One single physical HDD shows as 2 separate disks in Disk Management as Disk 1 and Disk 2. I need it to be one C drive disk, so C: Drive will be it's full 8TB and not just 256GB like the previous drive.

How can I correct this to show only 1 Disk/HOW DO I MERGE THEM when it is one drive to begin with??? Since they are separated, no free software will allow this merge. Partition issues. Windows 10.

Please show a screenshot of the Disk management. Run Device manager and show a list of disk drives.

2026-09-13T07:27:13.84+00:00 I went into the bios over a month ago and changed the boot disk to the 8TB HDD (from the orig internal 256GB m.2 that stopped working) .. the laptop cannot see the old drive , so I am not sure why C says what it does in this photo because C is the new 8TB drive, but it's only letting me use the space that was on the orig hard drive.

Could it be that you have one 8 TB HDD and one 256 GB SSD drive with M.2 interface on the motherboard?
