Hi, I’ve researched this this issues quite extensively, and I’m coming up short with solutions. I want to use the drive as an external backup. I’ve formatted the drive as GPT, I’ve checked that my BIOS is UEFI enabled, and the drive still shows as only 1.5 TB. Any other ideas? Thank you.
Does it show the correct capacity within Disk Management when connected internally as a secondary hard drive? If so, check the external enclosure you are using. It may not support 6TB hard drives.
