Even though the drive may not be visible on the "Desktop" or in "My Computer," check to see if the drive is recognized in "Disk Management. It is an Internal HD. No error messages. So far I have tried: Checking connections. Reinstalling Win 7 64, Attempted to reformat it with disk management but as it doesn't show I cant do this as per other suggestions found in these and other forums.
Things I have yet to try: Unplugging my Primary HD and installing Win7 32 on the 2TB hd currently my secondary then plugging everything back up and installing Win7 64 again on the primary HD suggested on an other forum Any help would be appriciated.

Regards, Divya R — Microsoft Support. How satisfied are you with this reply? 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. Therefore, a capacity beyond 2. To make more bits available for addressing, the storage device must be initialized by using GPT.
This partitioning scheme lets up to 64 bits of information be used within logical sectors. It translates to a theoretical limitation of 9. By default, many current systems can support UEFI. Microsoft expects that most future systems will have this support.
Customers should consult with their system vendor to determine the ability of their systems to support UEFI and disks that have storage capacities that are greater than 2 TB.
For a system to be able to address the maximum capacity of a device that has a storage capacity of more than 2 TB, the following prerequisites apply:. The Windows version must be one of the following bit or bit, unless otherwise noted, but including all SKU editions :. The latest storage drivers from your storage controller manufacturer must be installed. For example, if your system uses an Intel storage controller that is set to "RAID" mode, make sure that you have the latest applicable drivers from the Intel support site.
Overall, you should contact your system vendor to determine whether the system supports device sizes of more than 2 TB. For example, if your system uses an Intel storage controller set to RAID mode, make sure that you have the latest applicable drivers from the Intel support site.
Consult your system vendor to determine whether the system supports both UEFI and the startup of devices that have storage capacities of greater than 2 TB. The following tables list Microsoft support for the various concepts that are discussed in this article.
This information provides an overall support statement about disks that have a storage capacity of greater than 2 TB. Hybrid-MBR is an alternative style of partitioning that isn't supported by any version of Windows. However, the remaining capacity cannot be addressed and, therefore, cannot be used.
The following steps show how to initialize a fresh disk by using the GPT partitioning scheme to help ensure that Windows can address the maximum available storage capacity. Make sure that you back up any important data before you try these steps. Click Start , type diskmgmt. One Ultimate, one Professional. Any ideas on the issue? Wednesday, April 14, PM. Hi, According to my research, there is a 2TB in Windows system. Friday, April 16, AM. I have no problem reading mine. I have both. It's on.
Sometimes that will jar it. Also, make sure you have download drivers from internet enabled. Monday, April 19, PM. Your conclusion is flawed. You can use mbr up to 2TB. I have one this size and it works. His problem is not that. He cannot get the drive to appear in disk manager. Unmark your answer as correct. It isnt. Monday, May 17, PM.
