Why can't partition 4TB Seagate hard drive?
Some users find the newly bought 4TB Seagate hard drive and intended to format and partition it in Disk Management. The Windows won’t let him partition the 4TB hard drive, it’s so upsetting. The new disk doesn't have any problem, but why the system can't partition this disk?
Generally speaking, Seagate external hard drives and internal hard drives are shipped with Master Boot Record (MBR) partition scheme by default which supports only 2TB of hard drive space. If you want to use the whole 4TB Seagate hard drive in your computer, you have to convert the 4TB Seagate hard drive from Master Boot Record (MBR) to GUID Partition Table (GPT), and create a partition on it.
GUID Partition Table (GPT) is a newer standard for the layout of the partition table on a physical storage device used on a desktop or laptop computer. It makes you can create a partition larger than 2TB in your hard drive. GPT partition table has many other advantages compared with the MBR partition table, and if you're planning on upgrading to Windows 11, you'll have to choose GPT disk as the system disk.
So, if your 4TB hard drive is an MBR drive, you may stick in these situations:
• 4TB hard drive only shows 2TB;
• 4TB hard drive displays several partitions that are not your expectation;
• The modern Windows system doesn't support the Seagate 4TB hard drive
...
Eventually, the best way to solve these problems is to convert MBR to GPT and create a partition on it.
