As a newbie to Mac, I recently researched Time Machine backups and found a very detailed tutorial from the minority:
But I didn't plan to buy MBP at first, so I bought WD My Passport Ultra, and made two NTFS partitions, and TIme Machine must use OSX partition format, so I did a little research.
First of all, my mobile hard disk is encrypted, and I already have 1T data, so I am very worried that if the file is encrypted, such as BitLocker or FileVault, it is estimated that it will not be solved in a day; the good news is that I tried it hard. It is found that the password can be cleared directly. The hard disk does this on the control chip, so it is very simple, and the password is removed immediately. The purpose of removing the password is not to cooperate with the backup, but to test whether the data can be directly read in the recovery mode of CMD+R without entering the password.
Then I backed up the 1T data first. . . The good news is that the second partition is rarely used, so use DiskGenius to dynamically resize the partition, freeing up 400G for Time Machine (I have a 256G ssd, and I only care about the last data, so this capacity should be enough, but also Can do something else).
After adjusting the 400G remaining space, as a mac novice. . . Well, I don't really want to use fdisk to partition, so I clicked the Disk Utility.app like other ordinary young people, and I was very happy to find that this product can't create partitions at all.
After researching for a while, I realized that the default partition table for co-authoring is MBR, and Apple only knows GUID, Apple format and what format, so the most straightforward approach is to continue to sacrifice DiskGenius to convert the partition table to GUID. . Then I don't know why Disk Utility still can't create a partition, the main reason is that the partition button is gray, so I created a partition with Windows but did not format it, so when I reconnect to the Mac, Disk Utility can select my 400G in the partition. space, then formatted, happy isn't it... and then got the prompt:
"Volume erase failed with an error Mediakit reported that there is enough space on the device to perform this operation" when wiping the disk

Another look, the original efi partition is less than 200M is not enough, according to this article, I had to delete the 400G RAW partition, and then found
DiskGenius can't create EFI partition (I didn't find how to create it anyway), so I have to continue to use windows:
diskpart
list disk
select disk 1 (choose your own according to your situation)
list partition (confirm the partition status)
create partition efi size=200
list partition (reconfirm the partition status)
Then continue to create a RAW partition with Windows Disk Utility, go back to Mac and format it into OSX log format.
This is divided into different areas, why does it feel like a bit of hands and feet and rushing with rolling and crawling. . . But now the hard disk has successfully become a mixture of NTFS and OSX partitions, the structure is as follows:
GUID Partition Table
1. NTFS partition 1
2. NTFS partition 2
3.EFI 200M
4. OSX partition
Considering that I don't use it as a boot disk, EFI will just stay in the middle and not put the new partition at the front.
