolt 3 (40Gbps) USB-C cord provided. The white LED on the device is illuminated which suggests it's getting power from the MacBook Pro itself.

Thank you,

Hi Grant,

Thank you. I'll give this a try! Any suggestions on why when restarting in recovery mode (holding command + R on start up) and once in the startup Security Utility I don't see the option to reduce the security which should allow the Samsung drive to be accessible? and only the "Turn on firmware password" is present?

Thanks,

Hi Grant,

I bought a new thunderbolt cord and am still experiencing the same problem. The light on the device is illuminated so it's receiving power. It is still not visible in disk utility. Very Odd.
