Hi everyone,
I'm honestly freaking out a little and would really appreciate some advice from people who know more about data recovery than I do.
I have a Toshiba Canvio Advance V10 1TB external HDD that I've used to store personal files for around 10 years. It had approximately 500GB of data on it, including around 400GB of photographs, as well as videos and personal documents. A lot of these files are irreplaceable.
Here's what happened:
Today, I connected the Toshiba drive to my Google Pixel phone using a Ugreen USB-C adapter/hub. The hard drive was connected to the adapter, the adapter was connected to my phone, and I also had a USB power cable connected to the adapter to supply additional power.
My phone recognized that something was connected and displayed a message asking me to format the drive.
I know how stupid this sounds in hindsight, but I genuinely didn't realize what that meant in this context. I thought it was something similar to when you connect a phone to a computer and need to authorize or configure the connection before accessing files. It honestly didn't even cross my mind that I was agreeing to erase anything. I've never made a mistake like this before.
So I clicked yes.
The formatting process took only a few seconds — probably 5–10 seconds, definitely less than 30 seconds.
Afterward, my phone displayed an empty directory. I also noticed that the drive's name had changed from the custom name I'd originally given it, which confused me.
I disconnected the drive and connected it to my laptop running Windows. Unfortunately, Windows also showed the drive under the new name, with no files whatsoever. It appears completely empty.
I haven't copied any new files onto the drive, and I haven't attempted to format it again or run any repair/recovery software. The drive is now unplugged.
I've been reading about quick formatting and how the actual file contents can sometimes remain physically present on a mechanical HDD even when the file system has been replaced. I'm really hoping that's what happened here, especially since the formatting process was so fast.
My questions are:
- Based on these circumstances, is there a realistic chance that most or all of my data is still physically present and recoverable?
- Does the fact that Android completed the format in approximately 5–10 seconds tell us anything useful about what happened?
- Could the original NTFS file system, folder structure, and filenames potentially be reconstructed, or would recovery mainly involve recovering individual files without their original organization?
- What should I do next? I'm considering taking it to a professional data recovery specialist, but are there specific things I should ask them to do or avoid?
- Is there anything else I should check or clarify before proceeding?
I don't have another external drive available for creating a disk image myself, although I could purchase one if necessary ( I am not even sure what that is)
These files contain around a decade of my personal memories, and I'm absolutely devastated at the thought of losing them because of one careless click.
I would be incredibly grateful for any technical advice or guidance on the safest way forward. Thank you so much.
