Hi there. I am soliciting help to you. I have done a massive fail. I accidentally deleted a whole 2 TB disk containing lots and lots of important files. It is an external disk and there is no backups. Yeah, mistake. How I deleted it? Disk Utility App. I selected the partition on the left side, clicked on the "Delete" tab, and then clicked on the "Delete…" button. Then confirmed the deleted by hitting "OK" on the modal dialog, then I realized what I have done. Note: My machine is on Spanish language, so the button names and such may be different due to translation from Spanish to English. This is where all went wrong. Obviously is my mistake. Well… this is the question I need to ask you… is there a way to recover the whole disk? It is a GUID partitioned disk. Only 1 data partition. I think that been a GUID disk, there is a hidden 100MB partition for EFI or something like that. I unmounted the disk to avoid accidentally writings on the now-free-space that would overwrite the actual data. Lots of years ago, on a MS-DOS computer, I made a similar mistake. I deleted the MBR partition table for a disk. I solved the situation by binary-writing the MBR partition table, and after a reboot, all the data was there. Almost miraculous. Now, in this situation, do you know if a miracle can happen? What is your advice? I will update the post as I find useful information. Thanks.
