Can’t see partition device after creating GPT partition on 6TB disk

I have a 6TB disk in Debian Linux 12, let's say the disk is /dev/sdd. It's just for data; no parts of the OS are on it. Now I’m trying to use it as a normal disk with the full space in a single partition. If I try to create the partition, fdisk tells me that the max size with a DOS partition is 2TB. If I create that, I get a new device /dev/sdd1, but the size is limited to 2TB, not what I want. To have a single 6TB partition, I need to use a GPT partition table instead of DOS. If I do that, I can create a single partition with fdisk. But then I don’t get a device node for the partition (/dev/sdd1), which I need later for things like formatting. Any ideas? **EDIT** I create the partition that way. fdisk /dev/sdd Tells me then: *The size of this disk is 6 TiB (6597069766656 bytes). DOS partition table format cannot be used on drives for volumes larger than 2199023255040 bytes for 512-byte sectors. Use GUID partition table format (GPT).* Commands are then: g n w That creates a GPT partition table and a new partition with full size and writes it down.
