This desktop has an internal SATA hdd (/dev/sdb/) with bad sectors on one partition. I've purchased a Seagate FireCuda 4T SATA hdd to replace it.
Connected a USB3.0 adapter (powered by a wall wart) to the drive, and the drive to a USB3.1 port on the front of the case and turned it on. fdisk -l recognizes the two internal and 4 external drives (/dev/sda/ through /dev/sdf/) but not the new drive. I don't recall this happening in the past with an external naked hard drive. What might I be missing? TIA, Rich
