So the conversation to sectors is accomplished by multiplying by 8 to get 664,063,960 sectors, which is 340,000,747,520 bytes. In your case, there are 8 sectors per block.In this case, the result is 83,007,995 blocks, where a block is 4096 bytes. Use the Calculator application (or other equivalent means) to convert hexadecimal to decimal.Reverse the order and remove the leading zeros to get 4f299fb.This can be converted to 512 byte sectors by the following steps. In your case the bytes are fb 99 f2 04 00 00 00 00.

The size in blocks of a APFS container is stored in the 8 bytes at offset 40 (28 hexadecimal) of the partition. The sudo dd if=/dev/disk0s2 count=1 bs=128 | hexdump -Cv shows values stored at the beginning of the second partition on the internal drive. The sudo get -r show disk0 command shows values stored in the GUID Partition Table (GPT) on the internal drive. Then I boot to Bootcamp Windows, using the MiniTool Partition Wizard with the feature 'Extend Partition' to extend my Bootcamp (10GB).I use MacOS Disk Utility to resize the disk0s1 down, to have free space (10GB).To add info on what I did when resizing the Bootcamp: Please assist to guide me how to fix this if you know. 100 GB storage disk of my Mac data (the only one I can access now).300GB which is my main MacOS (I need to access its data).I saw some post to fix this by adjusting the 'hex' but I don't quite understand that, and it seems suitable for different case depending on different partition table, therefore I can't just apply blindly as my partition table is different with others. But still can't access the data from the main MacOS.ĭo you have any idea on how to fix this, if I can use my MacOS and Windows as before that is great, but in case it is difficult at least can I access to MacOS disk to just copy some important data? Now I have to use a temporary MacOS on my extend SSD.

I tried to increase the BOOTCAMP using MiniTool Partition Wizard.Īfter that both MacOS and Bootcamp Windows disappear from the boot menu (Power on then press Option). I have an issue accessing my MacOS data, can someone guide me how to fix this?
