My OS: Mac OS High Sierra
My problem:
I have a exfat formatted 4TB Western Digital Passport HDD crypted with veracrypt.
Yesterday out of nowhere i wasn't able to mount and got these error hdutil: attach failed.
I was able to successfully mount in readonly mode with the option Mount at directory: /volumes/1
but the problem was that when i tried to transfer the data it always stopped copying after 300gb.
I tried manually to transfer the data but only 60/70% of the files where are able to transfer successfully (same on windows and when i had one of these files which won't work to transfer then my mac or windows explorer crashed).
And cause i don't had time to transfer over 500.000 files manually each time with ultra slow speed
and when a coruppted file appears that crash my system
i decided to mount the HDD in mount only mode and tried to repair with diskutil.
End of the story i fcked up the filesystem (see terminal output below).
Diskutil splitted the image file in 5 (partitions?) FDisk_partition_scheme and 4x 0xF4.
And now im unable to mount even in readonly mode (same problem in windows.)

Can anyone help me?
I have very important data on it.......
and please don't judge me....

Nonexistent, unknown, or damaged partition map scheme
If you are sure this disk contains a (damaged) APM, MBR, or GPT partition
scheme, you might be able to repair it with "diskutil repairDisk disk3"
Macbooks-MacBook-Pro:~ macbook$ diskutil repairDisk disk3
Nonexistent, unknown, or damaged partition map scheme
If you are sure this disk contains a (damaged) APM, MBR, or GPT partition map,
you can hereby try to repair it enough to be recognized as a map; another
"diskutil repairDisk disk3" might then be necessary for further repairs
Proceed? (y/N) y
Partition map repair complete; you might now want to repeat the
verifyDisk or repairDisk verbs to perform further checks and repairs
