Ubuntu – GParted does not recognize SATA M2

dual-boothard drivepartitioningssduefi

I bought myself a new Laptop, the ASUS GL771JW with 250 GB M2 SSD drive and a 1 TB HDD.

Now I'd like to install Ubuntu 15.10 on it, but I get errors.

I downloaded the amd64 Ubuntu ISO and put it on a USB stick using sudo dd if=/home/myuser/ubuntu-15.10-desktop-amd64.iso of=/dev/sdd. Then I load the Live OS with Unity on it and start GParted, right away getting the error message:

Libparted Warning

The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes.

Cancel / Ignore

If I hit Cancel GParted only shows an unallocated 7.41 GB drive on /dev/sda which is my USB stick. I can as well select /dev/sdb which is my 1 TB HDD drive, but I cannot select my 250 GB M2 SSD drive.

If I hit Ignore GParted shows 4 partitions on a 29.65 GB drive on /dev/sda:

  • /dev/sda1, FS unknown, size 4 KB
  • unallocated, FS unallocated, size 1.09 GB
  • /dev/sda2, FS fat16, size 2.22 MB
  • unallocated, FS unallocated, size 28.56 GB

I have no idea where it gets that from and I miss the rest of the 250 GB drive.

Does anyone know that problem? I tried to find some useful settings within the ASUS BIOS / UEFI-BIOS, but wasn't too successful with it. What must I do to install Ubuntu on my laptop?

Best Answer

I had the same trouble with an NVMe disk. That technology is quite recent and the old version of GParted in Ubuntu repo couldn't see my SSD. I resolved creating a GParted live USB with the latest version of the software.
