What does Ubuntu do specifically to the drive when selecting quick format? Can we infer from that whether it is (im)possible to recover the file system at all?Ĭan I recover parts of the structure using Superblocks? Somewhere I read that a backup superblock is written at position 1024. Superblocks: superblock 0, blocksize=4096 In contrast, analyzing the drive after selecting the GPT-type results in many identical entries of this type: ext4 0 0 1 972801 80 63 156280533168 Selecting EFI-GPT or Intel as partition type results in Testdisk telling me that there are no partitions available.Īnalysis of the drive (after selecting None-type) results in the partition that is empty (except for an empty lost+found).See the following Testdisk snapshots for more info:Īdvanced menu after selecting None as partition type I did not yet attempt to perform a deep scan, as I expect the information to be at the very beginning of the drive (the drive is 8TB). Testdisk on the other hand, displays inconclusive prompts as far as I understand. I gave Photorec a quick try but since most of the important files are binary and have no file signature I ended up having thousands of useless. Reading through forums and blogs, I understood that Testdisk+Photorec might be able help recover the lost partition. The files I am after are in binary format (with no extensions as far as I am aware such as. Just a few seconds after the damage had been done, I unmounted the drive to avoid accidental writes. There was only a single partition on the drive. The drive was in ext4-format before and I did the quick format to ext4 again. I accidentally formatted one of my drives and I'm hoping that I can recover a major part of my file system as I 'only' did a quick format.Īfter installing a second identical hard drive, I quick formatted the wrong drive by accident via Ubuntu's (14.04) Disks-Application.
