4TB Drive Only Shows 2TB: Why and How to Solve It Easily? |
[SOLVED] - SOLVED! - 4TB HDD recognized as TB Windows 7 | Tom's Hardware Forum.
Prior to the reimage, Disk 2 was seen and used by windows as a 4TB hard drive. How do I make Windows see the disks for their true size? Thank you. Improve this question. You may have to use a third party software to convert the disk to GPT and create the 4tB volume you desire — Kinnectus. Add a comment. Sorted by: Reset to default.

Start Disk Management If the disk contains any partitions or volumes, right-click each and then click Delete Partition or Delete Volume , until the disk is all one unallocated space.

This article discusses the manner in which Windows supports hard disks that have a storage capacity of more than 2 TB and explains how to initialize and partition disks to maximize space usage. In order for an operating system to fully support storage devices that have capacities that exceed 2 terabytes 2 TB, or 2 trillion bytes , the device must be initialized by using the GUID Partition Table GPT partitioning scheme.
This scheme supports addressing of the full range of storage capacity. It also describes the requirements to address the full storage capability of these devices.
It's the arrangement of the logical sectors that constitute the media. LBA0 represents the first logical sector of the device, and the last LBA designation represents the last logical sector of the device, one label per sector. To determine the capacity of the storage device, you multiply the number of logical sectors within the device by the size of each logical sector. The current size standard is bytes.
For example, to achieve a device that has a capacity of 2 TB, you must have 3,,, byte sectors. However, a computer system requires 32 bits 1 s and 0 s of information to represent this large number. Therefore, any storage capacity that is greater than what can be represented by using 32 bits would require an additional bit. That is, 33 bits. The problem in this computation is that the partitioning scheme that is used by most modern Windows-based computers is MBR master boot record.
This scheme sets a limit of 32 for the number of bits that are available to represent the number of logical sectors. The 2-TB barrier is the result of this bit limitation.
Because the maximum number that can be represented by using 32 bits is 4,,,, it translates to 2. When your hard drive shows the wrong capacity on the computer, you can restore the full capacity by deleting partitions and create new partitions. Back up your data in advance to prevent data loss. Go to Disk Management on your computer. Find and right-click on the hard drive not showing capacity, and select Delete Volume. Right-click on the unallocated space on the hard drive, select the New simple volume to create new partitions as you need.
Follow the on-screen instructions to create new volumes and restore the full capacity.

I also think the overall look and feel of EaseUS Partition Master Free makes whatever you're doing with your computer's partitions easy.
Partition Master Free can Resize, Move, Merge, Migrate, and Copy disks or partitions; convert to local, change label, defragment, check and explore partition; and much more. A premium upgrade adds free tech support and the ability to resize dynamic volumes. It won't hot image your drives or align them, but since it's coupled with a partition manager, it allows you do perform many tasks at once, instead of just cloning drives.
Op: do you update the intel chipset or RST driver? Jun 12, 3 1 15 0. ArmyIsHereWithLemons said:. Hi Thanks for replying. It's weird. General advice for upgrading to larger hard drive: 1 backup important files 2 check your computer mfg website for bios or chipset intel large hard drive support updates. If your bios cannot handle your larger drive size, then it will report a smaller size than the actual size of the drive.
This is very common. On microsoft com you google the partition size limits for your version of windows. Satan-IR Distinguished Ambassador. Apr 18, 2, 21, If you are the thread opener, you have a choice in the top left corner of each post that looks like a Trophy.
