Resized Mac OS volume and now windows bootcamp partition gone

I’ve looked at all the other threads that assess this situation, but my case is unique. I have a MacBook Pro 2017 with an intel chip, and I was trying to free up space. I clicked on “partition” from disk utility and the windows BOOTCAMP vanished, replaced with untitled. I tried to follow all the steps to recover my work but nothing helped.. i need my files back. This is over 4 years of work with thousands of files lost..


if someone knows Loner T on these threads, please redirect them to me!! I need these files!!!

MacBook Pro 13″

Unfortunately @LonerT has not posted on this forum in several years.


When you erase an SSD which has TRIM support enabled, all the data is immediately gone due to how SSDs work. There is no way to recover that data except by using a backup made before the fateful mistake. You can try using a data recovery app such as Stellar Data Recovery or Disk Drill assuming your macOS installation is still intact, but don't be surprised when nothing is found on the "Untitled" volume. Many data recovery apps allow users to run the app to see whether the app can locate any deleted files. Some apps may even allow the user to recover a few small files from those found.


Unfortunately many people learn the lesson about backups the hard way after losing some important files.

There has to be a way, so many people had the same issue and the same error recovered their data through terminal.


I did scan untitled using disk drill and found nothing, but my bootcamp still opens up to a blue error screen. The partitioning is still there, but maybe the data is allocated somewhere else on my mac.


please do let me know if you find a way that does lead to my files..

Those people would have been using a hard drive instead of an SSD. SSDs work differently than hard drives. When you erase an SSD the data is immediately gone when TRIM is enabled like it is on an Apple internal SSD. With hard drives when you delete data, you are only removing the links to the data.....the actual data still resides on the physical platters of a hard drive until that data is actually overwritten.

That is because the Windows bootloader still resides on the hidden EFI (aka ESP) partition. You would need to manually mount that partition using the command line so that its contents can be viewed in the Finder and delete the "windows" folder, then unmount that EFI partition.

Yes, because all you did was convert the Windows partition that used NTFS file system into a partition that now uses some other file system.

You've already proven that the data is gone as I mentioned in my previous post since Disk Drill did not find any files.


Is there by any chance another partition associated with the former Windows installation? If so, then your data may be there, but since you did not mention any other Windows partitions I'm assuming there are none & your Windows' data is gone unless you have another copy of those files stored elsewhere.


I'm sorry. I wish I had better news for you.
