## How?

The Xbox One initializes the external drive with a GPT (GUID Partition Table).

The original Boot Signature of the device 0x99CC (0x1FE-0x1FF) doesn't appear to allow the drive to be seen as initialized in Windows.

Swapping the two Boot Signature bytes with the traditional 0x55AA allows the NTFS partition to be seen be Windows.

## Notes

1. Windows will offer to initialize an Xbox One formatted disk. Don't do this unless you want to start everything again.
2. If the Boot Signature matches 0x99CC, the Xbox One will be able to read the partitions. Windows PC will not.
3. If the Boot Signature matches 0x55AA, a Windows PC will be able to read the partitions. Xbox One will not.
4. Windows might complain that there is something wrong with the disk and will want to run a chkdsk. I don't reccomend doing this.
5. Make sure you specify the right disk - don't come to me when it hits the fan.
