I have a TB external HDD divided in 2 partition:
First partition: 280 GB
Second partition: 1720 GB
Initially, both partitions were NTFS.
Then, I formatted the first partition to macOS Extended FS, and then to FAT32, and the second partition vanished. I can't see it in Disk Utilities nor in Paragon NTFS 15.
I tried to revert first partition to NTFS, but the second one is still not showing... What should I do?
here is the result of diskutil list

, but I doubt it will change my answer. Worth a try anyway. – David Anderson Dec 22 '17 at 19:01sudo dd if=/dev/disk2 bs=512 skip=446333006 count=50000000 | fgrep -o -a -b "BOOTMGR is compressed"
