I am having issues getting a brand new WD Gold 12TB drive to work in my Windows 10 Pro computer which has a decently recent motherboard (MSI X570 Gaming Plus, flashed latest BIOS). The disk is recognized no problem in the BIOS and in Windows, including with the WD Dashboard tool. Correct capacity and everything. However, when I go to Disk Management, it already was showing a 2TB partition and a 9TB partition. Besides initializing with GPT, I could then not do anything else in Disk Management, everything was greyed out. So I tried a couple of different partitioning softwares and they would always either fail or complete, but not actually do anything. I tried diskpart and had similar results, but it would say i/o error. I ran SMART and it was fine. In looking around, I read about the new issue with "Power Disable" on the SATA power connectors, but this doesn't seem to apply because my disk was powering on no problem and recognized (I tried the molex adapter trick, and there was no change).
I decided to take it to work and pop it in our "enterprise grade" server running Windows Server 2022 and using diskpart, I was able to set GPT, clean it, and create a 12TB NTFS partition right away. I set if offline, removed it, and brought it home, but Disk Mangement immediately was showing the 2TB/9TB thing, and the partitioning software was able to read the drive label I had added, but it would not let me set a drive letter (however, it was showing the 12TB partition properly in the partition software). Tried a few more things, but clearly there is some incompatibility here, or I'm hitting a limit in Win 10 Pro?
Any suggestions would be greatly appreciated, thanks!
