Partitioning schemes for windows 7

Now that the disk is initialized to access the full storage capacity, you must create a partition, and then format that partition by using a file system. Because the transition to a single-disk capacity of greater than 2 TB has occurred fairly recently, Microsoft has investigated how Windows supports these large disks.

The results reveal several issues that apply to all versions of Windows earlier than and including Windows 7 with Service Pack 1 and Windows Server R2 with Service Pack 1. To this point, the following incorrect behavior is known to occur when Windows handles single-disk storage capacity of greater than 2 TB:. The numeric capacity beyond 2 TB overflows.

It results in the system being able to address only the capacity beyond 2 TB. For example, on a 3-TB disk, the available capacity may be only 1 TB. The numeric capacity beyond 2 TB is truncated. It results in no more than 2 TB of addressable space. For example, on a 3-TB disk, the available capacity may be only 2 TB. The storage device isn't detected correctly. In this case, it isn't displayed in either the Device Manager or Disk Management windows.

Many storage controller manufacturers offer updated drivers that provide support for storage capacities of more than 2 TB. Contact your storage controller manufacturer or OEM to determine what downloadable support is available for single-disk capacities that are greater than 2 TB.

When a disk encounters errors that are related to unreadable or unwritable sectors, it reports those errors and the relevant SCSI sense data to the operating system. Therefore, the retrieved SCSI sense data either does not contain information about bad sectors or it contains incorrect information about bad sectors.

Administrators should note this limitation when they look for bad sector LBA information that's recorded in the Windows event log. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info.

Note This article refers to disk capacity in powers of two instead of powers of 10, which is the more common designation on storage device capacity labels. Therefore, references to 2 TB actually refer to a product that is labeled as having 2.

The operating system-specific behavior that is noted in this article also applies to the server variants of that system. Note When a non-initialized disk is detected by Windows, the following window opens to prompt you to initialize the disk.

Note If you select this option, this hard disk will not be recognized by Windows versions earlier than and including Windows XP. Note The display should now show that the full amount of available space in unallocated. RyanM: Just to check, will you need disk encryption? Show 2 more comments. Active Oldest Votes.

To enable the system to fully address the total capacity of the storage device, you must convert the disk to use the GPT partitioning scheme. Right-click the label on the left for the disk that you want to convert, and then click Convert to GPT Disk.
