My new laptop is a Dell vostro 5510 i5. It uses 2 NVMe drives - I have only used SATA until now.
I've successfully loaded UM 22.04 LTS to it's smaller drive and used a gpt partition table on the 2tb drive with 5 EXT4 partitions.
When I copied my working data from the desktop PC [also running UM 22,04 LTS, but SATA AND SSD DRIVES] the transferred data did not work and all the partitions on the 2tb DRIVE [NVMe] became UN-mountable.
Does my old data need converting? What am I doing wrong?
Perhaps the new drive is faulty? [can't provide details as the laptop is back with the supplier]
