So you have a lovely new Seagate GoFlex drive, and you have XP, well this is going to be annoying as the drive will be gormatted as a GPT drive, and 32bit XP can’t use it!
Compared with MBR disk, A GPT disk can support larger than 2 TB volumes where MBR cannot. A GPT disk can be basic or dynamic, just like an MBR disk can be basic or dynamic. GPT disks also support up to 128 partitions rather than the 4 primary partitions limited to MBR. Also, GPT keeps a backup of the partition table at the end of the disk. Furthermore, GPT disk provides greater reliability due to replication and cyclical redundancy check (CRC) protection of the partition table. It can be used as a storage volume on all x64-based platforms, including platforms running Microsoft Windows XP Professional x64 Edition. Windows Server 2003 SP1 also enables support for GPT in x86 versions of the Windows Server 2003 family.
However, with a bit of jiggery pokery you can reformat it to work!
In Windows XP Professional, you cannot access or modify GPT disk, but you can convert a GPT disk to MBR by using the clean command in DiskPart, which will delete GPT protective partition and remove all data and partition structures from the disk.
Warning: The steps below will erase all data on the GPT disk, please backup your data first.
You might see HD Drive in GPT status on Disk Management.
Go to DOS command line (click on “Start Menu”, then “Run”, type in “run” in textbox, and hit “OK”)
- Type in “DiskPart” in command line
- Type in “list disk” in command line to show all disks in this machine.
- Use “select” to set the focus to the specified partition.
- For example “select disk 1″.
- Use “clean” command to remove GPT disk from the current in-focus disk by zeroing sectors.
- Go back to Disk Management, you can see GPT disk is “Not Initialized” now.
- Within Disk Management, right click on disk info, choose “Initialize Disk”, You can see GPT disk is “Unallocated” now.
- Right click on disk info, choose “New Partition…”, follow Partition Wizard and format it. Now you are able to use the disk in Windows XP.
