Scenario: you install GPT Loader to a Windows XP system. When partitioning a GPT drive, GPT Loader / GPT Manager doesn’t see the first 2 TiB from its beginning
This typically occurs when a high-capacity drive has been incorrectly initialised on a system that doesn’t support GPT and capacities ≥2 TiB. The partitioning data on the drive prevents the GPT Manager from properly reading it and other systems from recognising its full capacity. To solve this, you need to clear the partitioning information and re-initialise the drive as GPT. Do the following.
Start > All Programs > Accessories > Command Prompt.
diskpartto launch the disk partitioning tool. The prompt to the left will display
helpto see the list of available commands, or
help [command]to see hints for a particular command.
list diskto see the available disks, then
select disk Nto choose the high-capacity drive. Substitute
Nwith its actual number. Double and triple check to ensure this is the right drive, because we’re going to wipe it.
cleanto wipe all partitioning information from it.
Convert Hard Disk to GPT, and choose the high-capacity drive.
Partitioningto the left, and
Create a partition. Please keep in mind that on a 32 bit operating system it is not possible to manage partitions larger than 2.2 TB. Thus it is necessary to create several partitions any of them being smaller than 2.2 TB.
After that, the drive should be fully operable.
