Up squared not able to detect 256G ssd (ubuntu 16.04)

Cmqing

I am using a up squared that has BIOS updated to 4.0.
Ubuntu 16.04 installed using the instruction at: https://wiki.up-community.org/Ubuntu
SSD is the one bought in UP shop: https://up-shop.org/up-peripherals/174-msata-256gb-sata.html
However after installing everything, the SSD is not detected in the disk:

Really appreciate any help!

The image in itself does not reveal any clues about the ssd. It only suggests that you have installed Ubuntu on the mmc, the 64 GB storage device that came with your UP2. What does df -h say? Do you see any other devices listed in the GParted menu "Devices" ?

Thanks for the help. No, I cannot see other devices in the gparted device list:

df -h gives the following output(which does not show the 256g ssd):
Filesystem Size Used Avail Use% Mounted on

Did you check

• BIOS settings for the SATA controller
• the SSD is OK (works with some other board)
• the cable connectors for SSD on UP2 SATA port and power are OK
• UP2 power for your SSD is sufficient (larger SSD might need external power supply)

If all that checks out OK and the SSD is still not detected by the OS, you might need to look into kernel message logs for errors. However, if you don't find any problem with the above questions (and your Ubuntu install runs just fine otherwise) then I can't see why there should be any kernel issues with respect to the SSD.
